Senior Staff Engineer, Compiler (AI Compiler)

About the role

Renesas Electronics is hiring an AI Compiler Engineer on its HPC team in Kodaira. You will drive compiler and code generation technologies that unlock the compute potential of Renesas next-generation automotive System-on-Chip platforms, including advanced 3 nm silicon for software-defined vehicles. The role bridges compiler development, AI model lowering and optimization, and hardware-software co-design.

Key responsibilities

• Lead AI compiler architecture across model ingestion, graph optimization, lowering, code generation and runtime integration
• Design and implement graph-level optimizations such as operator fusion, quantization-aware rewrites, memory-aware scheduling and partitioning
• Drive performance optimization for target NPUs, including tiling, tensor layout and multi-core execution strategies
• Partner with SoC and AI accelerator architects to influence hardware features through compiler insights
• Own performance KPIs for real automotive AI workloads using simulators, profilers and silicon-correlated models
• Ensure compiler outputs meet automotive requirements (real-time behavior, determinism, quality expectations)
• Mentor senior engineers and set technical direction without people-management responsibilities

Required profile

• MS/PhD (or equivalent experience) in Computer Science, EE or a related field
• Deep experience building AI compilers, accelerator backends or graph optimization frameworks
• Strong expertise in graph optimization and performance optimization for NPUs or custom accelerators
• Solid understanding of AI inference workloads (CNNs, transformers, perception or generative models)
• Strong communication skills, e.g. agile development experience in a Scrum team (Scrum Master or member)

Required skills

• MLIR, LLVM, TVM-like systems or proprietary compiler IRs
• C/C++ and Python
• Nice to have: automotive or safety-critical systems experience, heterogeneous SoCs (CPU/GPU/DSP/NPU), performance modeling or hardware-software co-design

The company offers a hybrid work model with two days of remote work per week, and a career path across four product groups and departments.
