• Quant employment verification: CONFIRMED. Omar Obeya held paid software-engineering roles at Two Sigma, a systematic quantitative hedge fund / investment manager, including full-time Software Engineer (2019-2023) and two SWE internships (2018, options market making; 2017, databases), and later a Software Engineer role at Hidden Road, a prime brokerage serving trading firms. The Two Sigma roles are actual employment/internships (not camps, insight days or offers), and identity is corroborated by the IOI-2013-Egypt anchor, MIT degree, and matching New York software-engineering trajectory. Employer check: Two Sigma is a quantitative/systematic investment manager (Wikipedia; company site); Hidden Road is a FINRA-registered prime broker/broker-dealer, i.e. a trading-services firm, not itself a quant fund.Aug 1, 2019
• Software Engineer at Two Sigma (Aug 2019 - 2023) delivering market-data feeds reliably and efficiently in C and Python - the full-time role that followed his two Two Sigma internships.Aug 1, 2019
• Two Sigma SWE Intern - Options Market Making (summer 2018): re-designed a news-feed receiver server into a client library to remove server/client communication overhead; this is an internship inside Two Sigma's options market-making business, the clearest quant-finance role on the record.Jun 1, 2018
• Won a bronze medal representing Egypt at the International Olympiad in Informatics 2013 (rank 130, score 257/600).Jul 13, 2013
• Software Engineer | Billing - Core Team at Hidden Road (2023-2025), leading scaling of a real-time usage-based billing system (Python, PostgreSQL, Snowflake, SQL, AWS); Hidden Road is a prime brokerage serving trading/hedge-fund clients, so this is trading-infrastructure work adjacent to but distinct from a quant-.research role.Jan 1, 2023
• Published '[contact omitted]' as his MIT contact on the SuperUROP scholar page - a public, MIT-issued email, not a guessed address.Jan 1, 2018
• Two Sigma SWE Internship - Databases (summer 2017): built a framework converting the in-house row-oriented storage format to Apache Parquet and Apache ORC for comparison.May 1, 2017
• Hidden Road, his most recent employer, was acquired by Ripple for $1.25B (announced April 2025), confirming it as a real, significant trading-services firm rather than a name-alike.Apr 8, 2025
• Timeline read: three consecutive Two Sigma stints (2017 intern, 2018 intern, 2019-2023 full-time) followed by a move to Hidden Road (2023) - a single-employer early career at one quant firm, then a shift into trading infrastructure at a prime brokerage.Aug 1, 2023
• Research Assistant at MIT CSAIL (2018-2019) under Prof. Julian Shun, designing the first work-efficient parallel in-place radix sort and first-authoring/presenting the resulting paper; he is listed among Shun's alumni.Jun 1, 2019
• First-authored 'Theoretically-Efficient and Practical Parallel In-Place Radix Sorting' (SPAA 2019) and co-authored 'Parallel In-Place Algorithms: Theory and Practice' (2021) and work on parallel in-place shuffling (SEA 2023); Google Scholar shows 75 citations, h-index 2.Jun 1, 2019
• B.S. in Computer Science, MIT (2014-2018) and M.Eng., MIT (2018-2019); the MEng year overlaps his CSAIL research assistantship.Jun 1, 2018
