We are seeking an accomplished CPU Architect to help define the next generation of high-performance processors.
This is a senior individual-contributor role with substantial technical influence and long-term strategic impact. You will investigate architectural concepts several years ahead of production, shaping innovations across instruction-set architecture, microarchitecture, workload analysis and hardware/software co-design.
Your work will focus on emerging computational demands, including generative AI, large language models, graph analytics and confidential computing.
What You’ll Do
- Lead architectural exploration and pathfinding for future CPU designs and enabling technologies.
- Develop microarchitectural concepts spanning instruction fetch and decode, execution pipelines, out-of-order scheduling and multi-level memory systems.
- Investigate and define ISA enhancements, including vector and matrix extensions and specialised compute instructions.
- Analyse emerging workloads, identify software bottlenecks and translate findings into architectural requirements.
- Collaborate with compiler, operating-system and application specialists on hardware/software co-design.
- Guide the creation of cycle-accurate CPU simulation models in C++, C and Python.
- Assess architectural proposals against performance, power and area targets.
- Provide senior technical leadership and contribute to long-range technology roadmaps.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You’ll Bring
- At least 10 years of relevant industry experience, including substantial work in high-performance CPU architecture.
- Expert knowledge of out-of-order execution, speculative execution, branch prediction, register renaming, cache hierarchies and coherency protocols.
- A strong understanding of ISA design, exception models, memory-consistency models and virtualisation.
- Practical experience in workload profiling using performance counters, simulation traces and related techniques.
- Familiarity with performance-analysis environments such as Perf, VTune or SimPoints.
- Strong experience developing cycle-accurate architectural simulators using C, C++ and Python.
- A master’s degree or PhD in Computer Engineering, Computer Science, Electrical Engineering or a related discipline.

Additional Experience That Would Be Valuable
- Involvement in multiple high-performance CPU programmes through silicon tape-out.
- Architecture experience across x86, Arm and/or RISC-V.
- Contributions to LLVM, GCC, architectural frameworks or open ISA communities.
- Knowledge of chiplets, 3D integration and advanced semiconductor packaging.
Why Consider This Role?
This is an opportunity to influence processor technology years before commercial deployment and to work on some of computing’s most demanding and rapidly evolving workloads.
You will have the scope to shape future CPU architectures, collaborate across hardware and software disciplines, and contribute to long-term technology decisions with significant industry impact.
