Senior Electrical Engineer – Spacecraft Power Systems & Bus Architecture Verified today
What you will do
- Architect and design spacecraft power systems including solar array interfaces, battery charge/discharge regulation, power distribution units (PDUs), and system-level grounding schemes.
- Lead development of the main spacecraft power bus: voltage regulation, load management, protection, and redundancy strategies.
- Perform trade studies and system sizing for battery capacity, solar array performance, and bus architecture optimization.
- Develop schematics, PCB layouts, and cable harnessing for power boards and interface hardware.
- Drive hardware bring-up, functional testing, and fault isolation on power boards and integrated systems.
- Collaborate with systems, mechanical, and thermal engineers to align EPS design with mission requirements and spacecraft constraints.
- Contribute to environmental testing for acceptance and qualification and EMI/EMC compliance for power hardware.
- Coordinate with Launch Providers on interfaces and concept of operations during payload integration, launch pad and waking up in space.
What we are looking for
- B.S. or M.S. in Electrical Engineering or related field.
- 5 or more years of experience designing power systems for aerospace, spacecraft, or other high-reliability platforms.
- Experience with spacecraft power architectures including unregulated and regulated bus designs.
- Strong understanding of power electronics design, including DC-DC converters, battery management systems, and overcurrent/undervoltage protection circuits.
- Knowledge of space-grade components, derating guidelines, and radiation effects on power electronics.
- Proficiency with ECAD tools such as Altium Designer for board design and system schematics.
- Hands-on experience testing and debugging flight or flight-like power hardware in lab and system testbeds.
- Familiarity with power system modeling and analysis tools such as PLECS or SPICE.
- Experience with EPS integration and operations on actual flight programs.
- Familiarity with standards such as NASA-STD-4005, ECSS-E-ST-20-20, or NASA power interface specs.
