Old Mission

Old Mission's current openings include a 2027 Graduate Program and a 2027 Internship Program, both aimed at students and recent graduates:

• Quantitative Trader, 2027 Graduate Program: August start in Chicago, New York, or London; a separate February-start cohort in Chicago or New York
• Quantitative Researcher (Ph.D.), 2027 Graduate Program: Chicago, August start
• Software Engineer, 2027 Graduate Program: Chicago, August start
• Software Engineer, 2027 Internship Program: Chicago, June start; a summer internship building C++ trading tools, with corporate housing provided

A candidate targeting the Quantitative Trader track alone is tracking two separate start-date cohorts at this one firm; the summer internship runs on a third, earlier clock. That is three application timelines to hold in view before weighing any other firm's calendar.

Old Mission entered the ETF market in 2008 and has operated as an ETF and ADR market maker since, providing on-screen liquidity and direct quotes to institutional clients. It trades only its own capital and takes no outside investment, a structure the firm says lets it invest directly in its own team rather than in managing client money. It runs from three offices, Chicago, New York, and London. For an early-career applicant this is a narrower bet than a multi-strategy fund or a bulge-bracket bank: the work sits inside market-making and derivative pricing rather than spread across banking, research, and asset-management divisions, which suits someone who already wants that specific seat rather than a rotational look across businesses.
