• Quant employment verification: CONFIRMED. Timo Lörke's LinkedIn profile lists a 2025 role as 'Quantitative Trading Intern' at Jane Street (company_domain janestreet.com). His identity is independently corroborated across IMO results (Germany, 2021 silver / 2022 bronze), his Bonn BSc and Cambridge MASt timeline, and calimath.org co-authorship, so the profile is the substantiated person. Jane Street is a proprietary trading firm and market maker whose business is quantitative/securities trading, so the role falls squarely in quantitative finance. Caveat: the role rests on the LinkedIn profile (self-reported) via a profile index/aggregator, not on an independent Jane Street staff page; no further role evidence was found.2025
