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 diverse team of problem solvers as we add new chapters to the history of spaceflight! This role is part of the Lunar Permanence business unit. To further Blue Origin's mission of having millions of people living and working in space, we are building the sustainable infrastructure for our transport of crew and cargo from Earth to the Lunar Surface. As part of a diverse and hardworking team of engineers, you will join our Mission Design and Ground Navigation team within the Guidance, Navigation, and Controls (GN&C) IPT. You will share in the team's impact on all aspects of the development of trajectories for spacecraft from Earth to the Moon! You will also develop mission scenarios, ground-based navigation and orbit determination software, flight dynamics systems, configuration trade studies, and simulation capabilities. Expect to be a technical contributor to one or more programs within Lunar Transportation. In this capacity, you will be responsible for exemplifying best practices, balanced technical judgment, and superior work ethic. You will work directly with NASA and our National Team Partners as part of the Human Landing System (HLS) Sustaining Lunar Development (SLD) program. You will play a key role in developing the Lunar Transportation system that will return humans to the Moon and extend human presence permanently beyond the bounds of Earth. 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!
