About the role

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).

Responsibilities

• 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
• 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
• 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 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.

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
• 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
