ML Systems & Compiler Research Engineer

Huawei Technologies Research & Development (UK) Ltd; Cambridge; On-site; GBP 90,000 - 140,000; Full time

Job summary

Huawei Research and Development UK Limited in Cambridge is seeking an engineer to work on CPU research where AI meets low-level systems. You will design and implement compiler passes, JIT paths, and runtimes on ARM64 platforms, collaborating with CPU architects and kernel engineers.

The role requires strong C++ and Python, plus hands-on experience in at least two areas such as compiler infrastructure, language runtimes, or RL-based training. A non-trivial end-to-end project is highly valued.

Qualifications

• BSc or MSc in Computer Science, Electrical Engineering or a related field, or equivalent practical experience.
• Strong C++ and Python.
• Hands-on experience in at least two of: compiler infrastructure (LLVM, MLIR, or a custom compiler); language runtimes (JITs, interpreters, etc.); training or post-training models (reinforcement learning).

Responsibilities

• Design and train RL and LLM-based agents that discover and verify performance optimisations in kernels, language runtimes and compiler output.
• Build the infrastructure around those agents: reward design, sandboxed execution environments, benchmark harnesses, and verification that catches reward hacking.
• Write and optimise performance-critical code, such as compiler passes, interpreter and JIT hot paths, and runtime data structures, and measure it on real hardware.
• Turn research papers into working prototypes quickly, and turn strong prototypes into patents and publications.
• Work with CPU architects and kernel and compiler engineers to turn ML-driven insights into hardware-software co-design proposals.
