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.

Yes. Old Mission has 17 student and graduate roles open right now, in summer internships, off-cycle internships and graduate jobs.

Old Mission opened its summer internships on 15 Jul 2026, its off-cycle internships on 24 Jun 2026, its graduate jobs on 5 Jun 2026 and its industrial placements on 6 Aug 2026. Dates are when the firm posted each programme, or when we first saw it on the firm's careers site.

Old Mission has student and graduate roles open in Chicago, London and New York.

Applications to Old Mission go through the firm's own careers site, one application per posting, each expecting a CV and cover letter written for that role.
