Job Summary

We are seeking a Principal GPU/NPU Software Architect to play a pivotal role in designing and implementing the core software that enables our revolutionary hardware. This is not a maintenance role; it is a ground-zero opportunity to architect the low-level software stack for a heterogeneous computing platform where the GPU, NPU (Neural Processing Unit) and other modules are designed for deep, synergistic cooperation. Your work will be critical to unlocking the full potential of neural rendering, machine learning and other technologies where traditional rasterization pipelines seamlessly fuse with real-time neural networks to generate imagery.
You will be the bridge between our software and hardware architecture team and our research teams in neural graphics, defining the APIs and abstractions that will empower developers to create the previously impossible.

Key Responsibilities

• Architect the Co-Processing Driver Stack: Design and implement the low-level driver, compiler, and runtime for a tightly integrated GPU/NPU architecture. Enable efficient memory sharing, low-latency synchronization, and collaborative execution of graphics and neural workloads.
• Pioneer Neural Rendering Infrastructure: Develop the core driver and API extensions to support emerging neural rendering techniques, such as neural radiance fields (NeRFs), neural texture compression, AI-based denoising, and AI-powered upscaling within the rendering pipeline.
• Drive Hardware-Software Co-Design: Work directly with hardware engineers to influence the design of future GPU/NPU architectures, ensuring the ISA, memory hierarchy, and interconnects are optimized for next-generation graphics and AI workloads.
• Performance Analysis & Optimization: Attain unparalleled performance by deep-diving into the hardware pipeline. Identify and eliminate bottlenecks in the interaction between graphics shaders and neural network execution.
• Define the Programming Model: Create and document the programming models, APIs, and developer tools that will allow internal and external graphics engineers to leverage the combined power of the GPU and NPU effectively.

This job description is only an outline of the tasks, responsibilities and outcomes required of the role. The jobholder will carry out any other duties as may be reasonably required by his/her line manager. The job description and personal specification may be reviewed on an ongoing basis in accordance with the changing needs of Huawei Research and Development UK Limited.

Required

• Master's or PhD in Computer Science, Electrical Engineering, or a related field, or equivalent practical experience.
• 10+ years of proven, deep experience in developing low-level GPU drivers, runtime, or compiler technology for a major mobile GPU architecture.
• Expert-level knowledge of modern graphics APIs (Vulkan, DirectX 12) and their compute shader pipelines.
• Fluency in C/C++ and a strong understanding of computer architecture.
• Must have a proven track record in co-processor design (e.g., GPU/CPU, GPU/DPU) or developing drivers for heterogeneous systems.

Desired

• Direct experience with NPU/AI accelerator architecture or driver development. You understand the nuances of mapping neural networks efficiently onto tensor cores.
• Hands-on experience implementing or optimizing neural rendering technologies (e.g., NeRF, DLSS/FSR, neural graphics primitives).
• Deep understanding of the ML compiler stack (e.g., MLIR, LLVM).
• Experience with hardware virtualization (SR-IOV) for GPU/NPU resources.
