Senior Principal Electrical Subsystem Architect

Senior Principal Electrical Subsystem Architect

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today's mission and stay ahead of tomorrow's threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The Advanced Effectors Guidance Systems Department within Raytheon Hardware Engineering provides Electrical Systems Engineering to develop Electronic Systems solutions for products across the Raytheon portfolio. Our core electrical engineering responsibilities include architecture, requirements, integration, and test. Our core electrical engineering technologies include RF/RADAR, Navigation/IMU/GPS, Data Link/Communication, Digital, and Power. We partner with several Electrical Product Team departments that provide the detailed design of our electrical products as well as systems teams.

The Advanced Effectors Guidance Systems department is seeking a Senior Principal Electrical Subsystem Architect to lead architecture development for next-generation missile guidance, control, and sensing electronics. This position defines and drives the technical direction for high reliability power conditioning, energy delivery, and precision analog subsystems that operate in extreme missile environments. The architect will evaluate, mature, and guide designs across a wide range of development stages-from early conceptual modeling through detailed design, integration, and transition to production.

What You Will Do

• 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, legacy designs requiring modernization, 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, 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.
• 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.

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
• Minimum of 10 years' experience in power electronics, analog design, mixed-signal design, or high-reliability electronics development.
• Enterprise / cross-company multidisciplinary architecture development.
• Partner / SME adjudication and technical governance experience.
• Experience with VHDL - SMS / MAST plus mixed-domain governance and correlation (electrical, thermal, mechanical).
• Experiencing building platform roadmaps; evaluating and integrating cutting-edge technologies.

What We Offer

Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. At RTX we value: Trust, Respect, Accountability, Collaboration, and Innovation.
