Jacobs GN&C Navigation Engineer in Huntsville, Alabama

GN&C Navigation Engineer


The Space Launch System (SLS) is a key component in NASA’s Journey to Mars. Working side by side with our Marshall Space Flight Center partners, the engineers, scientists, and technicians of the Jacobs Space Exploration Group (JSEG) are helping to prepare SLS for flight and to enhance SLS for the future!

Supporting the Guidance, Navigation, and Mission Analysis Branch, our team develops the sensors, algorithms, and software for SLS to know where it is and how to get where it’s going. Our Navigation team is looking for someone to analyze and model the behaviors of sensors and systems, to develop tests and analyze data to validate and enhance our understanding of those systems, and to incorporate that knowledge into assessments of system capabilities.

JSEG offers a partnership in which you can grow personally and professionally within a framework of strong leadership, competitive compensation, and rewarding career paths. Come join our team on the Engineering Services and Science Capability Augmentation (ESSCA) contract whose work is destined to have a long-range effect on future generations!
