Guidance Navigation and Control (GNC) designs the constellation for good coverage and space safety and develops the systems that control and maneuver each satellite as they ascend from injection to operational orbits merge into the constellation flow and station-keep relative to neighbors. Every spacecraft is ready and able to maneuver at any time to avoid other satellites or space debris if a close pass threatens. The navigation system provides precise positioning in real-time and supports forecasting future orbital state taking into account planned maneuvers and other effects.

Key job responsibilities
This role is for a Software Development Engineer who will design architecture and implementation of various enhancements and integrations for our constellation management system and flight dynamics services. Youll build these systems using the latest AWS technologies and best-in-industry software engineering practices.

Our team is creating the algorithms and software that plays a central role in situational awareness for Leos satellites and coordinates with external space agencies and operators to maintain safe orbital trajectories and avoid collisions with the tens of thousands of pieces of space debris.

A day in the life
This is an opportunity to play a significant role in the design of constellation management system with challenging performance requirements. The large integrated constellation brings opportunities for advanced capabilities that need investigation and development. Scale also puts emphasis on engineering excellence so our tools and methods from conceptualization through manufacturing and all phases of test will be state of the art as will the satellite and supporting infrastructure on the ground.
