Spacecraft Power Electronics Engineer

Katalyst is an American technology company focused on dynamic space operations.  We are building a fleet of dual-use multipurpose robotic space vehicles to create the future where maneuvering, upgrading, refueling, resupply and exploration are as routine as they are on Earth. Getting to space and overcoming the gravity well is only half the story. What you do there is the future. We are not building the trains. We are building the machines that lay down the tracks. By developing the foundational capabilities that make sustained, responsive operations possible, we enable a new era of space exploration that strengthens national security and ensures freedom of action in an increasingly contested domain.

Working at Katalyst is intense, hands-on, and deeply rewarding. You’ll take real ownership and see your work move from concept to operations in an environment where the problems are hard and the impact is real. We value humility, craftsmanship, and doing things the right way, even when it’s harder. You’ll work closely with thoughtful, driven teammates who push each other to do their best. 

1. → Bachelor’s degree in electrical engineering or equivalent field.
2. → 3-5 years of experience designing, testing, or integrating power electronics, spacecraft EPS hardware, battery/solar power interfaces, or closely related high-reliability power systems.
3. → Strong understanding of switch-mode power supply design, DC/DC converter architectures, compensation/stability, magneticsselection, protection circuitry, and practical power electronics debugging. 
4. → Experience designing ormodifying schematics and PCB layouts for power electronics, including high-current routing, grounding, thermal considerations, creepage/clearance, current sensing, and EMI/EMC-aware layout practices. 
5. → Proficiency in Altium or a similar ECAD tool for schematic capture, PCB layout review, design release, and documentation.
6. → Exposure to spacecraft or embedded-system power architectures, including power distribution, load switching, battery management interfaces, solar array regulation, or power telemetry.
7. → Exposure to common digital communication standards (SPI, I2C, UART, CAN, Ethernet) and mixed-signal design best practices for telemetry, control, and power-system interfaces.
8. → Hands-on experience with hardware bring-up, bench testing, and debugging using oscilloscopes, electronic loads, power supplies, DMMs, logic analyzers, and related lab equipment.
9. → Experience writing or executing test procedures, documenting results, and driving board- or component-level troubleshooting through root cause and corrective action.
10. →Experience integrating power electronics with other spacecraft or embedded subsystems; exposure to environmental testing such as thermal vacuum or vibration is a plus but not required.
