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 direction
Candidates who prefer low bureaucracy, direct feedback, and clear expectations
This internship is open to candidates in their final year of studies, with top-performing interns considered for a full-time position following the internship

Interview process
Online Coding challenge and Technical Quiz
Chat with a recruiter. Consider it an introductory call; there's no need to prepare anything apart from your questions regarding the company, team, culture, and any work-related inquiries.
Technical interview. Live coding task followed by a discussion on experience and background.
We keep the process short and signal-driven.
