About the Job

Requirements

  • Bachelor’s degree in Electrical Engineering or a related field; an MS or PhD is preferred.
  • A minimum of 8 years of experience in power electronics, analog design, mixed-signal design, or high-reliability electronics development.
  • Effective subject-matter-expert negotiation across disciplines.
  • Knowledge of modeling languages VHDL-AMS/MAST and State-AMS, including mixed-signal and state-aware models.
  • Mastery of harness effects, power quality, electromagnetic interference/electromagnetic compatibility, and signal integrity.
  • 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, and Ethernet/TSN.
  • Ability to learn and apply new technologies and prototype cutting-edge solutions.
  • Ability to negotiate with cross-discipline subject-matter experts and mentor P1–P3 engineers.
  • Ability to collaborate and align with internal and external teams.
  • Ability to present trade studies to stakeholders as needed.
  • 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 varying 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 and analog design best practices.
  • Must be able to obtain and maintain a U.S. Secret clearance.
  • Typically requires a university degree or equivalent experience and at least 8 years of relevant experience, or an advanced degree in a related field and at least 5 years of experience.
  • For engineering or other technical positions, typically requires a degree in science, technology, engineering, or mathematics and at least 8 years of relevant experience.

Responsibilities

  • 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 with performance, cost, producibility, and environmental constraints.
  • Assess and address designs at varying maturity levels, including 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, radio frequency, modeling and simulation, guidance, navigation and control, 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.

Desired Qualifications

  • Experience with missile systems, guidance electronics, harsh-environment power systems, or seeker/power integration.
  • Hands-on experience with laboratory bring-up, prototype testing, instrumentation, and failure analysis.
  • Understanding of electromagnetic interference/electromagnetic compatibility mitigation, grounding strategies, and system-level power integrity.
  • Experience in program leadership, technical direction, or multidisciplinary coordination.
  • Familiarity with model-based engineering, requirements management, and digital engineering practices.

About the Company

RTX

Manufactures jet engines, avionics, missiles

RTX operates in aerospace and defense with three main units: Pratt & Whitney jet engines, Collins Aerospace avionics and flight systems, and Raytheon defense systems. Jet engines provide thrust for commercial and military aircraft, avionics manage cockpit controls and navigation, and Raytheon builds missiles, radar, and sensing platforms. It differentiates itself by offering an integrated, end-to-end portfolio across both commercial aviation and national defense under one corporate roof, built on the legacy of Raytheon and UTC. Its goal is to help customers fly more efficiently and protect nations by advancing propulsion, electronics and defense tech for civilian and security needs.
