The Future of AI is Built on Arm. Are you fascinated by how cutting‑edge CPUs are engineered to power every corner of the technology world? Do you want to contribute to the momentum that’s transforming how people work, play, and connect? At Arm, your work will impact billions of lives. If you’re passionate about building technology that powers everything from smartphones to supercomputers, we’d love to meet you. This is an excellent opportunity to grow your skills in CPU performance engineering, be a part of an established CPU performance optimisation team and contribute to world‑leading processor designs. As a CPU Performance Benchmarking Engineer, you’ll be at the heart of designing Arm’s power‑efficient CPUs for the next generation of workloads. You’ll define and deliver critical performance and power metrics, apply innovative analysis techniques, and uncover opportunities to push processor and cache performance even further.

Job Overview

You’ll join forces with CPU engineering teams across the UK to evaluate and enhance the performance features of world‑class micro‑architectures. Working with workloads that mirror what future CPUs will run, you’ll continuously evolve our methodologies to ensure they remain best‑in‑class. If you’re excited by the idea of peering under the hood of CPUs, understanding their inner workings, and pushing their limits, this role is for you. It’s an exceptional opportunity to be part of a world‑leading CPU performance optimisation team.

Responsibilities

• Analyse and report CPU/IP performance across the full development cycle.
• Collaborate with designers and performance engineers to improve power, performance, and area (PPA) of IPs.
• Develop and enhance infrastructure that employs emulators, simulators, and FPGAs to evaluate performance and power.
• Provide actionable insights to customers, architects, and marketing teams on how IPs perform across different scenarios and use cases.

Required Skills and Experience

• Strong grasp of CPU micro‑architecture concepts (pipelines, caches, predictors, MMUs).
• Hands‑on experience with low‑level embedded C or assembly for coding, testing, optimisation, and debugging.
• Proficiency in Linux environments with strong scripting skills (Shell, Python, or Perl).

Nice To Have Skills and Experience

• Solid background in CPU performance analysis using industry benchmarks.
• Familiarity with HDL languages (Verilog/VHDL) and RTL simulator/emulator environments.
• Exposure to hardware design and/or CPU performance modelling.
• Understanding of the Arm instruction set architecture and assembly language.
• Familiarity with compilers and code generation techniques.
• Broader knowledge of system architecture.
• A strong academic background with a degree in Computer Science, Electronic Engineering, or a related field.
