Our team is comprised of 10 companies working together on one mission Moon to Mars and then beyond

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 NASAs Space Launch System (SLS).

We are searching for highly qualified candidates to support the design development and oversight of the Human Lander Systems Program in the Control Systems Design and Analysis branch at NASAs 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!

Responsibilities include but are not limited to:

• Provide technical leadership guidance and mentoring to project/program team members

• Develop and/or oversee the development verification and validation of launch vehicle spacecraft and lander control systems.

• 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 conducting 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.

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 19 years of experience a masters with at least 23 years of experience or BS with at least 25 years of experience.

Required skills/experience:

• 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
