SLS Dynamics, Controls, Modeling, Simulation, and Analysis Subject Matter Expert (GN&C SME)
Position Description
The Amentum Space Exploration Division (ASED) Guidance, Navigation, and Control (GN&C) team is a high performing group executing challenging tasks to design and integrate GN&C systems for projects ranging from CubeSats to NASA’s Space Launch System (SLS).
We are searching for highly qualified candidates to remotely support the design and development of the SLS rocket in the Control Systems Design and Analysis branch at NASA’s Marshall Space Flight Center half time as a Dynamics, Controls, Modeling, Simulation, and Analysis Senior Engineer. This exciting work will serve as a critical step in sending humans back to the Moon, Mars, and beyond!
Responsibilities include but are not limited to:
Model, develop, simulate, and analyze launch vehicle and spacecraft dynamics (including aerodynamics, flexible body, slosh, actuators, etc.), control systems, performance, and stability in both the frequency and time domains with varying levels of fidelity
Resolve complex problems pertaining to the design, development, analysis, integration, evaluation, testing, and verification of control systems and 6-DoF models and simulations.
Conduct verification and validation of launch vehicle and/or spacecraft.
Develop, modify, maintain, and improve software simulations, tools, and scripts.
Configure, conduct, and analyze 6-DoF Monte Carlo simulations.
Conduct trades studies and/or sensitivity analyses related to launch vehicles and spacecraft.
Create, edit, and debug software written in MATLAB, Simulink, and C/C++.
Prepare and present technical reports and/or briefings including visualization of results.
Create and review engineering and software documentation.
Qualifications
A degree in Aerospace, Mechanical or Electrical Engineering or related field from an ABET accredited institution is required. Typical experience requirements are the equivalent of a PhD with at least 4 years of experience, a master’s with at least 8 years of experience, or BS with at least 10 years of experience.
Required skills/experience:
Design and development of flight control systems (PID, state space, etc.) and actuator allocation (manual jet selection, quadratic programming, pseudo inverse, etc.) including TVC and/or RCS/Phase plane.
Analyzing system performance in the time and frequency domain (Nichols, Bode, Nyquist, Root Locus, etc.) using parametric, Monte Carlo, and statistical techniques.
Proficiency modeling, simulating, and analyzing the performance of launch vehicles, spacecraft, and landers.
Modeling of one or more spacecraft components/subsystems including Thrust Vector Control (TVC) actuators, Reaction Control System (RCS) thrusters, slosh, pogo, rigid and/or flexible body dynamics, and/or sensors.
Ability to derive multi-body spacecraft dynamics equations of motion, including both nonlinear equations and linear state equations and integrate subsystem models into larger simulations.
Programming in MATLAB, Simulink, and C/C++.
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.
Desired skills/experience:
Experience in performing software development, verification, and validation.
Programming in other languages such as Python.
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.
