About The Position

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! This role is part of Blue Origin Operations, which is comprised of Integrated Supply Chain, Test Operations, Safety, Quality, and Mission Assurance. This includes Manufacturing and Supply Chain support across all Blue Origin facilities. As part of a dynamic and dedicated team of Mechanical and Fluid Engineers, you will play a crucial role in developing systems to test rocket engines, components, and integrated space flight vehicles. As a Ground System Fluid/Mechanical Engineer II, you will contribute to all aspects of test stand design across the full system lifecycle — designing fluid and structural systems for test facilities, supporting supplier coordination, and helping bring new test systems from concept through commissioning. You will grow your technical expertise while delivering meaningful work on world-class test infrastructure under the guidance of senior engineers. Passion for our mission and vision is required!
