CPU Post-Silicon RAS Engineer

Company:
Qualcomm Technologies, Inc.

Job Area:
Engineering Group, Engineering Group > CPU Engineering

General Summary:

We are seeking a post-silicon CPU RAS engineer focused on Silent Data Corruption (SDC) / Silent Data Errors (SDE) on ARM ISA-based CPUs running on silicon platforms. This role centers on reproducing, detecting, and root-causing failures escaping, often observed in customer or field environments. 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.
OR
Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field and 3+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience.
OR
PhD in Electrical Engineering, Computer Engineering, Computer Science, or related field and 2+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience.
