Principal Modelling Engineer – Design Space Exploration – Part Time – Cambridge


Job Overview:

The Central Technology (CT) Group at Arm is responsible for examining and defining the future of Arm solutions to the next generation of challenges.

You will join the design space exploration (DSE) team to create approximated early IP performance models that are then used for DSE studies. The DSE team works closely with IP teams, system architects, and product managers to gather technology trends and conduct exploratory studies. This role will allow you to work on topics like power/thermal modelling, thermal control, job scheduling, caching, and modelling of processing elements, interconnects, and memories. You will also use the DSE performance models to explore PPA of multiple system architecture candidates for key use-cases (e.g., gaming, AI camera, video streaming) to identify the most promising future system architectures. You will contribute to an exciting, engineering-focused environment in a field that is at the forefront of new technology in the industry.
