Job Overview
Are you passionate about the interaction between software and hardware and interested in applying your knowledge in a world-beating commercial processor group? Then this role may be just what you are looking for!
Arm's OS verification team is responsible for ensuring that ARM CPUs can boot operating systems and will be able to run real software. This includes early software bring-up on ARM CPUs with the goals of validating the hardware and of finding and investigating hardware and software bugs, which we can then investigate and share with hardware engineers to ensure their resolution.
We collaborate across our distributed team, as well as with colleagues in related software, hardware and architecture groups, allowing us to share optimum tools and ways of working.
If you enjoy low-level software development and are fascinated by the internal functioning of CPUs and operating systems, we would like to hear from you. This is an excellent opportunity to improve your software skills, while deepening your understanding of the internals of modern CPUs in an accomplished and diverse team!
Job Responsibilities
- Develop comprehensive OS-based validation test scenarios aligned with the test plan, architecture specifications, and targeted feature coverage.
- Bring up and configure OS environments and test payloads on target platforms, execute regression suites, and analyze test results to identify functional and stability issues.
- Debug and root-cause validation failures, including software/OS issues and hardware-related failures, and triage issues across HW, firmware, and software boundaries.
- Document defects with clear failure analysis, reproduction steps, logs, and supporting evidence, and collaborate with development teams through resolution.
- Track validation status, identify coverage or quality gaps, and communicate results, risks, and key findings to stakeholders.
