• Effective SME negotiation across disciplines, contracts, and programs.
• Modeling languages: VHDL‑AMS/MAST, State‑AMS; mixed‑signal and state‑aware models.
• Demonstrated expertise in high‑density or high‑efficiency power conversion, power sequencing, energy storage interfaces, or precision power control.
• Ability to analyze and troubleshoot designs at various maturity stages, including incomplete data sets, legacy architectures, and hardware already in build.
• Experience with environmental qualification, MIL‑STD design, and systems operating in shock, vibration, and thermal extremes.
• Understanding of EMI/EMC mitigation, grounding strategies, and system‑level power integrity.
• Experience in program leadership, technical direction, or multi‑disciplinary coordination.
• Mastery of harness effects, power quality, EMI/EMC, and Signal Integrity.
• Working knowledge of: MIL‑STD‑704, MIL‑STD‑1275, MIL‑STD‑461, MIL‑STD‑464, MIL‑STD‑1553, MIL‑STD‑1760, RS‑422/RS‑485, Ethernet/TSN.
• Familiarity with Model‑Based Engineering, requirements management, and digital engineering practices.

Responsibilities

• Chair technical reviews and set technical strategy and trade space across programs.
• Own cross‑subsystem interfaces and drive complex multi‑disciplinary issue resolution.
• Provide technical governance and adjudication across partner/supplier efforts; serve as technical authority.
• Architect high reliability power systems and precision analog subsystems for guidance, navigation, and control electronics.
• Lead power architecture trade studies, technology evaluations, and down‑selections aligned to performance, cost, producibility, and environmental constraints.
• 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.
• Coordinate with systems engineering, digital design, RF, modeling/simulation, GNC, thermal, and manufacturing disciplines to ensure robust and producible electrical power architectures.
• Communicate with Chief Engineers, PMs, Technical Fellows, Directors/VPs/Executives.
• Co‑optimization across electrical, thermal, structural, motor control, and mechanical impacts.
• Support technology roadmaps and contribute to long‑term capability development across the portfolio, including assessments of various platforms for missile integration.
• Influence over power architecture for next generation effectors and guidance systems.
• Technical leadership with visibility across RTX Missiles & Defense.
• Opportunities for advanced training, career development, and mentorship.
• Mentors senior talent; investigates, evaluates, troubleshoots, and adjudicates partner/supplier work.
• Present trade studies to stakeholders as needed.
• Rapidly learn and apply new technologies; prototypes cutting‑edge solutions.
• Focus on system trades, quantifiable decision‑making, and mandatory application of real‑world behaviors and military/aerospace specifications.
