Assess and address designs with varying design maturity: early concepts, partially complete hardware, and near production configurations. Identify gaps, risks, and improvement opportunities in immature or evolving designs, and mentor teams in closing those gaps. Perform detailed analysis of power system loads, margins, thermal impacts, transient behavior, and electromagnetic compatibility. Guide teams through component selection, derating, survivability requirements, and high‑reliability screening strategies. Participate in and lead engineering reviews, readiness events, risk reduction activities, cross‑disciplinary integration efforts, and failure review boards. Support hardware bring‑up, prototype evaluation, root‑cause analysis, and design refinement. Qualifications You Must Have Typically requires a Bachelors Degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 10 years of prior relevant experience to include any of the following: Power electronics, analog design, mixed‑signal design, or high‑reliability electronics development experience Enterprise / cross‑company multidisciplinary architecture development.
