Job Description

About the Position

We're looking to hire a Software Engineer with experience working on programming languages. Our team maintains a framework used at Jane Street for a wide variety of purposes, including financial modeling, risk calculation, and custom alerting. Our system evaluates, in real time and in parallel, a large, irregular, and dynamic graph of calculations, described in a custom ML-like programming language.

This role focuses on improving and maintaining the language and surrounding ecosystem through a wide range of areas: core language features, standard library management, editor integrations, and more. The language is widely used for critical firm functions, yet offers substantial opportunity for extension and improvement. You should be able to balance the work of understanding and supporting existing uses, as well as organizing and driving new functionality.
