Front End Compiler

Lemurian Labs is reimagining the foundations of computing to make AI accessible to everyone. They are seeking a Front End Compiler Engineer to own the ingestion layer of their high-performance, portable AI compiler, building systems that parse and validate representations from various ML frameworks.

Responsibilities:

• 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
