As the only company focused 100% on Java, Azul is building the Java platform for the modern cloud enterprise. We are reimagining how customers use Java, bringing them the tools and insight they need to deliver faster, more performant, more dependable, and less expensive Java services. Come join one of the most influential members of the Java and OpenJDK community and help influence the future of Java.
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 Staff Compiler Performance Engineer to set the technical direction for Falcon performance. 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. You will decide where the next significant performance gains come from, lead the design of the optimizations that deliver them, and make sure the compiler architecture supports the product roadmap.
You will be the senior technical voice on a distributed team of compiler experts and a key partner for runtime, GC and product teams.
What You Will Do
- Define the performance strategy for Falcon: identify the largest opportunities across benchmarks and customer workloads and turn them into a technical roadmap
- Lead design of complex, cross cutting optimizations in the optimizer and code generator, and of the interfaces between the compiler, the runtime and the garbage collector
- Make architectural decisions on the Falcon optimization pipeline, compile time budget and tiering strategy
- Lead enablement of Falcon on new hardware platforms and new Azul products
- Mentor senior engineers, review critical designs and code, and set standards for performance methodology and validation
- Represent Azul in the LLVM community: drive upstream design discussions and contributions that benefit managed language compilers
Minimum Requirements
- 8+ years of professional experience developing optimizing compilers or JIT compilers
- Track record of technical leadership: owning the design of major compiler components or optimization frameworks used in production
- Expert C++ skills and experience in large, long lived codebases
- Deep expertise in compiler optimization and code generation, with a clear view of the tradeoffs between peak performance, compile time, warmup and code size
- Expert performance analysis skills down to the microarchitecture level
Nice to Have
- Recognized contributions to LLVM or another major compiler: code owner, maintainer or author of significant upstream work
- Deep experience with JIT compilers for managed languages: HotSpot C2, Graal, V8, .NET RyuJIT or similar
- Experience working closely with runtime and GC teams on speculation, deoptimization and barrier design
What We Offer
- Opportunity to make a high impact at a growing, global company
- Work alongside top experts worldwide contributing to the Java ecosystem
- Referral Program — help us grow with great people
- Premium IT equipment — MacBook Pro or hardware of your choice
- Competitive paid holidays and sick time
- Flexible working hours
- Remote first OR Prague / Limassol / Belgrade city center offices OR hybrid - UP TO YOU!
- Competitive compensation
