About the Team:
The Guidance, Navigation and Control (GN&C) Subsystems and CoreSim Team is made up of enthusiastic and talented individuals that design and produce the hardware, algorithms, and software required to solve the challenging problems of controlling spacecraft systems in a harsh, zero-g environment.

The selected candidate will report directly to the GN&C Manager within the GN&C Talent Center organization of Lockheed Martin Space.

About the Role:
In this Guidance, Navigation & Control Engineer (Senior, Level III) position, we are seeking an experienced GNC Engineer who will serve as a Line of Sight (LOS) analyst.

The role specifically is looking for a specialist in the subject of optical line of sight (LOS) jitter analysis for precision pointing spacecraft to support multiple satellite buses including, but not limited to, the LM400 and LM2100 satellite series. In addition to knowledge in the field of LOS jitter analysis, the candidate should have familiarity with GN&C subsystem architecture, systems engineering, disturbance modelling, dynamometer testing, space vehicle jitter testing, requirements flow down, early program design and analysis, structural analysis, Damping, Dynamics Modeling, Modeling Uncertainty factors, LOS jitter analysis and time/frequency domain analysis.

Successful applicants generally have at least 3+ years of related experience and may have a post-secondary degree or training in a related discipline, such as Aerospace Engineering or other related field.

The information below reflects the standard job description for this position:

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.

Basic Qualifications

Skill Requirements:
• Possess domain experience in spacecraft controller design and optimization.
• Experience in developing and verifying performance of simulation models in simulation environments using programming tools that include MATLAB/Simulink, C++
