Senior Staff Test Engineer - Reliability

We are seeking a Senior Staff Test Engineer - Reliability to own how we define, test, and prove the reliability of our complex electromechanical systems. You will set reliability targets and break top-level MTBF down into subsystem and component requirements. You will also determine the test quantity, duration, and confidence needed to demonstrate those targets, and focus testing where the risk is highest.

This is a technical leadership role. You will direct and advise a team of engineers on their test plans, method, and rigor, lead root-cause investigations across mechanical, electrical, and firmware domains, and run a closed-loop failure reporting process that feeds test, manufacturing, and field data back into design. You will work closely with design, manufacturing, and quality teams, and communicate reliability risks, test investment tradeoffs, and progress toward MTBF targets to engineering and program leadership.

• Reliability Strategy & Allocation: Define reliability targets and roadmap for the product, break top-level MTBF down into subsystem and component targets, and influence design through design reviews, derating guidance, and component and supplier qualification.
• Test Planning & Leadership: Lead a team of engineers on reliability testing, advising on method and rigor, and determine the sample size, test duration, and confidence level needed to demonstrate top-level MTBF, targeting testing at the highest-risk components and subsystems (life, stress, HALT/HASS, thermal, environmental).
• Failure Analysis & Root Cause: Lead root-cause investigations of failures from test, manufacturing, and the field, coach engineers through the analysis, and run a closed-loop failure reporting system (FRACAS) that feeds field and returns data back into design.
• Reliability Modeling & Data: Guide the team in building life and failure-rate models (Weibull, FMEA inputs, fault trees, reliability block diagrams), roll component test results up to system-level MTBF estimates with confidence bounds, and track reliability growth over time against the MTBF target.
• Technical Leadership & Mentorship: Mentor and grow engineers, partner with design, manufacturing, and quality teams, and present reliability risks, test investment tradeoffs, and progress toward MTBF targets to leadership.
