Opportunities for permanent roles in a range of business sectors

Performance Modelling Architect

Do you have a deep understanding of modern system architecture and excellent programming skills? Then this job is your opportunity to achieve the biggest possible impact in the field. You will join a team tasked with guiding the direction our future technology and that of hundreds of Arm's partners.

Modern chip designs incorporate a wide range of Arm components to construct a full system, each part having an impact on the overall system performance. Whether it is a car engine monitor, a VR headset or a network server, it is critical that all Arm components perform well when combined into systems. Central Technologies Group (CTG) at Arm drives the development of IP across the company. Even before a new product is conceived, system models are constructed to examine the advantages of potential new architectural features. Modelling engineers define and examine new designs within a full system context prior to commitment to an RTL product. Identifying issues early is key to deliver world-class IP used in billions of products. As a modelling engineer, you will work with architects who wish to examine future ideas, with design teams aiding them to identify performance issues and customers to capture target system specifications to ensure our designs will work well within them.
