If you have a passion for innovating within a complex network ecosystem, enjoy building scalable systems and documentation structures, and are curious about how AI can refine network operations, this role provides a platform to make a significant impact at Jane Street. We look forward to learning from your expertise and unique perspective.
- Have 7+ years of experience operating and deploying network infrastructure, with 3+ years dedicated to ground-up network design
- Have deep experience with routing and network protocols (OSPF, BGP, PIM-SM), and the troubleshooting of transport protocols (TCP/UDP)
- Comfortable operating in Linux environments and proficient in at least one programming language
- Strongly inclined to automate workflows and explore AI/ML approaches to improve efficiency or reduce overhead
- Eager to produce comprehensive, scalable documentation that benefits the entire team
- Have a demonstrated ability to balance multiple priorities, switch contexts effectively, and maintain a high level of customer service

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.
