Early Career NASA Spacecraft GNC Modeling and Simulation EngineerJob Category: EngineeringTime Type: Full timeMinimum Clearance Required to Start: NACIEmployee Type: RegularPercentage of Travel Required: Up to 10%Type of Travel: Continental USCACI is looking for Early Career Spacecraft Guidance, Navigation, and Control (GNC) Modeling and Simulation Engineers 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 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. The individual will develop high-fidelity simulations and 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 (GNC); Environment Modeling (aerodynamics, solar pressure, and thermal); Orbital Dynamics.What You’ll Get to Do: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.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.More About the Role: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.Job responsibilities include:
Design and development of 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.
Presentation of analysis results and their impact on spacecraft performance, vehicle design and mission design to customers.
You’ll Bring These Qualifications:
U.S. Citizen or Permanent Resident for access to USG Facilities.
B.S. in Aerospace or Computer Engineering, Computer Science, or related disciplines
Minimum of 1-3 years’ relevant work in aerospace software development projects including school project work or internship experience in the areas below.
Orbital mechanics, particularly rendezvous and proximity operations.
Software development, including overall project design, programming, testing, verification, and documentation.
Strong computer and software development skills using C/C and Python. Preferred in both Linux and Windows environments.
Software version control tools such as git.
Ability to manage multiple priorities with minimal supervision.
Highly responsible, team-oriented individual with strong work ethic.
Highly developed coordination and organization skills.
These Qualifications Would be Nice to Have:
M.S. Aerospace or Computer Engineering, Computer Science or Modeling and Simulation. Prefer coursework and thesis topic in relevant technical area.
Experience with software simulation programming and scenario development, e.g., CACI/NASA Trick simulation is a plus.
Experience with using NASA VERAS to generate analysis reports.
Experience with spacecraft simulation development using NASA JEOD.
Experience with using EDGE/DOUG for simulation visualization.What We Can Offer You:
