High Performance Computing (HPC) Intern (Summer 2027 - Chicago)

As an HPC Engineer Intern, you’ll work side-by-side with your mentor and teammates to build and optimize the infrastructure that powers a global trading firm. Your projects will be scoped based on real business needs and your mentor will be fully invested in helping you design scalable, high-performance systems that are built to last. You’ll contribute to meaningful projects that support large-scale research, machine learning, and data analysis pipelines, and you’ll see your work drive real impact across trading teams.

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.
