Propulsion Design Engineer Jobs in Colorado (NOW HIRING)

The future of aerospace and defense starts here.

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.

The journey to space starts with engines.

Ursa Major was founded to bring a new model to space access: one in which every link in an enormous value chain isn’t limited by those around it. We design rocket engines and propulsion solutions.

Our products and technologies require an extraordinary team. A team that will mold tomorrow’s technologies while deploying today’s best. We are an intrinsically motivated team that has a passion for solving problems and empowering each other every day to develop our skills, knowing that there is always room for growth.

Our advanced aerospace and defense systems depend on reliable, high-performance avionics to ensure mission success. As a Staff Electrical Engineer, you will work with cross-functional design and development teams to architect, design, and verify embedded electronic hardware for a wide range of flight-critical systems, including batteries, power distribution units, guidance, navigation and control (GNC) components, flight termination systems, safe and arm devices, propulsion control, telemetry and other vehicle electronics. In this role, you will lead the development of circuit card assemblies (CCAs) and FPGA-based hardware that interface with sensors, actuators, power systems, and high-speed communication buses. You will be responsible for hardware design from concept through verification, ensuring designs meet demanding aerospace and defense performance, reliability, and environmental requirements. A strong background in mixed-signal electronics, FPGA design, and hardware development for harsh environments is essential. You will also help define and execute hardware verification and validation strategies using industry best practices and customer requirements.
