DĆDomagoj Ćevid
Zurich, Switzerland · engineerDomagoj Ćevid is a Croatian mathematician and machine-learning engineer. He won a silver medal at the International Mathematical Olympiad (IMO) 2011 and gold medals at IMO 2012 and 2013 competing for Croatia, and silver medals at the International Olympiad in Informatics (IOI) 2012 and 2013. He read mathematics at the University of Cambridge (BA 2013-2016, MMath 2016-2017) and completed a PhD in Statistics at ETH Zurich in 2021 under Peter Bühlmann (co-examiner Nicolai Meinshausen), with a thesis titled 'Confounding adjustment for causal inference'. He then worked at Google in Zurich as a Data Scientist (2021-2024) and as a machine-learning engineer on model tuning/quality for Gemini/Bard (2024), and is listed as a machine-learning engineer on LLM post-training at Google DeepMind. He held a summer trading internship at Jane Street in London in 2015.
- Quant employment verification: CONFIRMED for one quant-finance role. He held a Trading Intern role at Jane Street (London) in 2015 — Jane Street is a proprietary trading firm / market maker, so this is a genuine quantitative trading internship, not a student program. Evidence is a LinkedIn-derived index record (not independent primary-source confirmation). His current role is at Google DeepMind (technology, not finance). No other quantitative-finance employer is evidenced.2015
