Senior Compiler Performance Engineer
Azul, Bangalore +3
About the job
Falcon is the optimizing just in time (JIT) compiler in Azul Platform Prime. It compiles hot Java bytecode into highly optimized machine code and delivers Java performance that standard JVMs do not reach. Falcon is built on LLVM.
We are looking for a Senior Compiler Performance Engineer to own major performance areas of Falcon. This is not a compiler front end role and not a compiler built from scratch: Falcon is mature and runs in production at large enterprises. Your job is to push its generated code further, deciding which optimizations matter, designing them and delivering measurable speedups on real workloads.
You will work in a distributed team of compiler experts, with direct influence on what Falcon optimizes next.
What You Will Do (aka Responsibilities) - Own performance of Falcon for a set of workloads or an optimization area end to end: analysis, design, implementation, validation
- Design and implement new optimizations and improve existing ones in the middle end and back end: inlining heuristics, loop optimizations, vectorization, escape analysis, speculation and deoptimization, GC barrier and runtime call optimization
- Drive code generation quality on x86_64 and AArch64, including bringing Falcon to new hardware platforms
