SPs are versatile generalists who take a deeply analytical and strategic approach to solving Jane Street's most pressing problems. They move across groups as firm priorities evolve, developing a holistic view of our business and driving cross-functional growth. Most SP careers start with a year-long set of rotations across the entirety of Jane Street's business-including trading, technology, finance, compliance, operations, and more. The rotations help new SPs develop a broadened skill set, strong cross-group connections, and a detailed understanding of how all the pieces of our business fit together. This central foundation prepares an SP to take ownership over strategic efforts, both within their team and in cross-functional initiatives. While the rotational year ends with a "permanent" group placement, SPs often move teams throughout their careers as their interests and the firm's priorities shift. This ultimately allows successful SPs to take an increasingly central role in shaping our business.

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.
