About the role

View original

CAPA Leadership & Escalation Ownership : Serve as the single point of contact for all EE Corrective and Preventive Action (CAPA) issues. Take charge of investigating fleet issues, establishing immediate containment paths, and driving permanent resolutions

Hands-on Lab Diagnostic Validation : Conduct intensive hands-on electrical lab bench testing to reproduce fleet and manufacturing anomalies. Utilize standard laboratory diagnostic equipment (oscilloscopes, digital multimeters, power supplies, logic analyzers, and electronic loads) to validate containment strategies and prove out root-cause theories

Root Cause & Failure Analysis : Lead end-to-end problem resolution spanning from initial telemetry data parsing to deep-dive root cause analysis. Partner closely with our internal Failure Analysis (FA) experts to diagnose complex electronics and hardware system failures

Design Ownership for Reliability : Directly drive the continuous improvement of our deployed hardware ecosystem. You will have the technical authority to own and execute the engineering change lifecycle—from designing and releasing targeted PCBA revisions to identifying, testing, and qualifying strategic off-the-shelf (OTS) components—to permanently eliminate failure modes and improve system performance

Cross-Functional Tiger Team Representative : Act as the authoritative EE voice on the cross-functional CAPA Tiger Team. Interface daily with Core Reliability, Mechanical, Software, and Manufacturing teams to ensure a unified approach to system-level reliability

Technical Triage & Strategy : Function as the primary gatekeeper for incoming electrical engineering challenges. For specialized issues, triage, prioritize, and collaboratively map out resolution strategies with design specialists across the EE department

Metrics & Infrastructure Management : Own and optimize the EE Atlassian/Jira Problem dashboard. Systematically track, analyze, and report on key performance indicators (e.g., Mean-Time-Between-Swaps/MTBSwap) to demonstrably reduce field failure rates and eBox replacements

Technical Knowledge Capture & Standards : Author comprehensive failure analysis reports, root-cause whitepapers, and standardized electrical triage workflows. You will turn deep-dive technical findings into institutional knowledge, creating the foundational documentation required to scale this sub-team and uplevel the broader engineering organization
