This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Compiler Performance Engineer based in India.

As a Senior Compiler Performance Engineer, you will drive the performance evolution of a mature, production-grade Java just-in-time (JIT) compiler built on LLVM. You will take ownership of major optimization areas, identifying opportunities to improve generated machine code and delivering measurable speedups across real-world enterprise workloads. Working within a distributed team of compiler specialists, you will influence optimization priorities and help advance the capabilities of a high-performance Java runtime platform. Your work will span compiler middle-end and back-end optimizations, code generation, and support for contemporary processor architectures. You will also investigate complex customer performance issues, contribute to upstream compiler development, and mentor fellow engineers. This role offers the opportunity to solve challenging systems-level problems where compiler theory, hardware knowledge,



and rigorous performance analysis directly impact production performance.
