Senior Performance Modelling Engineer (CPU group)

In this role, you will contribute to designing power-efficient Arm CPUs for future workloads. You’ll work with CPU engineering teams to evaluate and enhance performance features across micro-architectures, using innovative analysis techniques to uncover opportunities for improvement. You’ll operate across a global, collaborative team and mentor junior engineers, driving best-in-class performance methodologies. This is a chance to influence how processors balance power, performance, and area at scale, shaping the next generation of devices.

• Analyze 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 uses emulators, simulators, and FPGAs to evaluate performance and power
• Provide actionable insights to customers, architects, and marketing teams on IP performance across scenarios

• 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 scripting skills (Shell, Python, or Perl)

• Collaboration across cross-functional teams
• Mentoring of junior engineers
• Analytical thinking and problem solving
• CPU micro-architecture fundamentals
• Low-level programming (embedded C/assembly)
• Linux scripting (Shell, Python, Perl)
