CPU Research Engineer

CPU Research Engineer (Contractor)

A leading semiconductor organisation is seeking a CPU Research Engineer to work on next-generation mobile processor microarchitecture, focusing on performance-per-watt improvements and advanced out-of-order execution design.

Successful candidates will research, model, and optimise CPU architectures, contributing to the design of high-efficiency mobile CPUs through simulation, profiling, and microarchitectural innovation. This is a highly technical role combining academic research depth with practical CPU design impact.

Ideal candidates will have knowledge of:

• Computer architecture (superscalar, out-of-order execution)

• CPU microarchitecture (fetch, decode, branch prediction, renaming, issue queues, ROB)

• Performance and power optimisation (IPC, perf-per-watt analysis)

• Cycle-accurate simulation (e.g. gem5, Sniper, ChampSim)

• Hardware performance counters and workload profiling

• Instruction scheduling, register allocation, and code generation

• C, C++, Python, and assembly (ARM64 or RISC-V)

• Compiler fundamentals (LLVM, GCC, PGO, backend design)

• Speculative execution and branch prediction techniques

• Microarchitectural modelling and simulation frameworks

• OS internals (scheduler, memory management basics)

• Academic research integration into CPU design
