• Quant employment verification: CONFIRMED. Declan Gorey holds an actual employee role (not a student program, insight day, or incoming offer) at Optiver, a proprietary market-maker in exchange-traded derivatives (+ quantitative trading). Evidence: (1) FINRA BrokerCheck individual record #8275843 is a primary regulatory filing that lists his employment with Optiver US LLC; (2) the roles shown on his LinkedIn profile (Equity Derivatives Trader, Optiver, Amsterdam, 2016-2020; Commodity Derivatives Trader, Optiver, London, 2021-present) are consistent with that filing. Identity is supported by the IMO 2011 participant record (Australia) under the same name together with University of Cambridge mathematics education. Employer classification: Optiver is a listed-derivatives market-maker/prop trading firm, i.e. an actual quantitative-finance employer, not a company whose name merely contains 'quant'. Scope note: the specific role dates are taken from LinkedIn (index-derived enrichment), so the exact date boundaries should be treated as index-only; the existence of the role is independently corroborated by the regulatory filing.Sep 17, 2026
