Senior Principal NPU Architect

About the Role

We are seeking a
Senior Principal NPU Architect
to define the architecture of next-generation AI accelerators for high-performance and power-efficient autonomous driving NPU. You will drive architecture decisions across compute, memory hierarchy, interconnect, dataflow, and software co-design, enabling competitive performance for modern AI workloads such as CNNs, Transformers, multimodal models, and LLM inference.

Key Responsibilities

  • Define NPU architecture and key design directions for compute, memory, interconnect, and execution model.
  • Analyze AI workloads and translate them into architecture requirements and trade-offs.
  • Drive architecture modeling, bottleneck analysis, and architecture exploration.
  • Partner with compiler, runtime, and algorithm teams on hardware/software co-design.
  • Guide architectural optimization for performance, power, area, and scalability.
  • Work with RTL, verification, and software teams to ensure successful implementation.

Qualifications

  • MS or PhD in EE, CE, CS, or related field.
  • 8+ years of experience in NPU, GPU, CPU, ASIC, or computer architecture.
  • Strong understanding of AI/ML workloads, memory systems, parallel processing, and performance optimization.
  • Proven experience in architecture definition, modeling, and hardware/software co-design.
  • Familiarity with low-precision computing and quantization, such as INT8, FP16, BF16, or FP8.
  • Strong technical leadership and cross-functional communication skills.

Preferred Qualifications

  • Experience with AI accelerators for edge AI, datacenter AI, or autonomous driving.
  • Familiarity with AI compiler/runtime stacks and workload mapping.
  • Track record of architectural innovation, silicon delivery, or published technical contributions.
