As a Technical Operations Intern, you will join a team responsible for the internal tools and systems that enable daily trading and operational workflows. Early in the internship, you’ll learn how our Ops and Trading teams use internal applications, how production support works in a trading environment, and the standards we use to keep critical tools reliable. You’ll then take ownership of a modernization project for a production web portal used daily by operations staff and traders.

This internship will begin in June 2026 and last 10 weeks. We are considering candidates that are graduating between December 2026 up until August 2027 or recent graduates. This position will require in-person presence in our Chicago office located in River West right next to the Merchandise Mart and convenient to public transportation.

Position Overview

We are seeking highly motivated individuals to participate in a summer program in which they will plan and execute a project that modernizes a legacy internal web tool (“OpsWeb”). The project focuses on improving maintainability, usability, and reliability while partnering with daily end users to ensure changes are practical and non-disruptive.

Goals

• Deliver a measurable improvement to a production internal application used daily
• Learn to refactor legacy systems without disrupting critical workflows
• Build strong habits around code quality, incremental rollout, stakeholder feedback, and documentation

• Experience with Python required, JavaScript/TypeScript and C# would be nice to have (web development experience is a plus)
• Familiarity with basic web concepts (HTTP methods like GET/POST, HTML/CSS)
