CACI is looking for Space Vehicle Simulation Software Engineers and Math Model Developers to support development of Commercial Crew Program (CCP), Commercial Orbit Transfer System (COTS), Orion Spacecraft, International Space Station (ISS), and future vehicles simulations at the NASA / Johnson Space Center (JSC). The spacecraft simulations include high-fidelity math models used for crew training and engineering analysis in multiple NASA simulators and facilities, e.g., NASA Exploration Systems Simulations (NExSyS), Exploration Augmentation Module (EAM), Neutral Buoyancy Lab (NBL), and the Dynamics Skills Trainer (DST).

Duties and Responsibilities:

This work involves space vehicle systems simulation, math model development, and integration on Linux PC platforms using the Trickï-½ Simulation Environment Toolkit. Individual will develop large scale, high-fidelity simulation math models for NASA space vehicles. Space Vehicle Simulation Software Engineers and Math Model Developer duties and responsibilities include: Simulation math model requirements, architecture definition, and design. Simulation math model development. Debug, test, and verification work with simulation math models and simulation facilities. Space vehicle subsystem simulation model development and integration. Space vehicle functional and flight software integration. Simulation and crew training facility integration and testing. This work takes place in a highly stimulating and dynamic environment that is critical in the human space exploration initiative. This position requires a self-motivated, capable person wanting to work in a very team-oriented, friendly, but demanding environment. The ideal individual should have strong verbal and written communication skills, and strong customer relationship skills. Above all, the individual will have a positive, can-do attitude, be flexible, and be willing to take on new assignments and responsibilities as they arise. The ideal candidate has spacecraft domain experience in one or more of the following areas: Robotics, Environmental Controls and Life Support Subsystems (ECLSS), Electrical Power (EP), Thermal, Guidance, Navigation, and Control (GN&C), Environment (Earth, space, and planetary), Orbital Dynamics, Multi-body Dynamics, Contact Modeling, High Level Architecture (HLA), 1553 bus protocol. Strong C and C++ development skills required. Background & Experience (including education, skills work activities)

Required Qualifications:
- Degreed engineer with strong spacecraft simulation expertise combined with superior software development skills in C and C++ programming, Unix/Linux OS, scripting languages, and spacecraft domain expertise.
- Current software simulation experience with real-time, human-in-the-loop, hardware-in-the-loop systems.
- Must be a U.S. Citizen.
- B.S. in Aerospace, Mechanical, Electrical Engineering, Software Engineering, Computer Science, or related degree.
- At least 5 years current experience with software development in C and C++ in the Unix/Linux OS.
- Simulation Developmentï-½ Spacecraft and simulation math model development, real-time human-in-the-loop, hardware-in-the-loop.
- Ability to manage multiple priorities with little supervision.
- Must be a highly responsible, team-oriented individual with strong communication skills and work ethic.

Desired Qualifications:
- Prefer candidate with experience in NASA environment and knowledge of human spaceflight vehicle systems including robotic arms.
- M.S. or Ph.D. in Software Engineering, Computer Science, Aerospace Engineering, Electrical Engineering, or a related discipline.
- Experience in Perl, shell scripts, and/or Python.
- Experience in multi-threaded programming.
- Experience in High Level Architecture (HLA) or distributed simulation. Experience in 1553 bus protocol. Spacecraft domain experience in: Robotics, Environmental Controls and Life Support Subsystems (ECLSS), Electrical Power (EP), Thermal, Guidance, Navigation, and Control (GN&C), Environment (Earth, space, and planetary), Orbital Dynamics, Multi-body Dynamics, Contact Modeling Experience in one or more aerospace disciplines is a plus, e.g.,, real-time/embedded software, dynamics and control, robotics, space vehicle systems including electrical power systems, environmental control and life support systems, and/or avionics systems.

The position requires the successful completion and maintaining a NASA background investigation.
