Senior Electrical Engineer, Avionics

Katalyst Description: Katalyst is an American technology company focused on d ynamic space operations . We are building a fleet of dual-use multipurpose robotic space vehicles to creat e 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. Katalyst Culture: 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. Benefits: Stock options & equity Medical, dental, and vision coverage 401(k) Unlimited PTO Catered lunches What You’ll Do Own flight avionics architecture and detailed electrical design for upgrade modules from concept through qualification, integration, launch, and on-orbit operations. Design, analyze, and release spacecraft electronics including processor/compute boards, power conversion and distribution interfaces, sensor/actuator interfaces, communications interfaces, and supporting analog/digital circuitry. Develop electrical schematics, component selections, interface definitions, grounding/bonding approaches, and board-level requirements; partner with PCB layout and manufacturing through build and bring-up. Drive avionics integration across flight software, GNC, power, communications, propulsion, robotics, and payload systems, resolving electrical and data-interface issues at the spacecraft level. Plan and execute board bring-up, functional test, environmental qualification, EMI/EMC testing, hardware-in-the-loop testing, and spacecraft-level integration; lead anomaly investigation and root-cause closure. Perform and review worst-case circuit analysis, power and signal integrity analysis, timing/bus analysis, derating, reliability assessments, and radiation-informed part selection appropriate to mission needs. Create high-quality engineering documentation and technical baselines, and contribute to major design reviews and flight readiness decisions. What We’re Looking For Required Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline. 5-8 years of experience designing and delivering complex electrical or avionics hardware for spacecraft, aerospace, defense, robotics, or other mission-critical systems. …
