We’re looking for a software engineer who is passionate about front-end development, user-interface design, and typed functional programming. You would take part in the design and implementation of our next-generation of browser-based tools for operating our trading infrastructure.
We’re building for expert users, which means we want to maintain a high UX bar, and at the same time create tools that are flexible and powerful enough to satisfy the needs of deeply engaged users.
Beyond working on the individual tools, we want someone who can find opportunities to create libraries and abstractions that capture common interaction idioms, and to sharpen our development practices and firm-wide approach to UI development.
We’re looking to add someone with a particular mix of skills and experience:
- A strong background in web technologies, including browser fundamentals like CSS and the DOM, and an understanding of the principles of UI frameworks like Vue, Angular, React, and Flutter.
- Practical experience building sophisticated UIs in the browser. We’re looking for someone who loves the detailed polishing that’s needed to build elegant and highly usable UIs.
- An interest in and appreciation of typed functional programming as an approach to UI construction. Experience with languages like Elm, ReasonML, Purescript, and Typescript is a plus. (we don’t expect experience in OCaml in particular.)
The role will provide opportunities to work in multiple parts of the stack, including front-ends, back-ends, middleware, and databases. The job will also involve working closely with traders and other end-users to better understand their needs.

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.
