Linux Engineer

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'll be paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done. As a Linux Engineering intern, you'll work side by side with full-timers to learn how we build and maintain the critical infrastructure underlying our firm's technology, including our production trading systems. Our work is hugely varied, both in the technical areas we work on and the ways we work. However, a consistent theme is that we typically work closer to the operating system layer, and sometimes dive as deep as the firmware or physical hardware layer. On any given day, we might be chasing a performance issue from the application layer all the way to the hardware, fixing a kernel bug, responding to an overheating datacenter in real time, analyzing data to improve the predictiveness of our monitoring systems, or building robust automation to tackle a previously manual workflow. Our purposeful blending of in-house and open source software allows us to investigate and innovate at every level. During the program you'll spend the majority of your time working on a project, mentored closely by the full-time employees who designed it. Each project is carefully picked to challenge and develop both your in-depth understanding of Linux systems and your software engineering skills, both while delivering real value that is relevant to the challenges the firm is facing right now. Past projects have touched on a broad range of areas, including: investigating the resilience of different file system implementations at scale, automating the collection of diagnostic information from early boot failures, designing a scalable system for collecting extremely fine-grained TCP diagnostic data, or extending our infrastructure provisioning and management systems to support
