Job Description

We are seeking a highly motivated Propellant Mixing Technician to play a critical role in supporting cutting-edge rocket propulsion research and development. This position will focus on providing hands-on technical support for small to large scale propellant mixing processes and solid rocket motor testing. The ideal candidate will have general mechanical aptitude to use, repair, and maintain test hardware and instrumentation relevant to solid rocket motor live fire testing. Additionally, the role may involve mechanical and sensitivity testing of solid propellant samples. While the primary focus is on technical support, a working knowledge of solid propellant formulation, characterization, and testing is highly desirable to facilitate collaboration with propellant scientists. The successful candidate is an eager learner and strong communicator who puts safety first and works well with those from diverse backgrounds.
