Compiler Engineer

extend compiler frontends, IR passes, and backends

You’re a great fit if you:

• Have a strong background in

  computer science, systems programming, or compiler engineering

  .
• Are proficient in

  C and C++

  , with hands-on experience in compiler development.
• Are skilled in frameworks like

  LLVM/Clang, GCC, and MLIR

  .
• Understand

  IR transformations, codegen, vectorization, and LTO

  .
• Are comfortable with build systems (

  Make, CMake

  ) and debugging tools (

  ASAN/UBSAN, GDB, Valgrind

  ).
• Care deeply about performance, correctness, and reliability at the systems level.
• Are curious about how compiler technology accelerates

  AI, scientific computing, and large-scale applications

  .

Primary Goal of This Role

To design and implement new compiler features and optimizations across frontends, IR, and backends, enabling faster, more reliable execution of cutting-edge applications.

What You’ll Do

• Extend compiler

  frontends, IR passes, and backends

  for new features and optimizations.
• Optimize

  code generation, vectorization, and link-time execution

  across architectures.
• Debug and validate compiler pipelines using

  ASAN/UBSAN, GDB, and Valgrind

  .
• Collaborate with researchers and engineers to adapt compilers for

  AI and high-performance workloads

  .
• Maintain build systems and workflows with

  Make/CMake

  .
• Ensure that compiler optimizations balance

  performance, correctness, and maintainability

  .

Why This Role Is Exciting

• You’ll work at the core of

  systems and compiler innovation

  .
• You’ll push the limits of

  performance and optimization

  across multiple targets.
• You’ll collaborate at the intersection of

  AI research, HPC, and language design

  .
• You’ll directly influence how large-scale systems run efficiently in production.
