CesiumAstro develops advanced communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We are seeking a Power Electronics Engineer II to join our spacecraft payload development team.
In this role, you will contribute across the entire development lifecycle of next-generation power electronics hardware for satellites and space power systems payloads. Responsibilities span from defining power system architectures and conducting trade studies to detailed circuit design, simulation, printed circuit board (PCB) layout, verification and integration testing, and manufacturing support. You will work in a dynamic, cross-functional environment with hands-on, interactive, and autonomous work opportunities.
Key responsibilities include:
- Design and development of analog and power electronics for space applications
- Power stage design for DC-DC power converter topologies
- Schematic capture and PCB layout using industry-standard tools
- Electronics testing and troubleshooting using laboratory instruments
- Analysis and simulation of power systems
- Collaboration with cross-functional teams throughout the development lifecycle
- Manufacturing support and integration testing
Requirements:
- Bachelor of Science (BS) degree or higher in Electrical Engineering from an accredited university
- Minimum 2 years of experience designing analog and power electronics
- Experience with power stage design of basic DC-DC power converter topologies (discrete linear regulators, Buck, Boost, Buck-boost)
- Knowledge of voltage mode control and peak current mode control theory for DC-DC converters
- Experience with electronics schematic capture and PCB layout tools (Altium, OrCAD, Allegro, Xpedition)
- Hands-on experience testing and troubleshooting electronics and power converters using oscilloscopes, spectrum analyzers, electronic loads, and signal generators
- Experience with analysis and simulation tools (SPICE, LTSPICE, SIMetrix/SIMPLIS, PLECS, Simulink, MATLAB, MathCAD, ANSYS Q3D, SiWave, HyperLynx)
- Excellent written and verbal communication skills
Preferred Experience:
- Master of Science or PhD in Electrical Engineering with power electronics research focus
- Board-level power integrity simulation experience (Ansys SiWave, HyperLynx)
- Power magnetics modeling, design, and laboratory characterization
- Control loop modeling and laboratory characterization
- Knowledge of GaN or SiC wide bandgap power semiconductor devices
- Programming skills for hardware test and data processing (Python, MATLAB)
Note: Applicant must be a U.S. citizen, lawful permanent resident, conditional resident, asylee, or refugee, or eligible to obtain required authorizations from the U.S. Department of State due to space technology export regulations.
