About the role

Own LLVM backend development for our custom accelerator ISA — instruction selection, register allocation, scheduling, and linker support across scalar, vector, and floating-point pipelines. Work with chip-design and software teams driving DensityAI's AI accelerator program from first silicon through scale-out.

What they're looking for

  • Exceptional abilities in LLVM backend internals (TableGen, instruction selection, scheduling, register allocation)
  • 5+ years of compiler engineering experience, with hands-on LLVM target development
  • Strong understanding of computer architecture, ISA design, and compiler-hardware co-design
  • Ability to debug correctness and performance regressions across the full compilation flow
  • (Optional) Custom-ISA bring-up, MLIR experience, GPU / accelerator backends, or linker / loader work
