Senior GSE Design Engineer

Berthoud, Colorado
The journey to space starts with the 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 who will mold tomorrow’s technologies while deploying today’s best. We are comprised of intrinsically motivated individuals who have a passion for solving problems and empower each other every day to develop our skills, knowing that there is always room for growth.

Ursa Major’s team moves fast and does a lot with little. A GSE Design Engineer is responsible for selection and design of the systems needed to test everything from an individual rocket component up to a full rocket engine. Components being tested range from valves, regulators, actuators, pumps, igniters, and transducers. Additionally, designers are responsible for the layout of test facilities to ensure they are safe and compliant with all local, state, and federal requirements.  We expect these engineers to be self-starters and good at designing tests systems. Hands-on experience is required.
This role will report into the test operations organization of Ursa Major.
Colorado law requires us to tell you the base compensation range of this role, which is $95,000 - $150,000, determined by your education, experience, knowledge, skills, and abilities. What we can’t quantify for you are the exciting challenges, supportive team, and amazing culture we enjoy. Click here for more information about our awesome benefits.
