Proof of U.S. Citizenship is required.
Required Skills:
- Ability to work problems from first principles, including derivation of dynamics equations of motion, including both nonlinear equations and linear state equations 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++. This includes debugging and improving the efficiency of simulation tools.
- Experience performing software development, verification, and validation.
- Experience performing trade studies, sensitivity, and/or Monte Carlo simulation and analyses related to the control of launch vehicles and/or spacecraft.
- Must be detail oriented and self-motivated that can work independently taking projects from start to finish without much oversight.
- Must also be able to work collaboratively with other team members both locally and remote at other facilities or vendors.
- Strong written and oral communication, interpersonal, and problem-solving skills.
- Experience leading and/or mentoring junior engineers.
Desired skills/experience:
- Experience with modeling, simulation, and analysis of spacecraft rendezvous, proximity operations, and docking and/or landers
- Experience modeling and simulating manual control of spacecraft including but not limited to controllability, transfer function models, Cooper Harper ratings, and paper pilot modeling.
- Programming in other languages such as Python, Simscape Multi-body.
- Familiarity with and an understanding of trajectory and orbital dynamics.
- Experience with creating animations/visualization from results of 3-DoF/6-DoF simulations using tools such as Unreal Engine, Satellite Tool Kit (STK), etc.
- Model based design experience.
