Language and Runtime Engineer

We’re looking to hire a Software Engineer with experience working on language compilers and runtimes. 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 user-specified computations. We are particularly focused on understanding, quantifying, and improving its performance and scalability. The technical problems we face relate to implementation of programming languages and their runtimes, efficient distribution and scheduling of computation graphs, and effective measurement and communication of resource usage.

• You have a background in compilers, scheduling, dynamic graph systems, parallel runtimes, or another related field
• You have strong experience in performance analysis and optimization
• No previous experience with OCaml or functional programming languages is required
