About the role
Job Overview
We are seeking a highly motivated and creative person to join our Cambridge-based toolchain performance team.
This is an excellent opportunity for a Software Engineer who specialises in Developer Infrastructure and Platform Engineering and has keen interest in Dev Ops, software quality and performance testing, who wants to influence the future of Arm IP and the Arm eco-system.
Our team works on a diverse range of compilers and toolchains. From popular open-source projects like GNU and LLVM to closed sourced Arm compilers. Our goal is to tackle software performance challenges whenever they occur. We monitor the performance of vital toolchain and system components across a large number of hardware and software platforms. Your work will allow us to manage this unique complexity and provide the toolchain engineering teams with high-quality, reliable tracking of the state of the world of software on Arm IP.
This involves writing custom code to extend existing software or to connect systems together that are not usually deployed together. You will also manage a spread of hardware benchmarking platforms: mobile phones, developer boards, big servers as well as FPGAs and simulators for brand-new CPU designs.
Our existing infrastructure has been developed over time to meet our team's specific requirements, and we will be happy to ramp you up on its structure and components until you are comfortable owning its further evolution.
We are one of a number of compiler engineering teams in Arm, and we have plenty of passionate and friendly DevOps engineers specialising in toolchain testing who will be delighted to help you.
Location
This position is situated in our Cambridge head office which hosts diverse teams from across Arm including development tools, compilers, debuggers, technical communications, DevOps infrastructure provision and open-source software development.
