CAD Librarian II

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.

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.

As a CAD Librarian II at Ursa Major, you will play a critical role in developing, maintaining, and managing the CAD library for Commercial Off-The-Shelf (COTS) components, standard fittings, and various other components. This position ensures that all CAD models are accurate, up-to-date, and easily accessible for our engineering and design teams. The ideal candidate will have experience in the aerospace industry, strong attention to detail, and proficiency with CAD and PLM systems.

You will work closely with design engineers and other stakeholders to establish and enforce standards, support data integrity, and streamline the use of CAD assets across projects.

You will work cross-functionally with engineers, program managers, manufacturing, and customer integration teams to ensure that product definitions are accurate, traceable, and physically representative throughout the product lifecycle. This is a high-impact role where attention to detail, technical fluency, and process rigor are essential.
