As a Software Engineer Intern, you'll work side-by-side with your mentor and teammates to build real-world applications that power a global trading firm. Your projects will be scoped based on your team's real needs - not hypothetical tasks - and your mentor will be fully invested in helping you build high-quality software that's designed to last. You'll contribute to meaningful projects solving trading problems and improving the performance, reliability, and scalability of our systems - and you'll see your code hit production in real time.

We operate in one of the most fast-paced and competitive environments in the tech industry. That means no two days are the same, and every day brings new, exciting technical challenges to solve.
