Extracted from the posting
Compiler Performance Engineer to find where Falcon, the JIT compiler in Azul Platform Prime (built on LLVM), generates slower code than it should, and fix it in the optimizer and code generator. Work covers inlining, loop optimizations, vectorization, and x86_64 and AArch64 code generation, with tests and benchmarks for each change. Requires C++, SSA and data flow knowledge, and experience reading assembly.
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 Compiler Performance Engineer to make Falcon generate even faster code. This is not a compiler front end role and not a compiler built from scratch: the compiler exists, runs in production at large enterprises, and your job is to find where the generated code is slower than it should be and fix it in the optimizer and code generator.
You will join a distributed team of compiler experts and work on real workloads with direct, measurable impact on customer performance.
