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 Transportation business unit, which develops Blue Origin's multiple Blue Moon lander product lines. To further Blue Origin's mission of having millions of people living and working in space, we are building sustainable infrastructure for our transport of crew and cargo from Earth to the lunar surface. As part of a hardworking team of diverse specialists, technicians, and engineers, you will be responsible for developing the models and performing analysis of an integrated fuel cell, balance of plant, and individual components. These models will be used to accelerate development activities, conduct detailed analyses, verify requirements, and explore trade spaces.
