Front End Compiler

Design, develop, and maintain the front end of our heterogeneous AI compiler, including parsing, validation, and IR lowering stages

Build and extend ingestion pipelines for ML frameworks and representations including PyTorch, StableHLO, ONNX, and MLIR-based dialects

Define and evolve the interface between external model representations and our internal compiler IR

Ensure correctness and completeness of operator coverage across supported frameworks and hardware targets

Collaborate with graph optimization and code generation teams to ensure clean, well-structured IR that enables downstream transformations

Use performance and correctness data to identify gaps in coverage and drive improvements

Contribute to documentation and tooling that helps ML engineers understand and debug the ingestion process

Build the entry point for an AI compiler that targets every major hardware platform

Work at the boundary of ML frameworks and compiler infrastructure — a rare and high-leverage intersection

Tackle deep correctness and coverage problems that directly impact what models can run and where
