• Identify gaps, risks, and improvement opportunities and mentor teams to close those gaps.
• Perform detailed analysis of power system loads, margins, thermal impacts, transient behavior, and electromagnetic compatibility.
• Guide component selection, derating, survivability requirements, and high‑reliability screening.
• Participate in engineering reviews, readiness events, risk reduction activities, integration efforts, and failure review boards.
• Support hardware bring‑up, prototype evaluation, root‑cause analysis, and design refinement.
• Coordinate with systems engineering, digital design, RF, modeling/simulation, GNC, and manufacturing to ensure robust and producible power architectures.
• Communicate with Chief Engineers, Project Managers, Technical Fellows, Directors/VPs, and Executives.
• Co‑optimize across electrical, thermal, structural, motor control, and mechanical impacts.
• Support technology roadmaps and contribute to long‑term capability development.
• Influence power architecture for next‑generation effectors and guidance systems within RTX Missiles & Defense.
