At Jane Street, trading, research, and machine learning roles combine to form a collaborative quantitative team. These teams work together to develop the mathematical models and automated trading strategies that drive our business.
Our researchers and ML specialists develop novel models and approaches, implementing them in code to form the core of our systematic models. They analyze large datasets using a variety of machine learning techniques, exploring the latest theory and pushing beyond existing performance limits. Their work spans from optimizing hardware for high-performance computing to building robust platforms that enable others to develop and deploy new strategies efficiently. Their research tackles problems ranging from sub-microsecond trading to uncovering long-term market inefficiencies across trillions of historic events.
Traders focus on enhancing these models, analyzing their performance, and identifying new opportunities for optimization and automation. While some opportunities require rapid decision-making, the majority of our trading is fully automated. Traders leverage their quantitative skills to continually improve and scale our strategies.

Our Technology team designs and builds the systems that run our firm and the tools that our clients and employees use.
We build the physical network and server infrastructure in our offices and data centers, and maintain a scalable and
reliable platform for our trading floors and computing environments worldwide. There’s no specific checklist required to
join this team; we’re more interested in technical depth and intellectual humility than in any particular tool or
language. (Most engineers here arrived without practical experience in OCaml or finance.) We have a wide range of
backgrounds across industry and academia, covering everything from machine learning and programmable hardware to systems
administration, network engineering, compiler design, and a lot more. Join this team to immerse yourself among talented
colleagues in a technically rich environment with no shortage of interesting
problems.

who are dedicated to keeping the firm safe. The scope of our work is
wide-ranging and touches everything from software engineering and DevOps to risk

exposure to different types of work. While we’re the last line of defense, we’re
certainly not the first—employee education is a top priority to make sure
everyone is doing their part to protect our systems and networks. Our colleagues
tend to appreciate technical detail more than most, which makes our job easier
and more fun.

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. The rotation year ends with a ‘permanent’ group placement, but SPs often move across teams
throughout their careers as markets evolve and firm priorities shift. Ultimately, successful SPs take an increasingly
central role in shaping our business.
