When does Hudson River Trading post internships?

HRT posted its summer 2027 Algorithm Development and Software Engineering internships in mid-July 2026, with rolling review. Its January WiTTI internship posted in mid-September with a mid-October deadline.

What internships does HRT offer?

HRT offers summer Algorithm Development (quant research and trading), Software Engineering, and Hardware Engineer internships, plus PhD summer and winter internships. It also runs the WiTTI winter internship and the Inside HRT and Explore HRT spring programs.

Can freshmen or sophomores intern at HRT?

Summer internships are for students a year from graduating, but WiTTI and Inside HRT reach students earlier in their degree. WiTTI is a paid two- to four-week January program in New York for students new to quantitative trading.

What is the HRT interview process?

It starts with a timed online coding test, then about two phone interviews, then a full day of interviews. Algorithm Development candidates also see probability and data analysis questions.

Hudson River Trading internships: when they open and how to apply

At Hudson River Trading, nearly every technical role writes C++ or Python against real market data. Summer internships split into Algorithm Development (quant research and trading) and Software Engineering, and a January internship plus spring programs cover students too early for the summer track.

Internships and programs at Hudson River Trading

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

Algorithm Development (Quant Research & Trading) Internship: Interns apply quantitative research and modeling to understand and predict market behavior, working in C++ and Python. It runs from late May to mid-August in New York, London, and Singapore, with a separate PhD version.
Software Engineering Internship: Interns build real systems behind HRT's trading and research environment in C++ or Python. The summer 2027 posting lists New York, Chicago, Austin, London, and Singapore.
Women in Trading and Technology Internship (WiTTI): A paid two-, three-, or four-week January internship in New York for students curious about quantitative trading but new to it, sized to fit your winter break. Participants do independent programming projects in Python and C++ and see both software engineering and algorithm development. Students who already have relevant internship experience are pointed to the summer programs.
Inside HRT: A three-day spring program in New York for first- and second-year STEM students, with workshops, tech talks, and networking before summer internship eligibility.
Hardware Engineer Internship: A New York internship for students interested in FPGA and hardware design for low-latency trading, recruited alongside HRT's hardware and design verification new grad roles.

When Hudson River Trading posts internships

HRT opens summer internships early. The summer 2027 Algorithm Development and Software Engineering internships went live on July 13, 2026, about ten months before the start date, and review is rolling. The Hardware Engineer internship followed at the end of August. Candidates report four to eight weeks from first contact to offer.

The early programs come later. WiTTI for January 2027 posted in mid-September with an October 16 deadline. Inside HRT and Explore HRT take place in the spring, which gives underclassmen a second window after the summer rush.

Who can apply

Summer internships are for students one year from graduating; the summer 2027 postings are for 2028 graduates. WiTTI asks for full-time undergraduates in a technical or quantitative discipline graduating between fall 2028 and summer 2030, without extensive quant trading experience. Inside HRT is for first- and second-year STEM students, while Explore HRT (New York, London, Singapore) targets the same graduating class as the summer internships.

Degrees in math, physics, computer science, and statistics are typical. Programming experience in C, C++, Python, or Rust helps on every track.

The interview process

HRT's engineering blog describes a timed take-home coding test on HackerRank or Codility, then about two phone interviews (a technical discussion and a programming round), then a full day of back-to-back interviews, virtual or in person. Algorithm Development candidates report added probability, expected value, and data analysis rounds.

HRT says it grades collaboration and teachability along with correctness: whether you use hints and apply ideas from earlier in the interview. Needing hints is fine. Say out loud when you are stuck or switching approaches.

Tips for applying to Hudson River Trading

Get comfortable with C++ or systems-level Python. Memory, performance, and OS knowledge come up more at HRT than at most tech companies.
Read HRT's interview prep post on its HRTBeat blog before the take-home; it lays out exactly what the firm looks for.
Sophomore without quant experience? WiTTI posts in September and closes in October. It is built for students new to the industry.
