Senior Test Engineer

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 Engineer, Solid Missile Systems Location: Galeton & Berthoud, Colorado

Ursa Major develops, manufactures, and tests solid rocket motors for modern defense applications. We are building a high-performance engineering organization focused on designing and operating the ground systems that enable safe, repeatable, and scalable propulsion testing.

As a Senior Test Engineer, you will own the design, integration, build, and lifecycle support of test infrastructure used for propulsion testing. This includes static fire test stands, fluid-mechanical systems, ground support equipment (GSE), and the integrated controls, instrumentation, and data acquisition systems required to execute tests safely and repeatably.

This is a hands-on role working directly at rocket test sites and in remote field locations, where you will build, assemble, modify, and troubleshoot mechanical, fluid, and controls-based test systems. You’ll collaborate closely with test technicians, propulsion engineers, and operations teams to execute development and qualification test campaigns and resolve system-level issues in real time.

Key Responsibilities

Integrated Test Systems & Infrastructure Ownership

• Design, develop, commission, and sustain scalable propulsion test stands and test infrastructure supporting multiple solid rocket motor programs ranging from early R&D through qualification and production acceptance testing.

• Design and integrate fluid-mechanical systems including high-pressure gas systems, pneumatics, hydraulics, and remotely operated ground support equipment.

• Design and maintain industrial electrical and controls systems for propulsion test operations, including low-voltage power distribution, grounding/bonding, interlocks, PLC-based automation, sequencing logic, and facility electrical integration.

• Support instrumentation and data acquisition systems including sensor integration, signal conditioning, calibration strategy, distributed DAQ architecture, data integrity validation, and control room interfaces. <span data-ccp-props="{"201341983":0,"335559685":360,"3
