• Quant employment verification: UNRESOLVED. The employment timeline (Jane Street software developer internship 2018; Radix Trading LLC quantitative technologist 2019-2021; Tower Research Capital quantitative trader from Oct 2021) is index-derived from the LinkedIn profile linkedin.com/in/felix-bauckholt and repeated by news reporting (efinancialcareers.com/news/felix-bauckholt; torontosun.com; en.wikipedia.org/wiki/Zizians), which repeats the same online profile rather than confirming it from an independent primary source; no independent primary-source employment record was found. Employer classification: Jane Street is a proprietary trading firm / market maker; Radix Trading LLC is a proprietary trading firm; Tower Research Capital is a high-frequency trading market maker - all three operate in quantitative finance, so classification does not rest on a company name containing 'quant'. Identity is supported (German national; University of Waterloo; IOI 2014 gold and 2015 bronze). Olympiad participation is a competition, not employment and not evidence of a role.Jan 23, 2025
• Died in January 2025 in a shootout with U.S. Border Patrol agents on Interstate 91 in Orleans County, Vermont; Border Patrol agent David Maland was also killed. Press reporting and the Wikipedia article on the Zizians name Ophelia Bauckholt as one of the associates killed.Jan 20, 2025
• Joined Tower Research Capital in October 2021 as a Quantitative Trader in the New York office, per his LinkedIn profile as reported in January 2025. Tower Research Capital is a high-frequency trading market maker and proprietary trading firm (press describes it as a high frequency trading firm with ~1,200 employees).Jan 23, 2025
• All three private-sector employers in his work history - Jane Street, Radix Trading, and Tower Research Capital - are proprietary trading / market-making firms operating in quantitative finance, so the quant-finance classification does not rest on a company name containing 'quant'.Jan 23, 2025
• An efinancialcareers article reported his H1B visa was 'allegedly expired' at the time of the stop, while noting Tower Research would not confirm his recent employment status - so the 'current' Tower role reflects his LinkedIn profile as of Jan 2025, not a live confirmation.Jan 23, 2025
• Worked as a Quantitative Technologist at Radix Trading LLC in Chicago, Illinois, from 2019 to 2021 (about two years). Radix Trading is a proprietary trading firm.2021
• News reporting said Bauckholt was transgender and used the name Ophelia, and associated him with the 'Zizians', a rationalist-community offshoot described by multiple outlets as cult-like. These are media/encyclopedia characterizations, not primary-source confirmation.Jan 20, 2025
• Completed a Software Developer Internship at Jane Street in 2018, where the role description says he designed and wrote an OCaml/Incr_dom web app to visualize Jane Street's all-purpose data format using lazy loading and partial rendering.2018
• Represented Germany at the International Olympiad in Informatics (IOI) 2014, winning a gold medal with rank 24 and a score of 449/600 (IOI 2014, held 20 Jul 2014).Jul 20, 2014
• The task's caller-supplied identity lead carried a LinkedIn identifier 'taiga-635554606' and a LinkedIn URL for felix-bauckholt; the profile's own enrichment is index-derived (local index), which is not independent primary-source confirmation.Jan 23, 2025
• Studied at the University of Waterloo, earning a Bachelor of Mathematics in Pure Mathematics over 2015-2019 - the standard four-year B.Math degree. This is an index/LinkedIn-derived claim corroborated by press, not a university registrar record.2019
• Worked as an Undergraduate Research Assistant at the University of Waterloo in 2017 on the Stable Marriage Problem with Ties, improving the analysis of a 1.467-approximation algorithm for a special case to 1.444 (index-only claim; the role description cites an arXiv paper).2017
