As an AI Compiler Engineer on the Renesas HPC team, you will be responsible for driving compiler and code generation technologies that unlock the full compute potential of Renesas next-generation automotive System-on-Chip platforms, including advanced 3 nm silicon for software-defined vehicles (SDVs). Your work will directly impact how AI workloads - from perception and sensor fusion to in-vehicle assistants and advanced driver assistance - are translated into highly optimized, safe, and power-efficient execution on Renesas hardware.

This role bridges software compiler development, AI model lowering/optimization, and hardware-software co-design, enabling Renesas SoCs to deliver industry-competitive performance, efficiency, and functional safety required by multi-domain automotive applications..

Qualifications

What You'll Do

• Lead AI compiler architecture across model ingestion, graph optimization, lowering, code generation, and runtime integration
• Design and implement graph-level optimizations (operator fusion, quantization-aware rewrites, memory-aware scheduling, 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

What We're Looking For

• MS/PhD (or equivalent experience) in Computer Science, EE, or 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
• Experience with MLIR, LLVM, TVM-like systems, or proprietary compiler IRs
• Excellent C/C++ and Python skills
• Solid understanding of AI inference workloads (CNNs, transformers, perception or generative models)
• Strong communication skills are required, e.g. agile development experience in Scrum team (Product Owner or Scrum Master) 14 for Principal Engineer
• Strong communication skills are required, e.g. agile development experience in Scrum team (Scrum Master or member) 14 for Sr Staff Engineer

Additional Information

Nice to Have

• Experience with automotive or safety-critical systems
• Background in heterogeneous SoCs (CPU/GPU/DSP/NPU)
• Performance modeling or hardware-software co-design experience

Impact & Differentiators

Renesas' Gen5 R-Car automotive SoC lineup, including flagship 3 nm devices like the R-Car X5H, is among the first highly integrated multi-domain automotive SoCs built on advanced 3 nm process technology, designed to run ADAS, IVI, gateway, and next-gen SDV workloads on a centralized platform. These platforms deliver high AI performance (e.g., multi-hundreds of TOPS), scalable chiplet-based acceleration, and power efficiency tailored for electrified and autonomous vehicles while meeting stringent functional safety standards. An AI Compiler Engineer enables this hardware vision by ensuring that state-of-the-art AI models and computational kernels are efficiently mapped to the silicon fabric - directly enhancing performance, reducing latency and energy, and accelerating software adoption in automotive ecosystems where compute efficiency and safety are paramount.
