We are seeking a Hardware Development Engineer I to join our Power Electronics team. In this role, you will be a contributor helping to solve difficult hardware engineering problems related to high-power electronics systems. You will design, develop, and validate power electronics boards from concept through production, working on high-voltage DC systems that push the boundaries of performance, reliability, and efficiency. This position requires an engineer who demonstrates strong technical skills in power electronics design, schematics, power electronics PCBA layout, hardware bring-up testing and troubleshooting. Key job responsibilities • Assist in the Design, develop, and test multi-layer power electronics board for high-voltage DC systems, from initial concept through volume production release. • Support schematics development, PCBA layout, prototyping, DFM, board bring-up testing, drawings, bill of materials, and supporting design documentation • Support development of test plans that validate designs against DO-160 and DO-274 standards, ensuring electromagnetic compatibility, environmental resilience, and functional safety. • Create and maintain high-quality design documentation including schematics, specifications, analysis reports, and test results. • Conduct design reviews with teammates and cross-functional teams. • Apply system-level thinking to understand how power electronics subsystems integrate with and influence the broader product architecture. A day in the life You support the design and delivery of power electronics hardware, making sound trade-offs between performance, cost, manufacturability, and schedule. Your test plans thoroughly validate designs and efficiently address system integration challenges. You think in terms of the system, not just individual components, and proactively work to improve the overall product architecture. Your work is consistently high quality, meeting safety, regulatory, and reliability standards. About the team The Electric Propulsion Subsystem (EPS) organization conducts technology research, design and development of the power system for Prime Air’s drones. We are responsible to deliver an EPS and hardware components that safely supports 15-minute drone delivery and is certifiable by the FAA and EASA regulators. Our work spans the full product lifecycle, from early-stage research and concept development through detailed design, prototyping, testing, and certification support. The EPS is a critical system enabling Prime Air’s autonomous delivery operations, providing the electrical power generation, storage, distribution, and propulsion capabilities required for safe and reliable flight.
