The Opportunity:

CACI is looking for an experienced Spacecraft Guidance, Navigation, and Control (GNC) Modeling and Simulation Engineer to work with NASA's human-rated spacecraft systems in support of our Nation’s space exploration initiative at NASA / Johnson Space Center in Houston, TX. Candidates should have great interest in spacecraft vehicles and systems, enjoy working with software, and most of all, possess a great passion to contribute to our Nation’s exploration of space.

This position involves engineering, modeling, and simulation support as part of our space vehicle GNC modeling and simulation engineering team. The individual will develop high-fidelity simulations and math models for NASA space vehicles and will utilize those models for engineering analysis with a focus on spacecraft GNC. This includes integration, verification, and validation for simulations and math models on Linux PC platforms using the Trick© Simulation Environment and Development Toolkit developed by CACI. The ideal candidate has experience and an educational background with spacecraft domain expertise in the following areas: Guidance, Navigation, and Control (GNC); Environment Modeling (aerodynamics, solar pressure, and thermal); Orbital Dynamics. 

The engineer in this role 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. Tasks can include but are not limited to developing standalone and integrated simulations, GNC models, and avionics models, executing engineering analysis, and evaluating analysis results.

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:

• Design and develop math models for spacecraft systems and subsystems including hardware and software.
• Develop simulation scenarios to certify spacecraft ascent abort systems. Develop and maintain CI/CD pipelines to ensure the reliability of the CI/CD processes.
• 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 or Computer Engineering, Computer Science, or related disciplines with experience in software development, including overall project design, programming, testing, verification, and documentation.
• The greater the experience the better. Strong computer and software development skills using C/C++ and Python.
• Experience with software version control tools such as git.
• Experience in Linux and Windows environments.
• Ability to manage multiple priorities with minimal supervision.
• Highly responsible, team-oriented individual with strong work ethic.

Desired: 

• M.S. Aerospace or Computer Engineering, Computer Science or Modeling and Simulation and relevant work experience in aerospace software development projects.
• Experience with software simulation programming and scenario development, e.g., CACI/NASA Trick simulation is a plus.
• Experience with spacecraft simulation development using NASA JEOD. Experience with 6-DOF modeling of complex dynamic systems.
• Experience using SLURM to execute batch job submissions.
• Familiarity with atmospheric modeling, e.g. GRAM.
• Experience with MATLAB/Simulink, particularly with auto code generation
