At Raytheon (RTX), we draw on more than 100years of engineering expertise to help our nation and allies defend freedoms and deter aggression. Our Advanced Effector Guidance Systems (AEGS) Department provides Electrical Systems Engineering for electronic systems solutions across the Raytheon portfolio, focusing on architecture, requirements, integration, and test.

The Advanced Effectors Guidance Systems Department seeks a Principal Electrical Subsystem Architect to lead architecture development for next‑generation missile guidance, control, and sensing electronics. The architect will define and drive technical direction for high‑reliability power conditioning, energy delivery, and precision analog subsystems in extreme missile environments.

• 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 at varying maturity stages—from early concepts through detailed design and transition to production.
• Identify gaps, risks, and improvement opportunities in immature or evolving designs, mentoring teams to close 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.
• Rapidly learn and apply new technologies; prototype cutting‑edge solutions.
• Support technology roadmaps and contribute to long‑term capability development across the portfolio.
• Negotiate with cross‑discipline SMEs and mentor engineers.
• Collaborate and align across internal/external teams, presenting trade studies to stakeholders as needed.

• Typically requires a Bachelor’s Degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of relevant experience.
• Minimum 8+ years of experience in power electronics, analog design, mixed‑signal design, or high‑reliability electronics development.
• Experience with modeling languages: VHDL‑AMS/MAST, State‑AMS; mixed‑signal and state‑aware models.
• Experience with harness effects, power quality, EMI/EMC, and signal integrity.
• Experience with environmental qualification, MIL‑STD design, and systems operating in shock, vibration, and thermal extremes.
• Advanced degree in Electrical Engineering or a related field; MS/PhD preferred.
• Experience with missile systems, guidance electronics, harsh‑environment power systems, or seeker/power integration.
• Hands‑on experience with lab bring‑up, prototype testing, instrumentation, and failure analysis.
• Proficiency with SPICE simulation, modeling tools, and power/analog design best practices.
• Understanding of EMI/EMC mitigation, grounding strategies, and system‑level power integrity.
• Experience in program leadership, technical direction, or multi‑disciplinary coordination.
• Experience working with 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.
• Demonstrated expertise in high‑density or high‑efficiency power conversion, power…
