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, batteries, 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, 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.

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 to include any of the following:
  • Power electronics, analog design, mixed‑signal design, or high‑reliability electronics development experience
  • Enterprise / cross‑company multidisciplinary architecture development.
  • Experience with SPICE simulation, modeling tools, and power/analog design best practices
  • Experience evaluating platform power requirements for weapon integration
  • Experiencing building platform roadmaps; evaluating and integrating cutting‑edge technologies.
  • The ability to obtain and maintain a U.S. government issued security clearance is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Qualifications We Prefer

• Advanced Degree such as Masters/ PhD
• TS Clearance
• 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.
• 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.
