Senior Power Electronics Engineer - Denver, Colorado | On-site
Opportunity SummaryJoin a venture-backed aerospace company developing advanced spacecraft platforms for future commercial and government missions. As the company builds flight-ready hardware, this role will lead the electrical power architecture that distributes, protects, and manages energy across every spacecraft subsystem. This is a hands-on engineering position focused on power electronics, battery systems, electrical distribution, actuator drive electronics, and hardware validation. You'll own the spacecraft power system from battery management through power conversion, distribution, monitoring, and fault protection while working alongside firmware, mechanical, and systems engineering teams.
About UsWe are an early-stage aerospace company developing integrated spacecraft technologies that combine advanced hardware, embedded software, and precision engineering. Engineers have broad ownership and the opportunity to influence products from initial architecture through flight qualification.
Job Duties- Own spacecraft electrical power architecture from battery through power distribution.
- Design battery management systems and electrical protection circuits.
- Develop power conversion hardware including DC-DC converters and switching electronics.
- Design actuator drive electronics and high-current switching circuits.
- Implement fault protection, current limiting, and electrical redundancy strategies.
- Develop power telemetry and health monitoring systems.
- Create schematics, PCB layouts, manufacturing documentation, and design reviews.
- Perform board bring-up, validation, troubleshooting, and environmental testing.
- Analyze electrical performance using laboratory instrumentation.
- Collaborate with firmware, systems, and mechanical engineering teams throughout product development.
Qualifications- Bachelor's degree in Electrical Engineering or equivalent experience.
- 5+ years designing power electronics or electrical power systems.
- Experience with DC-DC converters, switching power supplies, and power distribution.
- Experience developing lithium-ion battery systems and battery management.
