We are looking for Linux Engineers to join the team that maintains the critical infrastructure underlying the rest of Jane Street’s technology. Our group includes hard-working Systems Engineers, Administrators and Programmers, tasked with maintaining and improving the platform that powers Jane Street's production trading systems. Our mix of in-house and open source software allows you to investigate and innovate at every level. On any given day, you could be debugging kernel performance, developing management tools, or resolving production issues in real time. Diving into tricky systems problems is our specialty.
Deployment automation, scalable configuration management, and obsessive monitoring are the focus of some of our ongoing projects. We automate as much of our work as we can, but not because we’re lazy. We find that automation reduces our error rate and overall workload - plus, we think it's fun.
Working in our group provides opportunities for involvement with almost every other facet of the company. We work directly with colleagues in trading, technology, and operations to build and maintain systems with a firm-wide scope. Using feedback from other groups and our custom monitoring tools, we strive to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way.
We don't expect you to come in with deep experience - we're happy to hire smart problem solvers and teach them what they need to know. You’ll train alongside our more seasoned team members in a hands-on capacity, learning how we make tangible and immediate improvements to our infrastructure every day.
About You- Bachelor's degree in Computer Science, Software Engineering, or other technical discipline, or equivalent experience
- Experience managing/troubleshooting Linux systems in a home, work, or school environment
- Exposure to Linux environments through past experience in either software development, IT operations (Helpdesk, Technical Support, DevOps, etc.), or a similar field
- Interested in systems programming and administration and a desire to expand these skills
- Willing to learn OCaml, our programming language of choice (no prior experience with OCaml is required, though)
- Able to analyze and deconstruct technical problems
- Knowledgeable about operating system fundamentals, especially Linux
- Confident with the Unix command line and basic shell scripting
- Has a basic understanding of network protocols and can perform basic troubleshooting
- Comfortable with fundamental programming concepts
- Practical experience with modern Linux systems and systems programming concepts (e.g., C, sockets, virtual memory, process life cycle)
- Intermediate/advanced knowledge of troubleshooting tools and techniques (e.g., gdb, perf, DTrace, or SystemTap) is a plus
- Intermediate/advanced programming experience in any language is a plus
- Intending to start full-time employment in 2025

What We Do
Jane Street works differently. As a liquidity provider and market maker, we trade on more than 200 trading venues across 45 countries and help form the backbone of global markets. Our approach is rooted in technology and rigorous quantitative analysis, but our success is driven by our people.
Our bright, beautiful offices in the heart of New York, London, Hong Kong, and Amsterdam are open and buzzing with conversation. We come from many backgrounds and encourage travel between offices to share perspectives. Some of our best ideas come from bumping into a visiting colleague at the office coffee bar.
Markets move fast. Staying competitive as we’ve grown has required constant invention—of new trading strategies, technology, and processes. We’ve found this is easier when you hire humble, kind people. They tend to help each other, and prioritize teamwork over titles.
We invest heavily in teaching and training. There’s a library and a classroom in every office, because deepening your understanding of something is considered real work. Guest lectures, classes, and conferences round out the intellectual exchanges that happen every day.
People grow into long careers at Jane Street because there are always new and interesting problems to solve, systems to build, and theories to test. More than twenty years after our founding, it still feels like we’re just getting started.
