Senior Test Technician

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.

Senior Test Technician – Solid Rocket Motors Ursa Major is seeking a senior-level, hands-on, and safety-conscious Test Technician with a dual focus: Lead test site infrastructure and equipment buildout and maintenance, and Executing static fire campaigns for solid rocket motors with precision and urgency. This role is ideal for an experienced process, fabrication, or GSE technician with a strong foundation in industrial maintenance, mechanical systems, and infrastructure buildout — who also plays a direct, high-impact role in test execution. You'll work with hazardous, energetic materials and high-performance propulsion systems in a fast-paced, outdoor, and dynamic environment.

Success demands a disciplined approach to safety, technical excellence, and the ability to perform under pressure. If you're mechanically inclined and thrive in high-stakes, fast-moving settings, this role offers a direct path to contributing to cutting-edge rocket engine development through hands-on test operations.
