## About the Role

Successful applicants generally have at least 2+ years of related experience and may have a post-secondary degree or training in a related discipline., * Familiarity with Guidance, Navigation, and Control (GNC) subsystems and applications. (i.e. understanding how components such as GPS receivers, IMUs, star trackers, reaction wheels, etc., contribute to spacecraft state estimation and control)

 * Strong written and verbal communications skills

Security Clearance / Work Authorization

 * To meet requirements of the program/customer, this position requires the selected employee to be a U.S. Citizen.
 * Although not required to start, the selected applicant must be eligible to obtain, and maintain, Top Secret with adjudicated SCI Eligibility (i.e. TS/SCI) for long term employment on this program

Desired Skills

 * Bachelor's Degree in Mechanical, Electrical, Aerospace Engineering or other related engineering degree
 * Familiarity with orbital mechanics
 * Familiarity with spacecraft navigation and attitude determination
 * Proficiency in Matlab and STK
 * Experience working with hardware development, including build, test, and integration

## Description

This role will be a valued member of a tight-knit engineering team responsible for a variety of types of GNC (guidance, navigation & control) hardware, potentially including GPSR (Global Positioning System Receiver), RWA (reaction wheel assembly), CSS (coarse sun sensor), ST (star tracker), IMU (inertial measurement unit) or MTR (magnetic torque rod), while supporting multiple programs within LM Space. From procurement, through manufacturing, test, integration and on-orbit operation, you will have the opportunity to work with a variety of subject matter experts to learn on the job. This role also includes a significant amount of collaboration with external entities, i.e. customers and suppliers, and may include periods of necessary business travel., Designs, develops, implements, verifies and tests algorithms to perform guidance, navigation and control of aircraft, spacecraft, launch vehicles and upper stages during powered and coast phases of flight, earth orbit, interplanetary cruise and orbital insertion, as well as during staging events. Navigation functions include the statistical processing of measured data points and their substitution into algorithms simulating physical reality. Guidance functions include the formulation of specific equations and control laws to achieve a desired position in space. Control design and analyses processes consist of the development of the control requirements for aircraft, launch vehicles and/or spacecraft. #spacegnc
