Senior Spacecraft Power Electronics Engineer

Katalyst Space Technologies•Broomfield, CO

6h•$140,000 - $180,000

About The Position

We build robotic spacecraft that enable dynamic space operations, creating a future where maneuvering, upgrading, refueling, 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 activity 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.

Requirements

Pride in work: You hold yourself to a high bar. You produce designs, documentation, and analyses that are correct, detailed, and ready for scrutiny.
Humility: You take on new challenges, learn from others, and grow. You seek out missing context, ask good questions, and course-correct quickly with new information.
Technical intuition and mastery: You understand power electronics at the component level and how that integrates in and impacts spacecraft systems at the architecture level.
Bachelor’s degree in electrical engineering, or equivalent field
7+ years’ experience with spacecraft or high-reliability power electronics
Prior ownership of a spacecraft power system or major power subsystem
Experience defining power system architecture, not just implementing designs
Extensive experience with hardware bring-up, failure analysis, and corrective action
Direct experience leading qualification and acceptance testing (TVAC, vibration, etc.)
Proven track record identifying and mitigating technical and integration risks
Experience leading cross-functional integration with avionics and other spacecraft subsystems
Experience setting design rules, test strategies, and review criteria
Must be willing to work extended hours and weekends as needed.

Responsibilities

Own iteration of Katalyst’s spacecraft power system design, including schematics, board layouts, and interface definitions, to improve performance and complete feature upgrades.
Lead operation of power system hardware during qualification testing, working directly with test engineers to execute thermal vacuum and vibration qualification test campaigns.
Own integrated functional testing of power systems hardware with other spacecraft subsystems.
Plan and execute targeted stress and performance testing, exercising hardware to design extremes through targeted performance testing.
Define and plan design changes for feature or architecture improvement of the spacecraft power system with respect to future mission requirements.
Mentor junior engineers
