Senior Dynamics and Controls Engineer (JR060226A-9)

JBS Solutions•Huntsville, AL

7d•Onsite

About The Position

JBS is seeking a highly qualified candidate to support the design, development, and oversight of the Human Lander Systems Program in the Control Systems Design and Analysis branch at NASA’s Marshall Space Flight Center as a Dynamics, Controls, Modeling, Simulation, and Analysis Subject Matter Expert. This exciting work will serve as a critical step in sending humans back to the Moon, Mars and beyond!

Requirements

A degree in Aerospace, Mechanical or Electrical Engineering or related field from an ABET accredited institution is required.
Proof of U.S. Citizenship is required.
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.
