Senior Compiler Performance Engineer

About the role

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.

What you'll do

• Work in a distributed team of compiler experts, with direct influence on what Falcon optimizes next
• 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
• Drive code generation quality on x86_64 and AArch64, including bringing Falcon to new hardware platforms
• Investigate complex performance issues reported by customers and turn findings into compiler improvements

What you need

• 5–9 yrs of experience
• Hardware
• Java
• C++
• PhD

Good to have

• .NET
