Extracted from the posting
Senior Compiler Performance Engineer to own end-to-end performance areas of Falcon, the JIT compiler in Azul Platform Prime, built on LLVM. Responsibilities include designing optimizations in the middle and back end (inlining, vectorization, escape analysis, deoptimization, GC barriers) and improving x86_64 and AArch64 code generation. Requires 5+ years of optimizing or JIT compiler experience and strong C++.
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.
