The Engineering andScience Services and Capabilities Augmentation (ESSCA) contract providesengineering, scientific, and technical support to NASA Marshall Space FlightCenter (MSFC) in Huntsville, AL. Our Guidance, Navigation, and Control(GN&C) team is a high performing group executing challenging tasks todesign and integrate GN&C systems for projects ranging from CubeSats toNASA’s Space Launch System (SLS).

Working independently and in an integrated, collaborative team,your responsibilities would include:

  • Analysisof vehicle and multi-body dynamics, equations of motion, and trajectories toassess contact and clearance during liftoff, separation, and jettison events

  • Modelingascent and in-space environments, errors, disturbances, algorithms, sensors,actuators, and mechanisms

  • Simulateand analyze nominal, contingency, and failure scenarios during ascent andin-space flight

  • Developalgorithms and tools for GN&C analysis and design


Degree inAerospace, Mechanical or ElectricalEngineering or related field from an ABET-accredited university is required.Typically, educational requirements are the equivalent of a Ph.D. with a minimum 4 years of experience; Masters with at least 8 years of experience, or a BS with at least 10 years of experience.

Skills and experienceshould demonstrate:

  • Experience with multi-body,multi-degree of freedom analysis and simulation. Experience with TREETOPS, CLVTOPS, andcontact / clearance analyses is highly desired.

  • Proficiency in FORTRAN, MATLAB, C, Python.

  • Knowledge of flight mechanics andorbital mechanics.

  • Experience in GN&C algorithmdevelopment and simulation.

Strongcommunication, interpersonal skills, and independent problem solving arerequired.
