Internships and programs at Susquehanna (SIG)

The early-career programs it runs for students and recent graduates, by the names it uses for them.

Quantitative Trader Internship: SIG's flagship summer internship, based mainly in Bala Cynwyd, with versions in other offices such as New York. Interns split their day between a trading desk, working next to a trader who mentors them, and classes on options theory, decision science, and mock trading taught by traders dedicated to education. Poker hand analysis is part of the curriculum.
Quantitative Research Internship: Research internships in the systematic trading area, with separate postings for master's students. Interns work on data-driven modeling for SIG's systematic and semi-systematic strategies.
Quantitative Strategy Developer Internship: A Bala Cynwyd internship that sits between trading and software, building the tools and strategy code traders use. It suits strong programmers who are also drawn to markets.
Discovery Programs: Introductory programs for students too early for internships, including a First Year Discovery Event and a Quantitative Trading Discovery Day. Participants learn how SIG's trading, technology, and research teams work together through panels, meet and greets, and interactive trading games.

When Susquehanna (SIG) posts internships

SIG is one of the first to post. The summer 2027 Quantitative Trader Internship went up in late May 2026, a full year ahead, and review is rolling, with much of the interviewing done by early fall.

Discovery programs run on a separate calendar aimed at underclassmen, with postings for different offices and class years spread across the school year. First- and second-years should check the Discovery listings once classes start.

Who can apply

Summer internships are for students roughly a year from graduation; each posting states the graduation window. Discovery programs target first- and second-years in fields like math, computer science, engineering, finance, economics, or information systems.

SIG does not expect prior finance knowledge; the education program teaches options and market making from scratch. Most internships are at the Bala Cynwyd campus.

The interview process

Candidates report a short timed quantitative assessment, then a phone screen with probability questions, then a longer technical video interview and a final round combining technical and fit interviews.

Expect decision-making questions framed as games: expected value, betting, and when to take or pass on a bet. SIG's interest in poker is real, and interviewers probe how you reason about risk more than whether you can recite formulas.

Tips for applying to Susquehanna (SIG)

Practice expected-value and betting problems out loud. SIG cares about how you size a decision under uncertainty.
First- and second-years: watch the Discovery listings. They are the firm's designated entry point for underclassmen.
Learn basic options vocabulary before the final round. You do not need it to apply, but it shows real interest in what SIG does.
