Jane Street Internships (Trading, Research & Software)

Jane Street’s internships in quantitative trading, research and software engineering are among the most sought-after student programs in the world, pairing famously high compensation and housing support with a genuinely teaching-first culture. Interns rotate through real desks and codebases in New York, London, Hong Kong, Singapore or Amsterdam, learning markets from scratch through classes, mock trading and close mentorship.

No finance background is expected; probability, algorithmic thinking and problem-solving depth decide the interviews. Applications open extremely early (often more than a year ahead) and run rolling, and dedicated programs for first and second-year students feed the pipeline.

• Undergraduate, master's and PhD students with exceptional quantitative ability; most successful applicants have strong backgrounds in mathematics, computer science, statistics or physics.
• Roles include quantitative trading, quantitative research, software engineering, and specialized tracks like strategy and product.
• No finance knowledge is required or expected; Jane Street explicitly teaches markets from scratch.
• Problem-solving depth matters far more than credentials: math olympiad, competitive programming and research backgrounds thrive.
• Software roles value functional programming curiosity (the firm famously uses OCaml), though any strong language is fine for interviews.
• Work authorization support is provided across its New York, London, Hong Kong, Singapore and Amsterdam offices.
• First and second-year students can enter through dedicated early-insight programs (such as FTTP and INSIGHT) that feed the internship.

• Rotate through desks or teams working on real trading, research or engineering problems with production impact.
• Trading interns learn market-making through classes, mock trading and live desk work with close mentorship.
• Software interns ship code into the firm's systems, from tooling to trading infrastructure.
• Attend the internal education program covering probability, markets and technology, taught by practitioners.
• Work through open-ended projects where your reasoning is evaluated more than polish.
• Present your work and receive a rigorous end-of-internship evaluation for return offers.

• Widely reported as some of the highest internship compensation in the world, with housing support in hosting cities.
• Teaching-first culture: structured classes, games and mentorship rather than sink-or-swim.
• High conversion into full-time trading, research and engineering roles.
• Offices in New York, London, Hong Kong, Singapore and Amsterdam broaden geographic options.
• Early programs for first and second-year students create a multi-year pipeline.
• A puzzle-loving culture famous for its games, estimathons and math outreach.

• Apply directly on the Jane Street internships page; applications for each summer open very early (often from late spring a year ahead) and are reviewed on a rolling basis.
• Choose the role honestly matched to your strengths: trading and research interviews test probability, expected value and mental math, while software interviews test algorithms and systems reasoning.
• No CV keyword games needed, but competition results and hard projects stand out.
• Expect several rounds of increasingly deep problem-solving interviews, often starting with an online assessment.
• Prepare with probability puzzles and past interview-style questions for months, not days.
• First and second-year students should apply to the early-insight programs, which fast-track later internship offers.
