• Model, develop, simulate, and analyze launch vehicle, spacecraft, and lander dynamics and control system performance and stability.
• Resolve complex problems pertaining to the design, development, analysis, integration, evaluation, testing, and verification of control systems and 6‑DoF models and simulations.
• Develop, modify, maintain, and improve software simulations, tools, and scripts.
• Periodically analyze HLS partner flight data and present findings to NASA management.
• Create, edit, and debug software written in MATLAB, Simulink, and Simscape.
• Configure, conduct, and analyze 6‑DoF Monte Carlo simulations.
• Conduct trades studies and/or sensitivity analyses related to launch vehicles and spacecraft control.
• Mentor junior engineers in control system modeling, simulation, and analysis.
• Prepare and present technical reports and/or briefings including visualization of results.
• Create and review engineering and software documentation.

A degree in Aerospace, Mechanical or Electrical Engineering or related field from an ABET accredited institution is required. Typical experience requirements are:
PhD with at least 19 years of experience, master’s with at least 23 years of experience, or BS with at least 25 years of experience. Proof of U.S. Citizenship is required.

• Ability to work problems from first principles, including derivation of dynamics equations of motion, both nonlinear and linear, and integrate subsystem models into larger simulations.
• Proficiency modeling, simulating, and analyzing the performance of launch vehicles, spacecraft, and landers in the time domain using parametric, Monte Carlo, and statistical techniques.
• Experience analyzing control stability in the frequency domain (Nichols, Bode, Nyquist, Root Locus, etc.).
• Demonstrated ability to design flight control systems (PID, state space, etc.) and perform actuator allocation (manual jet selection, quadratic programming, pseudo inverse, etc.).
• Modeling of spacecraft components/subsystems such as Thrust Vector Control (TVC) actuators, Reaction Control System (RCS) thrusters, slosh, pogo, rigid and/or flexible body dynamics.
• Programming in MATLAB, Simulink, and C/C++, including debugging and improving simulation tools.
• Experience performing software development, verification, and validation.
• Experience performing trade studies, sensitivity, and/or Monte Carlo simulations and analyses related to the control of launch vehicles and/or spacecraft.
• Strong written and oral communication, interpersonal, and problem‑solving skills.
• Experience leading and/or mentoring junior engineers.
• Detail‑oriented and self‑motivated, able to work independently and collaboratively with teams locally and remotely.

• Experience modeling, simulation, and analysis of spacecraft rendezvous, proximity operations, and docking and/or landers.
• Experience modeling and simulating manual control of spacecraft, including cont rollability, transfer function models, Cooper‑Harper ratings, and paper pilot modeling.
• Programming in other languages such as Python, Simscape Multi‑body.
• Familiarity with trajectory and orbital dynamics.
• Experience creating animations/visualization from 3‑DoF/6‑DoF simulation results using tools such as Unreal Engine, Satellite Tool Kit (STK), etc.
• Model‑based design experience.
