Ursa Major was founded to address a critical shortfall in the U.S. industrial base and bring a new model to aerospace and defense systems: we design and manufacture the world’s leading propulsion systems for space, hypersonic applications, and missile systems. 

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.

The Propulsion Development Team is primarily responsible for the design, execution, and documentation of development and qualification campaigns for Ursa Major’s propulsion systems. This involves test design, data analysis, failure investigation, and risk mitigation for whole propulsion systems as well as development support for programs earlier in their life cycle. Success on this team requires an understanding of rocket propulsion fundamentals, mechanical and fluid systems, strong critical thinking skills, attention to detail, organization, and effective communication across discipline groups.
