Principal Analog Sustaining Engineer

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.

** Principal Accountabilities*
* + 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.

Qualifications

+ 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…
