Remote Mid APAC Artificial Intelligence Oil & Gas Test Engineer Programmer Assembly Java Scala Kotlin

Requirements

• 2+ years of professional experience in compilers, JIT compilers or low level performance engineering • Solid understanding of compiler optimization theory: SSA, data flow analysis, loop transformations • Ability to read assembly and reason about why one instruction sequence is faster than another • Experience with LLVM IR and LLVM optimization passes, or with another optimizing compiler such as HotSpot C2, Graal, GCC or V8 • Experience with profilers such as perf, VTune or async profiler • Knowledge of x86_64 and/or AArch64 microarchitecture • Experience with Java, Scala or Kotlin, or with JVM internals • MSc or PhD in Computer Science with a compiler or performance focus • We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.

Responsibilities

• Analyze performance of Java benchmarks and customer workloads, find gaps in generated code and trace them to their root cause in the compiler • Implement and improve optimizations in Falcon's middle end and back end: inlining, loop optimizations, vectorization, redundancy elimination, speculative optimizations and their interaction with the runtime • Improve code generation for x86_64 and AArch64 • Write tests and benchmarks that prove the improvement and protect it from regressions • Contribute changes upstream to LLVM where it makes sense
