Notes6

• Quant employment verification: UNRESOLVED. The only evidence of a G-Research role is a LinkedIn index entry, labeled index-only and not independently confirmed: it lists Software Engineer at G-Research with a July 2026 start date, with no primary confirmation from G-Research, a press source, a resume, or a repository. The identity behind the profile is well supported (name, Finland, IOI record, GitHub account), but the employment claim is not. Employer classification: G-Research is a genuine quantitative-finance firm (quantitative investment/research, UK) and would qualify if the role were real; OpenBlock Labs, listed in the same index as a 2026 Member of Technical Staff role, is an AI-agent and crypto/DeFi analytics project, not a quantitative trading firm. CONFIRMED is withheld because the role rests on index-only evidence and its start date is uncorroborated; no student program or incoming offer is involved.Sep 2026
• Identity corroborated across independent primary sources: the official IOI statistics page (stats.ioinformatics.org/people/7452) and the CPHOF profile both list Leo Varis competing for Finland at IOI 2022 and 2023, matching the LinkedIn index profile carrying the same name and Finland/United Kingdom location.Sep 2023
• G-Research is a United Kingdom quantitative research and technology firm applying machine learning and large-scale data analysis to financial markets, recruiting quantitative researchers, quantitative developers and software engineers; its own careers pages list quantitative-researcher and quant-research-internship roles.Sep 2026

• Index lists a 2026 Member of Technical Staff role at OpenBlock (San Francisco) contributing to the OB-1 self-improving autonomous coding agent; OpenBlock Labs operates in the AI-agent and crypto/DeFi analytics space rather than quantitative trading, so this role would not count as quantitative-finance employment even if accurate.Sep 2026
