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 Advanced Concepts and Enterprise Engineering (ACE), supporting Blue Origin’s 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. The GN&C Modeling and Simulation Engineer supports integration, verification, analysis, and evaluation of spacecraft GN&C algorithms, vehicle performance, and mission design. Candidates have a strong background in the architecture and capabilities of spacecraft guidance, navigation, and control algorithms, and are able to leverage modern design tools to support rigorous verification of algorithm performance and robustness. A deep understanding of physical modeling, including classical dynamics, astrodynamics, aerodynamics, and propulsion systems along with model-based engineering software development experience is highly desired.
