Job description

We are hiring a CPU Performance Engineer focused on device-level performance analysis. This role sits at the intersection of real-world system behaviour and CPU microarchitecture, with the objective of understanding performance observed on devices and translating it into actionable insights for CPU design teams.

You will work on silicon platforms and real devices, analysing performance across complex and often non-deterministic environments. The role requires a solid foundation in CPU fundamentals, along with a strong interest in understanding how system-level behaviour maps to underlying microarchitecture.
