In the autumn of 2016, James Hoffmann published nine podcast episodes under a deliberately blunt title: The Coffee Jobs Podcast. The framing he used to introduce the project, syndicated through his RSS feed and quoted across the trade press, was even blunter:
“Coffee is a dead-end job, but it doesn’t have to be. The boom in speciality coffee has created a crisis in employment in many parts of the world, but it has also created an opportunity that we must grasp if we want both growth and lasting success for the industry.”
Hoffmann was, at that point, nine years past his 2007 World Barista Championship win in Tokyo and eight years into running Square Mile Coffee Roasters in London with co-founder Anette Moldvaer. He was the rare industry voice whose audience extended well beyond people behind a bar — The World Atlas of Coffee had been on coffee-shop bookshelves since 2014 — and he was using that audience to say something the industry was reluctant to admit. A lot of the people pulling its shots could not afford to keep doing it, and a lot of the talent it was losing did not need to be lost.
A decade on, that frame still stings. It also still works. This article maps the careers Hoffmann profiled in the original Coffee Jobs Podcast, what each of those people went on to do, and what an aspiring barista, roaster, or buyer can actually build in 2026 — when the industry has matured but its compensation problem has not entirely gone away.
Quick Takeaways
- Hoffmann’s thesis still holds. The original Coffee Jobs Podcast (2016) argued that coffee is a dead-end job only when employers fail to value or develop transferable skills. That diagnosis has aged better than most career advice from a decade ago.
- Nine guests, nine career maps. Hoffmann interviewed Colin Harmon, Gwilym Davies, Michael Phillips, Anne Lunell, Charles Babinski, Laila Ghambari (then Wilbur), Mikaela Wallgren and Klaus Thomsen (joint episode), Ellie Hudson, and Jenni Bryant. Every one of them used a barista bar as a starting line, not a finish line.
- The roles have multiplied since 2016. Green coffee buyer at scale, YouTube coffee educator, equipment-design consultant, café-operations CFO, and full-time competition coach are all paths that barely existed when Hoffmann recorded the podcast.
- The pay problem is real but unevenly distributed. A career barista at a high-volume specialty cafe in 2026 typically earns more than they did in 2016, but the meaningful gains accrue to people who specialize.
- Geography concentrates opportunity. London, Melbourne, Copenhagen, Oslo, Tokyo, Los Angeles, and Portland still hold a disproportionate share of the industry’s career-track jobs.
- Competition wins are useful currency, not a destination. Every WBC champion in this article used the title to leverage something else: a roaster, a training school, a consulting practice, a book.
The Coffee Jobs Podcast: Hoffmann’s 2016 Thesis
Hoffmann’s own framing of the project, on his portfolio site, is brief: “The Coffee Jobs Podcast was created to dive deeper into the challenges around both hiring and career progression in the coffee industry.” The thesis paragraph that ran with the podcast at launch — the “coffee is a dead-end job, but it doesn’t have to be” line — went further. Hoffmann was arguing that specialty coffee’s growth had outrun its career architecture. Cafes were opening faster than they could train people, training pipelines were ad hoc, wages were stuck, and the most promising baristas were either burning out or leaving for industries that knew how to pay and promote them.
His remedy, threaded through every episode, came down to two ideas. The first was that great employers value transferable skills — leadership, palate, hospitality, communication, project management, science literacy — rather than just speed at the bar. The second was that the industry’s existing roles were far more porous than they looked from the customer side of the counter. A skilled barista could become a quality manager could become a green buyer could become a sourcing consultant could become a roaster. The path was real; what was missing was the map.
The podcast was, in effect, that map. Across nine episodes between August and October 2016, Hoffmann interviewed coffee professionals whose careers had taken them through almost every node on the org chart of a modern specialty company.
By 2016, Hoffmann’s own résumé made him plausible as a guide. He had won the World Barista Championship in Tokyo in 2007 with a routine that paired single-estate Costa Rican and Kenyan coffees with a tobacco-and-almond signature drink, in front of a panel that scored him on espresso, cappuccino, and signature beverage execution alongside more than forty other national champions. A year later, in 2008, he and Anette Moldvaer — who had won the 2007 World Cup Tasters title the same year Hoffmann won WBC — founded Square Mile out of a railway arch in East London with a single roaster and a delivery bike. By the time the Coffee Jobs Podcast launched, Square Mile was one of the largest specialty wholesalers in London, The World Atlas of Coffee (Mitchell Beazley, 2014) was on its way to half a million copies sold across multiple language editions, and Hoffmann’s YouTube channel was beginning the climb that would eventually make it the largest coffee-education resource on the internet.
In other words: the person making the case that coffee careers could compound was someone whose own career had visibly compounded. That mattered.
Career Paths the Podcast Mapped
The nine guests were not chosen for their fame. They were chosen because each one’s trajectory illustrated a different kind of compound career — different industry node, different geography, different specialty. The single most useful exercise a young barista can do with the original podcast feed is to listen to all nine episodes back-to-back and notice that no two paths look the same.
Colin Harmon — Cafe Operator to Industry Author
Episode 1, August 15, 2016. Harmon is a four-time Irish Barista Champion and a 2009 World Barista Championship finalist (fourth place) who founded 3fe in Dublin in 2009 — initially as a one-person coffee cart in a nightclub lobby, eventually as a roaster, two cafes, a wholesale program, a training arm, and an equipment-development practice that today employs roughly 45 people. In 2017, the year after Hoffmann interviewed him, Harmon published What I Know About Running Coffee Shops through Square Mile’s imprint. The book is now a standard text for anyone considering a cafe of their own. His career arc — bar to ownership to authorship — is one of the most legible templates in the industry.
Gwilym Davies — Champion to Educator
Episode 2, August 24, 2016. Davies won the 2009 World Barista Championship and was one of three founding owners of Prufrock Coffee in London — a cafe that, in the early 2010s, was almost a finishing school for the next generation of British baristas. He retains an ownership stake in Prufrock but has spent the past decade based in the Czech Republic, where he runs the Kávovékurzy training school in Jílové u Prahy with his partner Petra Veselá. The school is split between an espresso-focused room and a brewing-and-sensory room and has trained a substantial portion of Prague’s specialty cohort. Davies’s career is a clean illustration of the pivot from competitor to educator — the path Pete Licata (2013 WBC) and several other champions have since taken.
Michael Phillips — Champion to Global Director of Education
Episode 3, August 31, 2016. Phillips became the first American to win the World Barista Championship, taking the title in London in 2010. He had been working at Intelligentsia in Chicago when he won the US Barista Championship in March 2009, and at the time of his world title was Intelligentsia’s director of coffee education. In 2011 he resigned to co-found Handsome Coffee Roasters in Los Angeles with Tyler Wells and Chris Owens. Handsome was acquired by Blue Bottle in April 2014, and Phillips moved into education at Blue Bottle in Los Angeles. He has since held a series of leadership roles there — Director of Training, Director of Cafe Experience, Director of Coffee Culture, and Global Director of Education & Engagement — and currently serves as Blue Bottle’s Senior Editorial Director, where he focuses on coffee storytelling, training programs, and connecting Blue Bottle’s staff and guests to the broader specialty industry. His arc — competition → roaster founder → education executive — is the single clearest example of how a championship win can be cashed in for institutional influence.
Anne Lunell — Champion to Sourcing Lead
Episode 4, September 8, 2016. Lunell co-founded Koppi Roasters in Helsingborg, Sweden in 2007 with Charles Nystrand, the year she won the Swedish Barista Championship. She added the Swedish Brewers Cup title in 2016. Koppi began as a coffee bar with an in-store roaster and pivoted in 2016 to focus on roasting and wholesale from a converted industrial building. Within the company, Nystrand handles roasting; Lunell travels to origin and runs sourcing — building long-term relationships with producers and pushing for higher producer-side value capture. Koppi has consistently been named among the top hundred roasters in the world. Lunell’s career embodies the green-coffee-buyer track for a roaster founder: champion barista → roaster founder → director of sourcing.
Charles Babinski — Bar to Cafe Group Owner
Episode 5, September 15, 2016. Babinski began behind a bar in Manhattan at nineteen and eventually spent more than a decade at Intelligentsia, where he competed for the company in multiple barista championships. He partnered with Kyle Glanville to launch G&B Coffee in 2012 as a pop-up at Sqirl in Los Angeles, then opened Go Get Em Tiger (GGET) in 2014. In February 2015 he won the US Barista Championship, and that April he finished runner-up at the 2015 World Barista Championship in Seattle — Sasa Sestic of ONA Coffee took the title that year. Hoffmann interviewed Babinski eighteen months later, after the WBC podium had already become a backdrop to GGET’s growth. By 2018 the company had its own roastery and four locations across Los Angeles. The competition résumé, on the GGET timeline, sits in the middle of his ownership career rather than at its start. That sequencing is part of what makes his episode useful: competition wins, in his case, did not precede the cafes; they ran alongside them.
Laila Ghambari — Champion to Director of Coffee to Owner
Episode 6, September 22, 2016 (released as “Laila Willbur” on the original feed — her then-married name; she now works publicly as Laila Ghambari again). Ghambari won the 2014 US Barista Championship while at Cherry Street Coffee in Seattle and represented the United States at the 2014 World Barista Championship in Rimini. Her winning routine fused coffee-cherry jam, coffee-flower-blossom honey, and live-on-stage coffee-tree-wood smoke from El Manzano in El Salvador — among the most ambitious sourcing-as-storytelling routines a US competitor had attempted. By 2016 she was Cherry Street’s Director of Coffee and chair of the United States Barista Guild. In 2024 she and Ryan Wilbur — her now-husband — bought Portland’s Guilder cafe and Junior’s Roasted Coffee from their previous owners. Her arc closes a particular loop: competition → quality leadership → ownership.
Klaus Thomsen and Mikaela Wallgren — The Coffee Collective Joint Episode
Episode 7, September 29, 2016. This one was a joint interview, and it has its own longer profile coming on this site. The short version: Thomsen won the 2006 World Barista Championship in Bern, Switzerland — Denmark’s fourth WBC title in six years — and the following year co-founded Coffee Collective in Copenhagen with Casper Engel Rasmussen and Peter Dupont. The roastery opened in 2007 and the first cafe opened on Jægersborggade, Nørrebro, in 2008. By the late 2010s Coffee Collective was one of the most influential direct-trade operations in Europe, publishing the green prices it paid for every lot. Wallgren, a Finnish Brewers Cup champion, was a senior barista and HR coordinator at Coffee Collective at the time of the podcast and went on to take silver at the 2016 World Brewers Cup with a Kieni from Mugaga in Nyeri, Kenya. JavaPresse’s later “podcasts for students” roundup picked this episode as their single recommended Coffee Jobs episode, partly because the Thomsen-Wallgren pairing is a textbook illustration of two career tracks — founder/competition champion and barista-to-people-operations — running through the same building.
Ellie Hudson — Trade Association Career
Episode 8, October 6, 2016. Hudson was, at the time of the recording, Director of Professional Development at the Specialty Coffee Association of America (the SCAA, prior to its 2017 merger with the European SCAE to form today’s SCA). Her episode is the structural complement to the others: where Harmon, Davies, Phillips, Lunell, Babinski, Ghambari, and Thomsen all built or led commercial coffee operations, Hudson’s career was inside the trade body that builds the credentialing — barista skills, brewing, sensory, green-coffee, roasting — that those operations depend on. For a barista who likes coffee but does not necessarily want to own a cafe, the trade-association track is the path Hudson maps.
Jenni Bryant — Cafe-Group Operations in Melbourne
Episode 9, October 13, 2016. Bryant worked in operations at Market Lane in Melbourne, one of the most influential Australian specialty roasters of the 2010s (founded 2009). The Market Lane career path — cafe operator, customer-experience designer, retail-systems manager, training lead, distribution coordinator — is a useful counterpoint to the founder-track episodes. Most jobs in coffee, even at the best operations, are not cafe-owner jobs. Bryant’s episode profiled the operations track that sits underneath every multi-cafe roaster in the world.
The Career Paths That Have Emerged Since 2016
The architecture Hoffmann mapped in 2016 has not been displaced. It has been extended. Several roles that barely existed when the Coffee Jobs Podcast recorded are now serious career options.
The full-time green coffee buyer at scale. In 2016, most roasters under a few thousand kilos a week sourced through importers. Today, mid-sized roasters routinely have a dedicated buyer who travels to origin two or three times a year, runs cupping panels at home, and manages multi-year contracts. Anne Lunell’s Koppi role is no longer unusual; it’s the template.
The YouTube coffee educator. Hoffmann’s own channel — which crossed a million subscribers years ago — proved the audience exists. The Coffee Compass, European Coffee Trip, Lance Hedrick, Morgan Drinks Coffee, and dozens of others have built full-time careers on the back of long-form video education. None of those careers existed inside the Coffee Jobs Podcast window. All of them have downstream economics — sponsorship, equipment partnerships, courses, books — that match a competent cafe-management salary or exceed it.
The equipment-design consultant. A class of barista-turned-engineer now works directly with grinder, espresso-machine, and brewer manufacturers on product design. Some of these consultants come from competition backgrounds; others come from cafe operations. The role compounds because manufacturers want feedback from people who have actually used a piece of equipment ten thousand times.
The café-operations CFO. As specialty groups have grown — five-cafe, ten-cafe, fifteen-cafe operations are no longer rare — they need real financial leadership. The operations track Jenni Bryant represented in 2016 has split, with the senior end of that track now resembling a small-business CFO role: P&L ownership, capital planning, lease negotiation, banking relationships. People are moving into these roles from inside the industry rather than being hired in cold from finance.
The full-time competition coach. Pete Licata, the 2013 WBC, is the canonical example: he runs Licata Coffee Consultants out of Australia, where he coaches competitors and consults with cafes. Coaching is now itself a billable specialty. Several recent WBC podium finishers have been coached by past champions on retainer.
The specialty-coffee author. Colin Harmon’s 2017 What I Know About Running Coffee Shops was an early entry. Hoffmann’s World Atlas of Coffee (now in its third edition) and The Best Coffee at Home anchor the category. Lance Hedrick, Scott Rao before him, and a growing cohort of others have made writing — books, courses, paid newsletters — a real revenue line on top of operating roles.
The common thread: every one of these new paths is downstream of the same insight Hoffmann was pushing in 2016. People who develop transferable skills — sensory, communication, sourcing, science, leadership — keep finding new places those skills get paid. People who don’t, hit the bar-tender ceiling.
What Makes Coffee Careers Different
The compensation conversation in coffee is uncomfortable because the truth is mixed. A career barista at a high-volume cafe in a major specialty city — Melbourne, Copenhagen, London, Tokyo, San Francisco — typically earns more in real terms in 2026 than they did in 2016. Tipping economics have shifted; minimum wages have risen; some cities now have tipped-wage requirements that did not exist a decade ago. The ceiling, however, is still real. A purely customer-facing career maxes out, in most markets, around the median income of the local hospitality sector — which means a senior barista in London or New York is making meaningfully less than a senior software engineer’s first-year salary.
What changes the math is specialization. A barista who becomes a quality lead, a head trainer, a roaster, a green buyer, an operations manager, an educator, or a founder is on a different curve. That is the structural fact Hoffmann’s “transferable skills” framing was pointing at. Coffee careers compound when they specialize, and they stagnate when they don’t.
A few practical observations on how this plays out:
- Apprenticeship still beats certification. The SCA’s credential ladder — Coffee Skills Program, Q-grader, Authorised SCA Trainer — is meaningful, especially for the sensory and green-coffee-buying tracks. It is rarely the thing that gets someone hired. What gets people hired is a recognizable cafe or roaster on the résumé and a reference from someone the hiring manager already trusts.
- Geographic concentration is real. London, Melbourne, Copenhagen, Oslo, Tokyo, Los Angeles, Portland, Seattle, and increasingly Seoul host a disproportionate share of the industry’s senior roles. A barista in a smaller market who wants to specialize often has to relocate for at least a few years.
- Competition is leverage, not a job. Every WBC champion profiled above used the title to anchor something else. None of them treats winning as the career. The pattern is consistent enough that aspiring competitors should plan their post-competition life — book, training program, consultancy, sourcing role — before they win, not after.
- The paths are porous in both directions. A roaster can become a buyer can become a consultant can become a cafe owner can become an author. The reverse path also works.
Building a Coffee Career in 2026: Concrete Tracks
Pulling together the Coffee Jobs Podcast roster, the roles that have emerged since, and the structural realities above, a young coffee professional in 2026 can plan against six or seven concrete tracks.
The bar specialist (lead barista track). Stay behind the bar, but get extremely good. Enter regional and national competitions. Develop a reputation for hospitality and beverage construction. A lead-barista or head-of-bar role at a top cafe is itself a meaningful career — and it is the only path on this list that does not require giving up the part of the job most baristas actually love.
The trainer. Move into education at a roaster, an SCA-accredited training campus, or your own school. Gwilym Davies’s Kávovékurzy and Pete Licata’s consultancy are templates at the high end; many roasters now have a dedicated training role inside the company.
The roaster. Apprentice on a small production roaster, then on a larger one. Most roasters of any scale will train internally for the right person. Roasting is the technical track inside coffee that translates most directly into ownership later — the production knowledge is hard to fake and increasingly central to a brand.
The green buyer / sourcing professional. This is the longest path. It typically takes five to ten years of cumulative cupping, origin travel, and importer relationships. Anne Lunell’s Koppi role is the founder-level version; almost every mid-sized roaster now has a dedicated buyer, and importer companies (Cafe Imports, Caravela, Mercanta, Royal, Bodhi Leaf) employ a significant number of green professionals as well.
The operations track. Cafe management, multi-unit operations, retail systems, customer experience design, finance. This is Jenni Bryant’s track and it scales with the company. A senior operations role at a ten-cafe specialty group in a major city pays more than most other paths on this list.
The educator-creator. Long-form video, paid courses, books, newsletter, consulting. Hoffmann’s own platform is the high ceiling; dozens of smaller creators have built mid-five-figure to low-six-figure incomes. Requires a real craft skill, real on-camera competence, and a multi-year audience build.
The founder. A cafe, a roaster, a cafe-and-roaster, an equipment company, a green-trade company. The math is hardest here and the failure rate is high, but every other path on this list ultimately depends on people who have taken this one. Colin Harmon’s 3fe, Anne Lunell’s Koppi, Klaus Thomsen’s Coffee Collective, Babinski and Glanville’s GGET, and Ghambari and Wilbur’s Guilder are five examples from this article alone.
The consistent advice across all these tracks, drawn from the Coffee Jobs Podcast episodes and from the careers of the people who appeared on them: pick one specialty and go deep, while keeping enough surface-area in adjacent skills that you can move sideways. Don’t wait for a promotion at a cafe that does not have an org chart. Build the relationships that allow the next move before you need it.
Further Listening and Reading
The Coffee Jobs Podcast is no longer hosted at its original domain, but the original episodes are archived publicly via the Internet Archive and remain valuable listening even a decade on. A handful of other podcasts and resources are worth pairing with it for anyone thinking seriously about a coffee career in 2026.
- Boss Barista (Ashley Rodriguez, originally co-hosted with Jasper Wilde) — the most-cited coffee podcast on labor, equity, and the social architecture of coffee work. Now archived on Substack at
bossbarista.substack.com. Profiled in our companion piece on the women-in-coffee equity movement. The separately-named I Brew My Own Coffee (Bryan Schiele on Simplecast) is a different podcast that simply shares an audience. - Cat & Cloud Podcast (Chris Baca, Jared Truby). Cafe operations and small-business coffee leadership.
- Tamper Tantrum (Colin Harmon and Stephen Leighton, with Jenn Rugolo producing). One of the longest-running specialty industry podcasts and live-event series; archived episodes — including talks from Matt Perger and dozens of other industry figures — remain essential listening.
- The Coffee Podcast (Jesse Hartman, Austin) and Keys to the Shop (Chris Deferio). Both cover operations, hospitality, and leadership; Keys to the Shop has interviewed Phillips, Babinski, and many of the original Coffee Jobs guests with more recent career updates.
- Stone Creek Coffee Podcast and Tim Wendelboe Podcast. Roaster-led shows from established specialty companies.
- Hoffmann’s YouTube channel. The single largest open library of coffee literacy on the internet, and a useful real-time read on what the industry is paying attention to.
- Books. Hoffmann’s The World Atlas of Coffee (Mitchell Beazley) and The Best Coffee at Home. Colin Harmon’s What I Know About Running Coffee Shops (Square Mile, 2017). Scott Rao’s The Professional Barista’s Handbook. Jonathan Morris’s Coffee: A Global History.
- Trade press. Barista Magazine, Sprudge, Daily Coffee News, Perfect Daily Grind, and Fresh Cup between them cover almost every senior hire and major company event in specialty coffee.
The deeper pattern in all these resources — and in the original Coffee Jobs Podcast — is the one Hoffmann named at the start: coffee is a dead-end job only when its employers, and its employees, treat it as one. Specialty coffee in 2026 has more career paths inside it than at any prior moment in its history. The dead ends are still there. So are the doors.
Frequently Asked Questions
- Is coffee really a dead-end job?
- Not inherently. James Hoffmann's framing in the 2016 Coffee Jobs Podcast — "Coffee is a dead-end job, but it doesn't have to be" — captured the industry's pre-pandemic problem. Cafes were losing skilled people because the path beyond a senior bar role was not visible from inside the cafe. A decade later, the path is more visible. Specialty coffee in 2026 employs people in roastery-floor, green-trade, training, sensory-quality, retail-operations, finance, and education roles, most of which start with a barista résumé.
- Who hosted the Coffee Jobs Podcast and when?
- James Hoffmann — 2007 World Barista Champion, co-founder of Square Mile Coffee Roasters, and author of The World Atlas of Coffee — hosted nine episodes between August 15 and October 13, 2016. The original feed lived at coffeejobspodcast.com; archived episodes remain available via the Internet Archive.
- Who were the guests on the Coffee Jobs Podcast?
- In order: Colin Harmon (3fe Dublin), Gwilym Davies (2009 WBC, Prufrock, Kávovékurzy), Michael Phillips (2010 WBC, Handsome, Blue Bottle), Anne Lunell (Koppi Roasters), Charles Babinski (G&B / Go Get Em Tiger), Laila Ghambari (2014 USBC, Cherry Street, now Guilder/Junior's), Mikaela Wallgren and Klaus Thomsen (joint episode — Coffee Collective Copenhagen, Thomsen the 2006 WBC), Ellie Hudson (SCAA), and Jenni Bryant (Market Lane Melbourne).
- What is a realistic salary for a barista in 2026?
- In a major specialty city — London, Melbourne, Copenhagen, New York, San Francisco — a senior barista at a high-volume cafe typically clears the local hospitality-sector median once tips are included, and a quality lead, head trainer, or operations manager earns meaningfully more. The biggest jumps come from specialization: roaster, green buyer, training lead, and operations roles all out-earn a pure-bar career. Outside the major specialty cities, the math is harder.
- Do you need to win a barista championship to build a coffee career?
- No. Of the nine Coffee Jobs Podcast guests, three were World Barista Champions (Davies, Phillips, Thomsen), one was a USBC champion at the time (Ghambari), several had national-level finishes, and several had no major competition résumé. Competition is one form of professional credibility — it is not the only one, and most senior roles in the industry are held by people who never made a national final.
- What is the single most useful skill for advancing in coffee?
- Hoffmann's own answer in 2016 was "transferable skills" — leadership, palate development, hospitality, communication, science literacy, project management — applied to whatever specialty you pick. Almost every senior coffee professional combines deep technical mastery in one area with adequate competence in three or four adjacent ones. That mix is what makes someone hireable across roles, which is what makes the career compound.
