Job Description:

Leidos is seeking Mid-Level Software Engineers experienced with AFSIM or Modeling & Simulation. AFSIM is a U.S. Air Force simulation environment written in C++ and utilized for engagement-level and mission-level analysis by military operations research analysts to evaluate combat effectiveness of advanced weapon system concepts. AFSIM is a Monte Carlo simulation tool which may be run either constructively to generate analytic results, or in real-time to support Operator in the Loop (OITL) Experimentation and Wargaming needs. AFSIM is now becoming accepted as a standard operations analysis tool across DoD and industry.


  • Develop next generation AFSIM-based OITL simulation environment for analysts and warfighters.
  • Improve the AFSIM Integrated Development Environment (IDE), which provides a user interface to AFSIM for scenario generation, model execution, and results visualization.
  • Utilize visualization tools with Qt for GUI controls and Open GL and Open Scene Graph (OSG) for graphics.
  • Perform research in Artificial Intelligence (AI) techniques as applied to military tactics and human behavior representations.
  • Ongoing development of physics-based representations of aerospace vehicles, weapon systems, sensors (including tracking and fusion capabilities), Electronic Warfare (EW) techniques, cyber effects, and communication systems.
  • Develop C++ simulation software, including mathematical and physics based algorithms and graphical user interfaces and visualization.
  • Participate within a software development team to design, develop, test, and deploy assigned modeling and simulation software.
  • Apply software best practices (software development processes, version control, documentation, etc.) for all developed and modified software.
  • Interact with government and industry customers to define requirements and meet analytic needs.

 Required Qualifications:

  • U.S. Citizenship is required, as is an active Secret clearance.
  • Bachelor’s degree in engineering, mathematics, computer science, or related technical discipline and at least 2 years of related experience (We have multiple levels associated with this opportunity and will consider all levels.)
  •  Experience developing object-oriented software using programming languages such as C++, C#, or Java.

 Desired Qualifications:

  • Experience with the AFSIM software and tools.
  •  Experience working with LINUX environments.
  • Proficiency solving mathematical and physics-based problems of moderate complexity.
  • Experience with software version control tools (Git, Subversion, CVS, etc.).
  • Advanced skills developing C++ software with the Visual Studio integrated development environment.
  • Knowledge and experience with Modeling and Simulation (M&S) environments (constructive and virtual) and Modeling, Simulation, and Analysis (MS&A) concepts.
  • Domain knowledge in an engineering discipline relating to aerospace and defense (e.g., Aero, G&C, EE).
