About the Position
Our goal is to give you a real sense of what it's like to work at Jane Street full time while also providing a truly unparalleled educational experience. As an intern, you are paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done.
As a Network Engineer intern, you’ll work with full-timers to learn how we maintain and improve a critical piece of infrastructure underlying our firm’s technology. Our numerous distributed systems are built on a reliable, multi-vendor network infrastructure that supports all traffic profiles from trading to internet connectivity.
On any given day, we might be:
Working on cross-team projects such as site expansions and new colocation builds
Debugging routing protocols
Provisioning new market data feeds and connections to third parties
Automating support tasks and improving the team's ability to monitor the network
You’ll have a unique opportunity to see how our team interacts with several groups to build 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.
Your internship project might consider big-picture questions that we’re still trying to figure out, or involve building something new. Your mentors will help you understand the range of problems we solve every day, from finding new and interesting ways to resolve production issues quickly, to performing comprehensive root-cause analyses and integrating clean and robust long-term fixes.
