Qualifications

• BS in Electrical/Mechanical/Systems Engineering or related discipline.
• 5+ years of relevant experience in electrical systems, vehicle electrical engineering, controls, harnesses, power distribution, embedded systems, or a related field.
• Experience with high-voltage and/or electrified vehicle systems, including power distribution, interfaces, cables, protection, grounding, and safety.
• Experience developing or reviewing electrical schematics, wiring diagrams, interface documents, or system block diagrams.
• Knowledge of vehicle communications and networked systems (CAN, CAN-FD, LIN, Ethernet).
• Strong problem-solving, technical writing, presentation, and cross-functional collaboration skills.
• Electrical circuit board experience (Breadboarding, Arduino).
• Understanding of AC theory and power electronics.
• Execution-level architecture with manufacturing processes.

Responsibilities

• Lead electrical architecture definition for new and derivative defense vehicle platforms.
• Translate government, customer, mission, and vehicle requirements into electrical system requirements, architecture decisions, and interface definitions.
• Define vehicle-level electrical topologies, power distribution, network architecture, system boundaries, and low-voltage power-management concepts.
• Architect and integrate high-voltage systems, including batteries, power conversion, propulsion interfaces, high-voltage cables, contactors, service disconnects, grounding, shielding, and safety features.
• Define interfaces among ECUs, sensors, actuators, power electronics, controllers, displays, communication networks, and mission equipment.
• Define low-voltage power distribution, circuit protection, wake-up and shutdown behavior, grounding, connector strategy, and electrical load-management concepts.
• Develop and review schematics, wiring concepts, interface control documents, netlists, block diagrams, and architecture specifications.
• Evaluate commercial off-the-shelf (COTS) and custom technologies, balancing technical performance, mission suitability, supply risk, integration complexity, cost, and schedule.
• Identify and resolve cross-functional electrical issues, including interface conflicts, power-quality concerns, EMC risks, network limitations, thermal constraints, and packaging conflicts.
• Ensure architecture decisions support automotive, defense, functional-safety, cybersecurity, EMC, export-control requirements.
• Support proposals, statements of work, technical volumes, compliance matrices, and customer presentations while providing technical leadership to engineers and suppliers.
• Ensure designs meet applicable automotive, defense, functional-safety, cybersecurity, EMI/EMC, export-control, and ITAR requirements.
