Job description

Date Posted: 2026-05-11 • Country: United States of America • Location: Tucson, AZ – 1151 E Hermans Rd – BLDG M02 • Position: Principal Electrical Subsystem Architect (Onsite)

The Advanced Effector Guidance Systems (AEGS) Department within Raytheon Hardware Engineering is seeking a Principal Electrical Subsystem Architect to lead architecture development for next‑generation missile guidance, control, and sensing electronics. The role defines and drives the technical direction for high reliability power conditioning, energy delivery, and precision analog subsystems that operate in extreme missile environments.

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 maturity, covering early concepts, partially complete hardware, legacy 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.
• 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 and external teams.
• Effectively negotiate across disciplines.
• Present trade studies to stakeholders as needed.
• Focus on system trades, quantifiable decision‑making, and mandatory application of real‑world behaviors and military/aerospace specifications.

Qualifications – Must Have

• A Bachelor's Degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of prior 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.
• Experience 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.

Qualifications – Prefer

• 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.
• 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.

What We Offer

• 100% onsite in Tucson, AZ with relocation assistance.
• Salary range: $107,500 – $204,500 (USD) – good faith estimate.
• Comprehensive benefits including medical, dental, vision, life, short‑term and long‑term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, employee scholar program, parental leave, paid time off and holidays.
• Eligibility for annual short‑term and/or long‑term incentive compensation programs depending on level and collective agreement.
• Anticipated application window closing approximately 40 days from posting date.
• RTX values safety, trust, respect, accountability, collaboration, and innovation.
