Principal CPU Architect – CPU Design / Performance Modelling / Computer Architecture

We are currently partnered with a leading global semiconductor and compute technology organisation developing next-generation CPU architectures for flagship mobile and compute platforms. They are looking to hire a Principal CPU Microarchitect to drive innovation across advanced processor cores, focusing on workload-driven microarchitectural design and performance modelling.

Key responsibilities

• Define and evaluate advanced CPU microarchitectural features across fetch/decode, out-of-order execution, branch prediction, memory subsystems, cache hierarchy, and prefetching
• Develop and maintain cycle-accurate performance models using gem5 or equivalent simulation environments
• Drive workload analysis using performance counters, trace analysis, and profiling methodologies to identify bottlenecks and optimisation opportunities
• Evaluate performance improvements against industry-standard and mobile-focused benchmark workloads

Key requirements

• MSc, PhD, or equivalent industry experience in Computer Science, Electrical Engineering, or Computer Architecture
• Hands-on experience in CPU microarchitecture development for out-of-order processor cores
• Deep expertise in at least one major architecture domain such as branch prediction, prefetching, memory systems, cache coherence, or OoO execution
• Strong experience with cycle-accurate simulators such as gem5 or proprietary CPU modelling platforms
