Tom Primožič
Tom Primozic is a Slovenia-born, Zurich-based software engineer and mathematician. He represented Slovenia at the 2007 International Mathematical Olympiad, winning a bronze medal. He holds a BSc in Mathematics from the University of Ljubljana (2007-2010) and an MSc in Mathematical and Computational Finance from the University of Oxford (2010-2011). His professional career spans software and quantitative-finance engineering in London (software developer/architect at hedge fund Hutchin Hill Capital; developer and then quant developer at systematic investment firm GSA Capital), a data-engineering role at QuantCo, and AI-engineering roles in Zurich (CHARM Therapeutics, SuperFocus), most recently engineering at Boltz. Self-described interests span AI, robotics, aerospace, batteries, biotech and large-scale software.
- Employer classification - GSA Capital is a British quantitative investment firm doing systematic trading across asset classes, geographies and time horizons (self-described 'all-weather returns with systematic trading strategies'); Wikipedia describes it as 'a British quantitative finance investment firm ... systematic trading across equity, futures, and foreign exchange markets'. His GSA developer/quant-developer roles (London, 2015-2021) are therefore roles at a confirmed quantitative hedge fund.2026
- Quant employment verification: CONFIRMED. Identity is supported: primozic.org, GitHub tomprimozic and LinkedIn /in/tomprimozic cross-link to the same Slovenia-born Zurich engineer and mathematician. Actual past roles at quantitative-finance employers: Developer (2015-2018) and Quant Developer (2018-2021) at GSA Capital, a British systematic/quantitative investment firm (per gsacapital.com and Wikipedia), and Software Developer and Architect (2013-2015) at Hutchin Hill Capital, a global multi-strategy hedge fund with systematic/quantitative strategies (per third-party hedge-fund profiles). His own site corroborates: he 'bootstrapped the entire technology stack of a small trading team in an award-winning multi-billion-dollar quant hedge fund.' By contrast, QuantCo (Data Engineer, 2021-2022) is a consulting firm, not a quantitative-finance employer, and his later roles (CHARM Therapeutics, SuperFocus, Boltz) are AI/software, not trading. So confirmed quant-finance employment rests on GSA Capital and Hutchin Hill Capital; the timeline is index-only (LinkedIn), while the employer classifications are supported by primary (company) and third-party sources.
- Career timeline (LinkedIn index-only, treated as index-only not independent primary-source confirmation), newest first: Engineering at Boltz (Zurich, 2026-); AI Engineer at SuperFocus (Zurich, 2023-2026); AI Engineer at CHARM Therapeutics (Zurich, 2022-2023); Data Engineer at QuantCo (Zurich, 2021-2022); Quant Developer at GSA Capital (London, 2018-2021, 'Global macro trading team'); Developer at GSA Capital (London, 2015-2018, 'Scala, Python'); Software Developer and Architect at Hutchin Hill Capital (London, 2013-2015); Developer at Zemanta (Zurich, 2011-2013).
- Personal-site work narrative: he 'bootstrapped the entire technology stack of a small trading team in an award-winning multi-billion-dollar quant hedge fund' and 'managed and troubleshot critical live processes with millions of dollars on the line for global corporations and hedge funds' - consistent with the GSA Capital and Hutchin Hill Capital roles.
- Employer classification - Hutchin Hill Capital was a global multi-strategy hedge fund (founded 2007 by Neil Chriss) running long/short equity, events, credit, and systematic/quantitative strategies. His 'Software Developer and Architect' role there (London, 2013-2015) was at a hedge fund with quantitative strategies.
- Employer classification - QuantCo is a data-science/engineering consultancy ('leverages expertise in data science, engineering, and economics to help organizations turn data into decisions'); despite the name it is not a quant trading firm. His Data Engineer role there (2021-2022) was a software/data role at a consulting company, not a trading role.
- Identity corroborated: primozic.org (his personal site, titled 'Tom Primozic') links his work history and GitHub; his GitHub account tomprimozic and LinkedIn /in/tomprimozic both point to the same person. The personal site self-describes him as 'a technology enthusiast, programmer, mathematician and amateur chef.'
- Education (LinkedIn index-only): MSc Mathematical and Computational Finance, University of Oxford (2010-2011), dissertation 'Estimating expected first passage times using multilevel Monte Carlo algorithm' (per Google Scholar); BSc Mathematics, University of Ljubljana (2007-2010); secondary school Gimnazija Bezigrad, Ljubljana. Separately, COBISS (Slovenian national bibliography) lists a 2010 Ljubljana diploma-seminar work by 'PRIMOZIC, Tom', 'Problem kockarjevega propada' (The gambler's ruin problem), consistent with the Ljubljana mathematics degree.
- Personal-site work narrative: 'most recently, I've scaled drug discovery pipelines to billions of molecules and hundreds of GPUs' (matches CHARM Therapeutics, AI + drug development) and 'I am the technical co-founder of a data-driven art investment startup, where I build websites, data pipelines, ML algorithms and manage contractors.'
- IMO 2007 (Slovenia): Tom Primozic scored 14 points (problems 7,0,0,7,0,0) and won a bronze medal; individual rank 226 of 520. This is a competition, not employment.
- GitHub account github.com/tomprimozic (uid 84324) is the subject's developer account - it is linked from his LinkedIn profile_urls and matches his name.
- F6S member profile lists 'Developer @Zemanta' and 'University of Oxford', consistent with the 2011-2013 Zemanta role and Oxford MSc.
