Sr. Navigation Engineer (8-12 yrs)

The team at Advanced Space is leading humanity back to the Moon and pioneering innovative solutions in the space industry. Based in Westminster, Colorado, this incredible team is looking for a Sr. Navigation Engineer with 8-12 years of experience who’s eager to push the state of the art in spacecraft navigation technology. This position is responsible for leading development efforts, supporting a technically diverse team, and conducting detailed analyses of navigation technology and missions. The ideal candidate will be an experienced professional who can drive innovation, mentor junior engineers, and support spaceflight operations. This role will be based in Westminster, Colorado, and the ideal candidate will have a passion for the exploration, development, and settlement of space. This position is open to U.S. Persons only (U.S. citizens, or lawful permanent residents), as required by applicable laws and regulations.

Candidates must be authorized to work in the U.S. without the need for current or future sponsorship. Responsibilities Lead spacecraft navigation for all mission phases, including formulation, tracking architecture development, estimation approach, and operations. Develop and validate advanced Kalman filter configurations for complex regimes (multi-body, low-thrust, weak observability). Serve as primary navigation lead for flight operations operations prep, including console support, real-time OD, and anomaly response. Architect navigation solutions that account for mission design, GNC, communications, and ground system constraints. Own navigation products for major reviews, clearly communicating performance, trades, and risks. Mentor junior navigation engineers in OD, filter design, measurement modeling, and operations best practices. Drive improvements to navigation procedures, tool setups, and standard operating practices. Support BD and IRAD by shaping navigation concepts, contributing to proposals, and defining new mission and capability concepts. Required Qualifications 8–12 years of professional experience in spacecraft navigation, orbit determination, or closely related flight dynamics roles. Bachelor’s degree in Aerospace Engineering, Systems Engineering, or related field. Demonstrated leadership of OD campaigns or major navigation tasks, including filter setup, force models, and tracking strategies. Proven ability to design and adapt Kalman filters for new dynamical and tracking regimes, including dynamic, bias, stochastic, and consider parameters.
