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 supports the development and operations of New Glenn, a single-configuration, heavy-lift orbital launch vehicle capable of routinely carrying people and payloads to low-Earth orbit, geostationary transfer orbit, cislunar, and beyond. Its first stage is fully reusable, and the vehicle was designed from the beginning to be human-capable.

The responsibilities of this position will be analysis intensive, primarily supportive of development and verification of launch vehicle component and vehicle thermal and fluid environments and performance requirements.

You will implement aerothermal, rocket plume heating, and natural environments during all phases of flight. You will own the documentation and maintenance of analysis inputs, models, and results in reports and data books.

We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required!
