You will work hands-on with bring-up systems, validation boards, and customer platforms, closely partnering with Customer Engineering, architecture, RTL, firmware, and post-silicon debug teams to drive root cause and mitigation.
Key Responsibilities
- Develop and run C and assembly tests directly on silicon (Bare Metal/OS based) to provoke and detect silent corruption in:
- CPU pipelines, load/store, atomics, coherency, and cache interactions
- Build robust correctness oracles (redundant execution, invariants, checksums) to catch subtle wrong-answer failures.
- Analyze and root-cause customer-reported issues with symptoms such as data corruption, miscompares, or non-deterministic failures without explicit machine checks.
- Work closely with Customer Engineering to:
- Reproduce issues in lab or customer-like environments
- Triage logs, dumps, and limited telemetry
- Provide clear technical root-cause hypotheses and mitigation guidance
- Use post-silicon debug techniques:
- Performance counters, trace, JTAG, register/state dumps, targeted instrumentation
- Reduce issues to minimal repros (often assembly-only) to enable efficient handoff to RTL and architecture teams.
- Integrate high-signal SDC tests into ongoing datacenter stress and regression flows.
Required Qualifications for this Role:
- Strong C, Python, ARM assembly programming skills.
- Solid understanding of computer architecture concepts, OOO execution, ARM ISA
- Experience debugging silicon failures.
- Ability to reason across hardware, firmware, OS, and workload behavior.
- Strong analytical and communication skills for customer-impacting issues.
Preferred Qualifications
- Experience working directly with customers or field teams on CPU issues.
- Familiarity with RAS and reliability features (detection, containment, escalation).
- Experience with silicon bring-up, validation boards, or datacenter/enterprise CPU deployments.
Minimum Qualifications:
Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field and 4 years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience.
