Jane Street

About the Position

As a Linux Engineering intern, you’ll work side by side with full-timers to learn how we maintain and improve the critical infrastructure underlying our firm’s technology, including our production trading systems. On any given day, we might be debugging kernel performance, developing management tools, or resolving production issues in real time. Our mix of in-house and open source software allows us to investigate and innovate at every level.

During the program you’ll work on up to two projects, mentored closely by the full-time employees who designed them. Some projects consider big-picture questions that we’re still trying to figure out, while others involve building something new.  We will choose your projects so you’ll gain a better understanding of the wide range of problems we solve every day — from finding new and interesting ways to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way.

You’ll have a unique opportunity to see how our team interacts with almost every other group, building solutions that work on a firm-wide scale. We automate as much of our work as we can, because we find that automation reduces our error rate and overall workload — plus, we think it's fun.

About You

We don’t expect you to have a background in one specific field — we’re looking for smart people who enjoy solving interesting problems. We’re more interested in how you think and learn than what you currently know. You should be:

• Knowledgeable of operating system fundamentals and computer architecture
• Able to understand network protocols at a basic level
• Someone who solves problems by writing code (in any language)
• Intellectually curious, collaborative, and eager to learn
• Humble and unafraid to ask questions and admit mistakes
• A strong communicator
• Are comfortable at the command-line of a *nix machine as you are in a GUI
• Experienced with systems programming concepts like C, sockets, virtual memory, and the process life cycle
• Experienced with a modern *nix system, whether that’s from course work, time spent as a systems administrator for your campus computer lab, side projects, etc.
• Intending to start full-time employment in 2027 or 2028
• Fluent in English

Please note: Jane Street will provide flights to and from Hong Kong as well as accommodation throughout the entirety of the program.
