Senior Embedded Systems 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.

Oh, and we're dog friendly!
