GPU Chief Architect / XPU Lab Director

Job Summary

•We are seeking a highly experienced GPU architect to lead the definition and execution of next-generation mobile GPU architecture in our Kirin SOC, while driving architectural convergence between GPU and NPU toward a coherent xPU sub-system design.

•This role requires deep expertise in GPU microarchitecture, strong system-level architectural capability, including both hardware and software, and a thorough understanding in graphics and AI common workload. A proven track record of delivering related sub-system IP or complex SoC silicon is highly desirable.

•The successful candidate will lead the effort in shaping a converged xPU architecture native for future AI compute, optimised for performance, power efficiency, and silicon area in the next generation mobile compute platforms.

Key Responsibilities:

• xPU Converged Architecture Design

• Based on 1st order principle, analyse and characterise future mobile graphics and AI workload, redefine an xPU (GPU & NPU) converged architecture, including hardware and software, from the ground up that is optimal for future applications.
• Ensure compatibility or easy transition from the old architecture.
• Define unified or partially unified execution resources (vector, scalar, tensor units)
• Develop shared scheduling and workload dispatch mechanisms for graphics and AI
• Design resource sharing and isolation strategies under mixed workloads
• Evaluate architectural trade-offs between dedicated and converged compute blocks

• Mobile GPU Architecture Leadership

• Ensure the timely delivery of next-generation mobile GPU architecture and long-term roadmap
• Lead evolution of shader cores, execution pipelines, and cache hierarchy
• Drive performance, power efficiency (Perf/W), and area efficiency (Perf/mm²)
• Provide architectural leadership from concept phase through tape-out

• Memory & Interconnect Architecture

• Define a memory hierarchy strategy for converged GPU/NPU workloads
• The architect shared cache structures and bandwidth arbitration policies
• Optimise on-chip interconnect for heterogeneous compute traffic
• Reduce data movement overhead across compute domains

• System-Level Architecture Collaboration

• Collaborate with CPU, AI software, runtime, and system architecture teams
• Participate in SoC-level power, thermal, and floorplanning trade-offs
• Align hardware architecture with graphics APIs and AI frameworks
• Support performance modelling, workload characterisation, and silicon bring-up
