About the Position

We are looking for enthusiastic and motivated engineers who want to be part of a team building the compute platform for AI at scale!

Agentic AI is changing what CPU performance means in the cloud. As AI systems evolve from individual model calls towards complex, distributed workflows, performance increasingly depends on efficiently orchestrating models, data, tools, and services across the whole system.

You will join a diverse, dedicated, and inclusive group based in Arm's vibrant office at the heart of Manchester. Your work will help ensure the latest developments in AI take full advantage of Arm Neoverse platforms and pioneering cloud-server technologies like AGI-CPU, our CPU for next-generation AI data centers. Together with teams from across Arm, the open-source community, and our partners, you will be accelerating AI and helping build the future of computing on Arm.

We work on the full stack, from applications and frameworks to compilers, libraries, and assembly; we encourage everyone in the team to get involved in all parts. The team has a wide remit, but we are all aligned on a common goal. We trust and empower engineers with the autonomy to identify and solve problems without silos and with the support of their teammates.

Experience analyzing and optimizing CPU performance in heterogeneous CPU + accelerator systems
Familiarity with agentic AI frameworks and protocols
Understanding of CPU bottlenecks in agentic workloads
Understanding of databases, vector search, and retrieval systems
Familiarity with containers and cloud/server infrastructure
Familiarity with batching, scheduling, KV-cache management, collective communications, and distributed AI workloads
Understanding of parallel programming
Comfortable working across abstractions in the stack, from low-level optimization to high-level operators
Experience engaging with the open-source community and contributing to large open-source software projects
Experience optimizing software for AArch64/Arm servers, including SIMD technologies such as Neon™, SVE, and SME
