CACI is looking for a 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.

What You’ll Get to Do:

This work involves space vehicle GNC development and design, math model and simulation development and integration on Linux PC platforms using the Trick© Simulation Environment and Development Toolkit developed by CACI. Individual will develop high-fidelity simulation math models for NASA space vehicles. The ideal candidate has an educational background with spacecraft domain experience in the following areas: Guidance, Navigation, and Control (GN&C); Environment (Earth, space, and planetary); Orbital Dynamics.

The engineer in this role will identify and present opportunities derived from modeling activities, 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.

More About the Role:

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, strong customer relationship skills, possess a positive team-player attitude, 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.

  • Design and development of math models and simulation models for spacecraft systems and subsystems including GNC.

  • Development of real time simulation models.

  • Analysis of technical documentation.

  • Validation of the developed models.

  • Analysis and Documentation of the simulation results.

  • Presentation of conclusions and their assessed impact on spacecraft performance, vehicle and mission design to our customers.

  • Verification and test activities for GNC models.

This work takes place at NASA/JSC in Houston, TX, a highly stimulating and dynamic environment that is critical in human space flight and the space exploration initiative.

You’ll Bring These Qualifications:

  • Must be a U.S. Citizen or Permanent Resident.

  • B.S. in Aerospace or Mechanical Engineering, or related disciplines required.

  • A minimum of 6 months to 5 Years developing spacecraft simulation models.

  • Experience programming in C, C++, and Python.

  • Experience with Spacecraft GN&C.

  • Experience working in a Linux development environment.

  • Experience developing, verifying, and validating math models and integrated vehicle simulations.

  • Must be flexible, open to new challenges in a dynamic environment, and possess strong technical expertise combined with strong verbal and written communication skills.

  • Ability to manage multiple priorities with little supervision.

  • Must be a highly responsible, team-oriented individual with strong work ethic

These Qualifications Would be Nice to Have:

  • M.S. in Aerospace Engineering, or Graduate level coursework or research involving dynamics and controls, flight/orbital mechanics, GNC, space vehicle systems, or software simulation is a significant plus.

  • 10+ years of experience developing spacecraft simulation models. Greater experience is significantly valued.

  • Technical project leadership skills and experience.

  • Experience with the NASA / CACI Trick Simulation Environment is highly desirable, but not mandatory.

  • Experience delivering simulation software products and engineering analysis to support integrated spacecraft GNC design and verification.

  • Familiarity with Monte Carlo methods and analysis.

What We Can Offer You:

  • We’ve been named a Best Place to Work by the Washington Post.

  • Our employees value the flexibility at CACI that allows them to balance quality work and their personal lives.

  • We offer competitive benefits and learning and development opportunities.
