• Quant employment verification: CONFIRMED. Two Sigma Securities, LLC - the broker-dealer arm of Two Sigma, a quantitative investment management and systematic trading firm (~$75B AUM) - employed Junbin Teng as a Software Engineer from 12/2016 to 02/2019, per his FINRA BrokerCheck registration (CRD# 6513877), a regulatory filing rather than a self-reported profile. That is an actual paid engineering role at a firm whose core business is quantitative trading, and the identity is independently anchored (IOI 1997 Singapore bronze medalist; NUS Computer Engineering; New York). Index-derived LinkedIn data additionally lists a Core Developer role at Hudson River Trading (also a quantitative trading firm) and a Software Engineer role at Google; the HRT entry is index-only and treated as the most recent known role, not confirmed current employment. Student programs, competitions and camps are excluded from this count.Feb 1, 2019
• Identity cross-check: the IOI statistics database (stats.ioinformatics.org/people/1193) lists 'Teng Junbin' as a Singapore IOI contestant with exactly one bronze medal, matching CPHOF's record (IOI 1997, rank 64) - the name, country and medal align, supporting that the Olympiad identity and the engineer are the same person.Dec 7, 1997
• Index-only careeer timeline: Software Engineer at Two Sigma (confirmed 12/2016-02/2019 via FINRA), Software Engineer at Google, then Core Developer at Hudson River Trading (indexed start 2022-08). The caller lead gives an HRT end of 2026-01, but the index itself does not state an end date, so HRT is recorded as last-known, not current.
• Education: Honors 1st class, Computer Engineering, National University of Singapore, per LinkedIn index data - a plausible Malaysia/Singapore pipeline for the 1997 IOI Singapore team, though the degree dates are not published.
• Authored LinkedIn post 'Designing a SystemVerilog Language Server' (activity 7024180183679008768), tagged to a Hudson River Trading job - indicates hands-on hardware/EDA tooling work (SystemVerilog language server) in his HRT engineering tenure; the post content is not accessible without login, so this rests on the indexed post title.
• Authored LinkedIn post referencing an app 'that I've invested in' (financial-knowledge app; activity 7071125272405635072) - signals personal angel/early-stage investing activity, distinct from his engineering roles.
