CPU Validation Software Engineer

Job overview:

Are you passionate about the interaction between software and hardware? Are you interested in applying your academic knowledge in a world-beating commercial processor group? Then this role may be just what you are looking for!

The verification software team in is responsible for developing a Random Instruction Stream generator which we use to stress Arm CPUs under development.

This enables us to search for hardware bugs, which we can then investigate and share with hardware engineers to ensure their resolution.

If you are an inquisitive engineer with an interest in low-level software development and the internal functioning of CPUs, we would like to hear from you. You will need an understanding of CPU architecture as well as an ability to design and implement in ‘C’. In this role, you will analyse complex CPU specifications, design new generator features to exercise them, and help triage and debug the issues found by the tool, running on FPGA.

Working in an exceptionally accomplished and diverse team, you will collaborate with engineers in a wide range of roles from CPU design and verification to processor architecture. Whether you prefer to focus on bare metal 'C' development, or on FPGA execution and bug hunting, this is a phenomenal opportunity to help verify the cutting edge CPUs of tomorrow!

Essential Skills & Experience

• You have software development experience with ‘C’ and some knowledge of low level assembler programming languages
• You understand CPU architecture and micro-architecture features (such as caches, MMU, SMP, coherency, CPU pipelines)

'Nice to Have' Skills & Experience

• You understand and can use the Arm instruction set architecture
• Exposure to a CPU verification environment at top level or system level
• Experience working in bare metal systems or low level operating systems for the purposes of functional verification
• Development experience or exposure to random instruction generators
• Experience with programming or using FPGAs
• Good university degree (or equivalent) in Computer Science, Electronic Engineering, or another appropriate field.
