This role involves end-to-end ownership of flight hardware and ground support systems while collaborating closely with cross-functional mechanical and electrical engineering teams. You will help bridge the gap between electrical and mechanical disciplines, mentor junior engineers, and contribute to establishing engineering standards and tools across the organization. The position offers a highly hands-on, fast-paced environment focused on rapid prototyping, iterative testing, and solving complex technical challenges that advance hypersonic commercial transport.\nResponsibilities\nOwn the electrical power architecture and components for new vehicle development from concept through implementation and testing.\n\nDesign and develop power electronics systems for supersonic and hypersonic aircraft applications.\n\nCollaborate with cross-functional mechanical and electrical engineering teams to architect integrated vehicle power systems.\n\nSupport systems providing electrical, fluid, and mechanical power to critical aircraft components.\n\nServe as a technical bridge between electrical and mechanical engineering disciplines.\n\nDesign flight hardware as well as required ground support and test equipment.\n\nEvaluate, select, and integrate commercial off-the-shelf (COTS) and custom hardware solutions.\n\nWork directly with vendors and suppliers to identify and develop suitable components and systems.\n\nMentor junior engineers and help establish engineering standards, tools, and best practices across the team.\n\nSupport hands-on hardware assembly, integration, troubleshooting, and testing activities.\n\nParticipate in rapid prototyping, iterative development, and fast-paced build/test cycles.\n\nContribute to advancing propulsion and power system capabilities for next-generation hypersonic transport vehicles.\n\nRequirements\nBS Electrical Engineering or Mechanical/Aerospace with significant industry experience working with development of electrical component & systems \n5+ years of experience in multiple of the following areas: Battery design, motor controller design, harness design and fabrication, design for high EMI environments and appropriate mitigations, power conditioning, communication hubs/busses, bus converters, and PCB layout \nPreferred Skills and Experience\nMaster’s degree in Electrical, Mechanical, Aerospace Engineering, or a related discipline.\nDirect experience working with high-voltage DC systems and components (e.g., batteries, motors, generators).\nHands-on experience with HV systems, including proper safety procedures and precautions.\nStrong working knowledge of aerospace systems engineering practices, including requirements development, verification and validation, component qualification and acceptance testing, system diagramming/modeling, and risk management.\nExperience executing hardware test and certification campaigns.\nProficiency with relevant software tools and programming languages such as Python, Capital Harness, Siemens NX/Teamcenter, and Altium Designer.\nExperience with simulation and test tools (e.g., Fluke process meters, ammeters, Simulink, ANSYS).\nFamiliarity with industry standards such as IPC-620, MIL-STD-810, MIL-STD-704, MIL-HDBK-516C, MIL-STD-464D, and DO-160G.\nDemonstrated project experience designing high power (>5kw) electronic components and or distributed systems \nStrong analysis and troubleshooting skills \nExperience working with avionics devices and communication protocols (CAN bus, RS-422, ARINC 825) and connectors (e.g., D38999).\nStrong ability to collaborate across mechanical and electrical engineering domains.\nProven experience contributing to engineering project teams in fast-paced environments.","description_format":"text","description_chars":3892,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Electrical
