The Opportunity:

This work involves math model and simulation development, integration, verification and validation on Linux PC platforms using the Trick9 Simulation Environment and Development Toolkit. Individual will develop math models and simulations in support of the Artemis program for NASA space vehicles with a focus on Orion. The ideal candidate has spacecraft domain experience in Guidance, Navigation, and Control and a simulation development background.

The engineer in this role will support Orion math model and simulation development and engineering analysis for Orion. The engineer will identify and implement improvements to math models and simulation scenarios, analyze simulation data to evaluate system characteristics and performance, and support continual enhancements to the simulation architecture.

This position requires a self-motivated, capable person with strong verbal and written communication skills. In addition to outstanding technical expertise, the individual must be very people savvy with strong customer relationship skills, possess a positive team-player attitude, and be flexible and willing to take on new assignments and responsibilities as they arise. Finally, the most qualified candidate will be an articulate speaker able to communicate complex technical ideas in a convincing manner, must share our passion for our Nation's Space Program, and share in the excitement of developing the next human-rated space vehicles.

Responsibilities:

  • Develop space vehicle system and subsystem simulation math models, verify model requirements, and validate the simulation and models.
  • Design and develop math models for spacecraft systems and subsystems including hardware and software.
  • Develop simulation scenarios to test nominal and off-nominal spacecraft operations.
  • Perform analysis on simulation data to investigate spacecraft system performance.
  • Present analysis results and their impact on spacecraft performance, vehicle design and mission design to customers.


Qualifications:
Required:

  • U.S. Citizen or Permanent Resident for access to USG Facilities.
  • B.S. in Aerospace Engineering or related disciplines with experience in software development, including overall project design, programming, testing, verification, validation, and documentation.
  • Experience working with aerospace vehicle simulations and math model development.
  • Experience with Trick simulations and math model verification and validation processes.
  • Experience with C++ and Python in a Linux environment.
  • Experience with software version control tools such as git.
  • Strong computer and software skills in Linux environments.
  • Ability to manage multiple priorities with minimal supervision.
  • Highly responsible, team-oriented individual with strong work ethic.


Desired:

  • M.S. Aerospace Engineering and relevant work experience in aerospace software development projects.
  • Experience with software simulation programming and scenario development, e.g., NASA / CACI Trick simulation is a plus.
  • Experience with NASAs VERAS Python tool suite is a plus.
  • Experience with spacecraft simulation development using NASA JEOD.
  • Experience with one or more spacecraft domain including orbital dynamics, robotic dynamics, Guidance, Navigation, and Controls, flexible body dynamics, vehicle kinematics, sensors, and effectors. Greater experience is highly valued.
  • Experience with Continuous Integration tools and methods.
  • Experience with Monte Carlo simulation methods.
  • Experience with MATLAB/Simulink.
