Jane Street is a quantitative trading firm with a focus on technology, a scientific approach, and a deep understanding of the markets. We are a global liquidity provider and market maker, operating around the clock and around the globe, employing people in our offices in New York, London, Hong Kong and Amsterdam.
The markets change rapidly, and we need to change faster still. Every day, we come to work with new problems to solve, new systems to build, and new theories to test. Technology is at the core of how we approach that work and developers are intimately tied in to every area of the business.
We are big believers in functional programming, using OCaml, a statically-typed functional programming language, as our primary development language. We also believe in the value of open source software, using it in our daily work and releasing hundreds of thousands of lines of our own code as open source.
As Jane Street grows, the quality of the development tools we use matters more and more. We increasingly work on the OCaml compiler itself: adding useful language features, fine-tuning the type system and improving the performance of the generated code. Alongside this, we also work on the surrounding toolchain, developing new tools for profiling, debugging, documentation and build automation.
We're looking to hire a developer with experience working on compilers to join us. That experience might be from working on a production compiler in industry or from working on research compilers in an academic setting. No previous experience with OCaml or functional programming languages is required.
