The Advanced Effector Guidance Systems (AEGS) 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 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

· 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.

· Support technology roadmaps and contribute to long‑term capability development across the portfolio.

· Focus on system trades, quantifiable decision‑making, and mandatory application of real‑world behaviors and military/aerospace specifications.

Qualifications

• You Must Have Bachelor’s degree in Electrical Engineering or a related field; MS/PhD preferred.
• Minimum 8+ years of experience in power electronics, analog design, mixed‑signal design, or high‑reliability electronics development.
• Effective SME negotiation across disciplines.

Modeling languages

VHDL‑AMS/MAST, State‑AMS; mixed‑signal and state‑aware models.

Mandatory mastery of harness effects, power quality, EMI/EMC, and Signal Integrity.

Required 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.

Rapidly learns and applies new technologies; prototypes cutting‑edge solutions.

Negotiates with cross‑discipline SMEs and mentors P1–P3 engineers.

Collaboration and alignment across internal/external teams.

Presents trade studies to stakeholders as needed.

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.

Proficiency with SPICE simulation, modeling tools, and power/analog design best practices.

Must be able to obtain and maintain a U.S. Secret clearance.

Qualifications

• We Value 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.
• Understanding of EMI/EMC mitigation, grounding strategies, and system‑level power integrity.
• Experience in program leadership, technical direction, or multi‑disciplinary coordination.
• Familiarity with Model‑Based Engineering, requirements management, and digital engineering practices.

What We Offer

• 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.
• Competitive compensation and comprehensive benefits.
• Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world.
