About the role

Java Runtime-focused role at Amazon Corretto within the ASBX group. Work on compilers, garbage collection, and runtime optimizations for OpenJDK, contributing upstream to OpenJDK and Corretto, with emphasis on performance, scalability, and cross-architecture tuning (x86 and Graviton).

Responsibilities

  • Identify areas for improvement using data from real running services, and turn those findings into concrete compiler, GC, and runtime optimizations.
  • Design, implement, and benchmark improvements to JIT compilation, garbage collection, and core runtime subsystems in the OpenJDK compiler, runtime, and libraries.
  • Contribute your changes upstream to OpenJDK and to Amazon Corretto, working through code review and the community process.
  • Tune runtime behavior for performance and efficiency across x86 and Graviton (AArch64) architectures.
  • Build profiling, observability, and auto-tuning tooling so runtime expertise scales across the fleet.
  • Share your findings with the engineering community and help service teams adopt runtime improvements and newer JDK versions

Qualifications

  • Compiler backend or optimization experience — instruction selection, register allocation, code generation, escape analysis, inlining, or intrinsics
