CPU Performance Modelling Engineer

Company: A leading global innovator in information and communications technology, specializing in the design and development of advanced CPU architectures. Location: Cambridge, UK Job Summary: Join our dynamic CPU Architecture team at our UK Research Centre and play a pivotal role in shaping the future of next-generation CPU innovations. As a Performance Modelling Engineer, you will utilize advanced modelling, simulation, and workload characterization techniques to evaluate hardware design choices, quantify trade-offs, and provide data-driven insights that drive our architectural roadmap. Key Responsibilities: Design, implement, and refine performance models that accurately predict CPU microarchitecture behaviour. Maintain and enhance in-house toolchains for cycle-accurate, trace-driven, and statistical simulations. Assess the feasibility and cost-benefit trade-offs of new CPU features through in-depth performance and power analyses. Develop new methodologies, automate workflows, and create intuitive visualizations to identify bottlenecks and guide optimizations. Collaborate with architects, software engineers, and a global community of performance modelling experts on design reviews and best practices. Continuously improve modelling strategies to inform next-generation CPU innovations. Required Qualifications: Bachelor’s (BS) or Master’s (MS) degree in Computer Science, Electrical Engineering, or related fields, with coursework or relevant experience in Computer Architecture. Proven experience in performance modeling and analysis of CPU microarchitecture. Familiarity with cycle-accurate, cycle-approximate or functional simulators, microarchitecture pipelines, and common performance metrics. Strong proficiency in C/C++ for large-scale software development, with working knowledge of Python for scripting and data analysis. Excellent interpersonal skills and a track record of collaborative work in multi-disciplinary teams. Ability to communicate technical concepts clearly to both technical and non-technical audiences. Desired Qualifications: Experience with power models and cache system models. Strong software development experience, including design specification, coding, testing, and debugging. Experience with, or understanding of, Arm architectures (e.g., Armv8-A, Armv9-A). Exposure to microarchitecture-level performance counters, or hardware-software co-optimization. Experience with RTL and SystemC simulators. Knowledge of System Architecture/Software. What We Offer: Innovative Environment: Work on cutting-edge research that influences global CPU designs. Global Collaboration: Collaborate with a diverse, international team of experts. Professional Growth: Access training, mentorship, and development opportunities. Impactful Work: Contribute to CPU solutions used in millions of devices worldwide.
