At Blue Origin we envision millions of people living and working in space for the benefit of Earth. Were 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 Advanced Concepts and Enterprise Engineering (ACE) supporting Blue Origins mission of millions of people living and working in space for the benefit of Earth. The team fosters innovation and drives engineering workflows of the future shared solutions and standards simplicity and lower costs and manufacturable design.

We believe that to preserve our planet humanity must expand beyond our current limits venturing into space to explore and harness new energy and material pursuit of this vision we invite you to join our Space Resources Program. The Space Resources Program encompasses multiple projects; in this role you will contribute to the current Oasis-1 effort and future initiatives. Were dedicated to developing and demonstrating Prospecting and In Situ Resource Utilization (ISRU) technologies for the Moon Mars and beyond. If our mission resonates with you and you are eager to contribute you could be the perfect addition to our collaborative open-minded and forward-thinking team.

The pace at Blue Origin is brisk with rapid cycles of design analysis and integration aimed at delivering scalable solutions. We need someone who is adaptable proactive eager to learn and uncompromising on safety and quality. Creativity a spirit of innovation and the ability to manage changing requirements are key to thriving on our inclusive open-minded and forward-thinking team. Passion for our mission is required!
