Front-End Compiler Engineer

Job overview

The Front-End Compiler Engineer role is onsite in Santa Clara, CA. Compensation is not specified. The role supports Lemurian Labs’ effort to make AI accessible through a hardware-agnostic software platform. The engineer builds the ingestion layer of the AI compiler, translating external machine-learning framework representations into the company’s internal compiler intermediate representation. This work establishes correct, comprehensive inputs for downstream graph optimization and code generation, helping models run across supported hardware targets.

What you'll do

• Design, develop, and maintain compiler parsing, validation, and intermediate-representation lowering stages
• build ingestion pipelines for PyTorch, StableHLO, ONNX, and MLIR-based dialects
• define interfaces between external model representations and internal compiler IR
• improve operator correctness and coverage across frameworks and hardware targets
• collaborate with graph optimization and code generation teams
• use performance and correctness data to identify gaps
• contribute documentation and debugging tools for machine-learning engineers.
