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

As a Compiler Performance Engineer, you will help optimize a production-grade Java just-in-time (JIT) compiler to generate faster, more efficient machine code. You will analyze Java benchmarks and real-world enterprise workloads to identify performance bottlenecks and trace them to their root causes within the compiler. Working across the compiler's optimization and code generation layers, you will implement improvements that deliver measurable performance gains. You will collaborate with a distributed team of compiler specialists and contribute to the evolution of a mature compiler built on LLVM. Your work will also include developing tests and benchmarks to validate improvements and prevent regressions. This role offers an chance to apply low-level programming expertise, compiler theory, and hardware knowledge to solve challenging performance problems with direct customer impact.

Accountabilities

•




Analyze Java benchmarks and customer workloads to identify performance gaps in generated machine code and determine their underlying causes within the compiler.

•
Implement and refine compiler optimizations across the middle end and back end, including inlining, loop transformations, vectorization, redundancy elimination, and speculative optimizations.

•
Investigate how compiler optimizations interact with runtime behavior and identify opportunities to improve execution efficiency.

•
Improve machine code generation for x86_64 and AArch64 processor architectures.

•
Evaluate optimization strategies and assess their impact on runtime performance, code quality, and execution efficiency.

•
Develop and maintain tests and benchmarks that demonstrate performance improvements and protect against regressions.

•
Use systematic performance analysis and debugging techniques to investigate com
