Engineers - Internship 2026

OVERVIEW

This internship is for students who want to spend a summer doing real engineering work inside a production trading environment. Interns join one of our engineering teams and ship code that runs in production. There is no shadow work and no sandbox projects.

You will work closely with senior engineers, get direct feedback, and own clearly scoped problems with real impact. We expect interns to think, implement, test, and iterate like full-time engineers.

WHAT YOU WILL WORK ON

Depending on team fit and background, interns are embedded into one of our engineering teams (Tooling, Algo, OTC, or Core Systems) and contribute to carefully scoped engineering projects.

Typical responsibilities include:

- Designing and implementing high-quality internal software in a controlled environment

- Tackling clearly defined, non-trivial engineering problems end-to-end

- Prototyping and validating new technical ideas and approaches

- Studying existing systems and delivering focused, well-reasoned improvements

- Engaging in code reviews and technical discussions with experienced engineers

This is not a research internship and not a learning-only program. You are expected to deliver working software.

WHAT WE EXPECT FROM YOU

- Strong fundamentals in computer science (algorithms, data structures, systems basics)

- Hands-on programming experience outside of coursework (projects, competitions, open source)

- Comfort working in Linux-based environments

- Ability to reason independently and ask precise questions when blocked

- Come up with ideas and solutions for vaguely defined open problems

- Ownership mindset: you take responsibility for finishing what you start

Experience with Rust, Python, TypeScript, or systems programming is a plus, but not required.

WHO THIS INTERNSHIP IS FOR

- Students in Computer Science, Software Engineering, Mathematics, or related fields

- Candidates who are comfortable with open-ended problems and limited initial d...
