About this role

 

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. 

Ursa Major is currently looking to fill a role in propellant development for SRM systems. This call seeks an individual skilled in research and development to support analysis of solid rocket motor production materials. The ideal candidate will have hands-on experience with formulation or polymer chemistry as well as a strong commitment to safety and quality. This role involves assisting in the setup, operation, and maintenance of hazardous and technical process equipment designated for energetics processing. Individual will be trained to handle energetic/explosive materials. Additional work in expanding experimental development and analysis would be a bonus.
