• Quant employment verification: CONFIRMED. Emil Baronov worked as a Software Engineer at Hudson River Trading (HRT) from 2018 to 2023 per LinkedIn-derived enrichment. HRT is a proprietary quantitative trading firm and market maker (industry listed as Capital Markets), so the employer is genuinely in quantitative finance, not merely 'quant' by name. Identity is supported by cross-links: a 2023 efinancialcareers article explicitly names 'Hudson River Trading engineer Emil Baronov' as a Sofia University St. Kliment Ohridski alumnus, matching the LinkedIn profile's Sofia University and Stanford education and New York location. Caveat: role and dates rest on index/aggregator evidence (LinkedIn enrichment, Wiza) plus one press mention, not on an HRT-published primary source; no HRT page named him.Jan 17, 2023
