Sentinel - Hypersonic Testbed GN&C Engineer
$31,200–$31,200 year
On-siteHuntsville, Alabama, United States or Roy, Utah, United States
Job Summary
Develop Hypersonic Testbed Guidance Navigation and Control (GN&C) algorithms, including PID controller design, gain scheduling, and optimal control techniques, to mature existing tools and tune autopilots for Exoatmospheric and Endoatmospheric flight. Conduct covariance analysis, circular error probable assessments, and trajectory evaluations while modeling 6 degrees of freedom vehicle dynamics and missile components using C++ and MATLAB. Collaborate on engineering reviews, milestone planning, and Agile development cycles to generate flight-ready software from high-level specifications, ensuring consistency across multidisciplinary teams. Work within a 9/80 schedule in Huntsville, AL or Roy, UT, supporting the Sentinel Program's development and deployment of ICBM launch control systems.
