Junior Spacecraft Guidance, Navigation and Control ...

In this position you will work with our team of engineers and our NASA customers to support human spaceflight programs at NASAu2019s Johnson Space Center, such as Gateway, the Orion crew vehicle, and the International Space Station. You will assist in the development of Guidance, Navigation, and Control (GNC) subsystem Flight Software (FSW) and integrated Flight Hardware (FHW). This may also include integration with human-computer interfaces, flight computer data interfaces, custom development and integration tools, and spacecraft and space mission environment simulations. Candidates must have solid software development, integration, and testing skills; strong communication abilities, initiative and an aptitude for hands-on problem solving and troubleshooting. u00a0 A Junior Spacecraft Guidance, Navigation, and Control (GNC) Engineer typically focuses onu00a0supporting the design, analysis, and simulation of systems that manage a spacecraft's trajectory and attitude. At this level, you will work under the mentorship of senior engineers to develop algorithms and validate system performance through rigorous testing. Key Responsibilities: + Algorithm Development:u00a0Assist in designing and implementing control loops for attitude determination and position control. + Modeling & Simulation:u00a0Develop and maintain high-fidelity 6-DOF (degree-of-freedom) simulation models for vehicle dynamics, sensors (e.g., star trackers, GPS), and actuators (e.g., reaction wheels, thrusters). + Performance Analysis:u00a0Conduct Monte Carlo simulations and frequency-domain stability analyses to ensure compliance with mission requirements. + Testing & Verification:u00a0Support hardware-in-the-loop (HITL) and software-in-the-loop (SIL) testing to validate GNC flight software. + Mission Operations Support:u00a0Analyze flight telemetry data to troubleshoot anomalies and assess on-orbit performance. + Documentation:u00a0Create technical reports, design review presentations, and interface control documents (ICDs). Required Qualifications: u00a0 + Education:u00a0Bacheloru2019s degree in Aerospace, Software, Mechanical, or Electrical Engineering, Computer Science, or a related field (e.g. Physics,Math). + Technical Knowledge:u00a0Strong foundation in orbital mechanics, classical and modern control theory, and state estimation (e.g., Kalman filtering). + Software Skills:u00a0Proficiency inu00a0MATLAB/Simulinku00a0is standard; experience with C/C++ and/oru00a0Pythonu00a0for algorithm implementation is highly valued. + Communication:u00a0Ability to collaborate effectively in multidisciplinary teams and present findings to stakeholders. Desired Qualifications: u00a0 + Experience with Government Off-The-Shelf (GOTS) and/or Commercial Off-The-Shelf (COTS) mission simulation and analysis software tools, such as, NASAu2019s TRICK, NASAu2019s GMAT, NASAu2019s Copernicus, AGIu2019s STK, and/or ai Solutionsu2019 FreeFlyer. + Knowledge of GNC HW components such as GPS Receivers, Star Trackers, Inertial Measurement Units, Gyroscopes, Magnetorquers, Control Moment Gyros, Reaction Wheels, and/or cold gas jet thrusters. + Familiarity with software configuration management systems such asu00a0Git , Bitbucket, Subversion (SVN), etc. + Experience with software issue tracking and delegation tools such as Jira, GitLab, GitHub, Trello, etc. Citizenship or lawful permanent resident required due to federal position.
