About Hudson River Trading

Hudson River Trading is a research-driven trading firm that builds complex algorithms to make trades on the financial market. They combine software engineering, statistics, and finance to create systems that react in milliseconds. This isn’t stock trading the way you see in movies with phones ringing and people yelling. This is about automation, machine learning, and optimizing performance down to the microsecond. Their teams are filled with quants, software engineers, algorithm developers, and systems experts all working together to solve ridiculously complex problems in a competitive space.

Founded in 2002, the company has grown massively and now operates in multiple cities, including New York, London, Singapore, and Austin. Inside HRT, you’ll find small, collaborative teams that work across disciplines, from core engineering to low-latency trading systems. What sets them apart isn’t just the tech or the pay but the way they combine deep mathematical research with real-time systems to create results. Whether it’s optimizing infrastructure or optimizing an algorithm to decrease processing time, their work is fast, precise, and super technical.

Internship Overview

Interns at this company don’t just play around with sample problems or test environments. They work on the same systems, codebases, and challenges as full-time employees. The trading internship at Hudson River is designed to introduce students to real-world challenges, projects and software tasks that push them to think fast and build smart. Depending on your track, you might be working on internal trading tools, analyzing performance metrics, or coding new features for the core system. Tracks are typically split into software engineering, algorithm development, and systems roles. It’s one of the few programs where interns genuinely get to see how their work performs in production-level setups.

The internship typically runs for twelve weeks during the summer, and the application window usually opens in late summer or early fall the year before. Interns join small teams where they code alongside experienced developers, participate in meetings, and contribute directly to problem-solving sessions. The environment is intense but structured in a way that encourages questions, feedback, and deep learning. If you’ve done internships before that felt more like school projects than actual work, this one’s a whole different experience. You’ll be paired with mentors, given real problems to solve, and pushed to think critically, all while being treated as a legitimate part of the engineering or research team from day one.

Popular Roles for Interns

The internship experience at Hudson River Trading isn’t the same for everyone, and that’s honestly what makes it so authentic. Whether you’re into building systems that run at lightning speed, writing algorithms that process huge amounts of data, or making sure operations work effectively, there’s probably a spot that fits exactly what you’re good at. These roles aren’t just placeholders or side projects either, since interns actually step into real responsibilities with real teams.

Software Engineer Intern

This one is probably the most popular of all. Unlike other interns, a Hudson River Trading software engineer doesn’t just observe from the sidelines or clean up random files. You actually get to work with the real codebase, the real engineers, and the real systems that are used in production. Interns are paired with full-timers who’ve been building low-latency, high-performance stuff for years, and the pace is fast but super rewarding. Whether you’re helping optimize systems or building tools that traders rely on, your work actually matters. You’re not stuck on intern projects but writing code that’s tested, reviewed, and sometimes shipped. That’s what makes the HRT SWE intern role feel like more than just a summer job.

  • Work with C++, Python, and other low-level languages
  • Contribute to real systems used in live trading environments
