Compiler Engineer — MLIR

Location: Mountain View, CA

Department: Software

About the role

Own MLIR dialect design and lowering passes for our AI accelerator — defining the high-level tensor IR, async / streaming semantics, and sharded-tensor types that bridge ML frameworks to silicon. Work with chip-design and software teams driving DensityAI's AI accelerator program from first silicon through scale-out.

What you'll do

• Own MLIR dialect design and lowering passes for our AI accelerator — defining the high-level tensor IR, async / streaming semantics, and sharded-tensor types that bridge ML frameworks to silicon
• Use and develop AI-assisted tool flows to accelerate compiler development

What we're looking for

• Exceptional abilities in MLIR dialect design, lowering pass authoring, and rewrite patterns
• 5+ years compiler engineering experience, with hands-on MLIR contributions or equivalent IR-design experience
• Deep understanding of tensor compilation, distributed / sharded execution, and async / streaming dataflow models
• Strong C++ fluency and experience integrating with ML frameworks (PyTorch, JAX, ONNX, TensorFlow, or equivalent)
• (Optional) LLVM backend experience, GPU compiler experience (Triton, IREE, XLA, or equivalent), or open-source MLIR / LLVM contributions

Compensation

Final offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO.
