Staff Engineer in Software Performance opportunity at Arm's Global Headquarters in Cambridge (a mixture of remote and office based)


Arm technology is pervasive around the world. The Performance Solutions team within the Development Solutions Group ensures that foundational, performance-critical software like compilers and runtime libraries make the best use of our hugely diverse IP portfolio.

Do you like to tackle performance problems, wherever they occur in the stack? In our team you can analyse CPU traces, design innovative code generation techniques, contribute your work directly to popular open source projects like LLVM, and work with engineers in the vast Arm ecosystem on solutions that ship billions of chips a year.

The insights produced in our team are used to improve a large diversity of Arm IP and surrounding software, from CPU architecture and microarchitecture, to performance libraries, to end-user guidance.

We use modern infrastructure, tailored to our needs, to manage the complexity of our work, including systematic performance tracking across microcontrollers and big servers, automatic build and regression test systems and more!

You have an analytical mentality, the desire to handle big picture problems, the excellent software engineering skills to make your solutions a reality, and the collaborative approach to get your work accepted in open source communities?  We want to talk to you!
