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! 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 Rendezvous Navigation Engineer on Lunar Transportation, you will directly contribute to the development of the on-board rendezvous navigation software for our crewed and uncrewed lunar vehicles. The products developed provide Lunar Transportation lander vehicles with Software products to enable unprecedented crew and mass to surface capabilities. You will directly impact the history of space exploration and will require your dedication and attention towards safe and reliable spaceflight. 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 system that will return humans to the Moon and extend human presence permanently beyond the bounds of Earth. We are looking for our engineers to apply their technical expertise, leadership skills, and dedication to quality to positively impact safe human spaceflight. Passion for our mission and vision is required! Responsibilities include but are not limited to: Contribute to the development of rendezvous relative navigation algorithms, culminating with its deployment onto a target platform for realtime execution Verify the navigation software implementation via closed loop and open Monte Carlo, and unit testing. Contribute to the development and deployment of embedded software, including sensor I/O Support the testing of embedded navigation software including sensor and sensor-data management using MATLAB/Simulink, C, and C++ Support the development of vision-aided navigation and sensor fusion algorithms for relative spacecraft navigation Support the development and execution of component-level navigation test programs, including sensor characterization, sensor modeling, and integrated on-vehicle testing Embody the Blue Origin leadership principles Minimum Qualifications: B.S. or M.S. or equivalent experience in computer science, aerospace engineering, or related technical field with 3+ years of proven experience Shown experience in synthesis of state estimation algorithms and Kalman filters for spacecraft navigation Proven experience with build systems, version control, and testing methodologies Strong software design and development skills with emphasis in C++ and Simulink/MATLAB. Including skills in debugging and performance optimization Experience with hardware and software integration and testing, including experience with sensor device drivers and I/O Experience in verification and test of embedded software and systems Operational knowledge of inertial and relative navigation sensors Ability to earn trust, maintain positive and professional relationships, and contribute to a culture of inclusion Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum Preferre
