Trading Desk Operations Engineer Intern

About the position

Trading Desk Operations Engineers (TDOEs) keep our trading desks running. On a given day, a TDOE might investigate an outage in a critical system, write code, often with AI tools, to automate an error-prone process, or sit with a trader to build a dashboard together. The job is a balance between steadily making workflows and systems more resilient and meeting the urgent needs of trading.

Our TDOE internship is an immersive program built around real-world projects directly tied to the challenges we face on the desk every day, all guided by dedicated TDOE mentors. The summer has three main parts:

• Bootcamp: You’ll start with two weeks of classes on the technologies we use on the desk and the basics of market making. Our introductory programming curriculum covers languages from Bash to OCaml, and no prior experience is required. Classes on the products we trade and the tools we use continue well past bootcamp.  
• Projects: You’ll work on several projects with different mentors. Recent interns built a tool that flags discrepancies between our records of voice trades and the public tape, implemented a new exchange order type after working through two exchanges' conflicting rulebooks, and built a UI showing when ETFs can be traded and settled around holidays in dozens of markets. Many intern tools reach daily use on the desk. 
• Operations: Alongside your projects, you'll take support rotations and handle the kinds of requests TDOEs field every day. They range from fixing a script that didn't run to pulling data a trader needs before earnings. You'll also support a simulated trading portfolio, building your own tools to book its trades, check its positions, and follow each trade through its life cycle. 

Our goal is to give you a real sense of what it's like to work at Jane Street full time while providing an unparalleled educational experience.

We can't wait to teach you what we know, and learn a few things from you as well!
