Principal Analog Sustaining Engineer

Job Description

A key technical engineer tasked with investigating and resolving field failures and customer-reported issues on top-tier automotive PMIC products. Operating at the intersection of silicon behavior, system-level debugging, and customer interaction, lead root cause analysis from initial RMA intake to final resolution and knowledge sharing. Collaborate closely with customer applications teams, FA labs, and cross-functional engineering groups to deliver reliable, data-driven solutions for our customers.

• RMA Onboarding & Reproduction Setup:
  Review RMA documentation and debug history to understand failure symptoms; set up simulation and/or hardware debug environments to reproduce reported issues.
• Waveform & Silicon Analysis:
  Collect and analyze waveforms, run analog simulations, and review RTL/netlist to identify potential failure mechanisms and silicon behavior anomalies.
• Collaborative Debugging:
  Work closely with customer applications teams to align on debugging focus, share regular status and progress updates, and drive structured investigation plans.
• Advanced Failure Analysis:
  Initiate further analysis where required (e.g., FA lab), interpret results, and plan next actions to converge on root cause.
• Customer-Facing Technical Documentation:
  Create high-quality materials for customers including presentations, 8D reports, and any other relevant technical documents throughout the investigation lifecycle.
• Fix & Workaround Proposals:
  Propose silicon fixes or system-level workarounds, outline validation strategies, and review feasibility with customer applications teams and relevant internal departments.
• Root Cause Analysis Reports:
  Deliver comprehensive debug reports covering root cause analysis (RCA), fix proposals, and supporting data in a clear and structured format for both internal and external stakeholders.
• Technical Handoff & Closure:
  Conduct technical handoff meetings to ensure smooth knowledge transfer and formal case closure with all relevant teams.
• Cross-functional Collaboration:
  
  Engage with design, applications, test, and quality engineering teams to share learnings, drive design improvements, and contribute to sustaining quality initiatives.
• Ensure impactful dissemination of knowledge across Renesas design teams for lessons learned.
• Demonstrate risk astuteness, proactively implementing solutions with minimal input from the Manager
• Recognition for technical expertise in analog design across PMIC organization, demonstrated through proactive use of forums eg lunch and learns / skills training
• Demonstrate elements of Renesas values in all aspects of work
• Demonstrate continuous improvement of technical and non-technical skills, measured through manager review.

• Typically 12-15+ years' experience in IC design, with a strong focus on debug, failure analysis, or sustaining engineering
• Strong analytical mindset with the ability to drive structured, data-driven root cause investigations independently and collaboratively
• Demonstrated experience diagnosing complex silicon or system-level failures across mixed-signal PMIC environments
• Solid understanding of analog and digital circuit behavior, waveform analysis, and how design implementation manifests on silicon.
• Hands-on experience with industry-standard EDA and debug tools (e.g., Synopsys, Cadence, oscilloscopes, logic analyzers, simulation environments)
• Strong attention to detail and accuracy, with the ability to produce clear, concise technical reports and customer-facing documentation
• Excellent written and verbal cross-functional communication skills, including experience presenting technical findings to customers
• Structured problem-solving approach – open to new perspectives and able to build consensus across engineering and customer teams
• Experience with FA lab processes, failure analysis techniques (e.g. SEM, FIB, emission microscopy), and interpretation of physical failure analysis results
• Knowledge of Verilog, Verilog-AMS or scripting languages used to support debug automation or simulation
• Familiarity with 8D problem-solving methodology, structured debug reports, and customer quality processes

• BSEE…
