The Opportunity:
We are seeking a Modeling and Simulation (M&S) subject matter expert and small team leader to assist simulation development for the National Ground Intelligence Center (NGIC) through formulating, analyzing, executing, and delivering M&S studies to answer customer questions.

Most of these studies will be performed through AFSIM, while others could employ ITASE, ODESSA, Eco-System, or others.

You will take requests from external customers, join the government in the conversation while understanding what questions need to be asked to initially map and scope the project and chart a course towards answering the request. This will require breaking the given scenario into pieces by working backwards from the expected deliverable, map the project, and assign personnel around them to work different pieces in parallel, often taking on the toughest and most complex components themselves.

Documentation of this process is critical and should identify steps, assumptions, limitations, knowns, gaps, and issues. 

You will be required to understand the kinds of models and systems NGIC addresses and collaborate with intelligence SMEs to understand the data and how it needs to be analyzed and presented to the customer.


Responsibilities:

  • Solid foundation and proficiency in the scientific method and developing a research plan that starts with an ill-defined question and ends with a published report that will stand up to peer review.
  • Conduct experiments to understand the behavior of the system (or SoS) and/or evaluate various strategies for the operation of the system.         
  • Technical proficiency with appropriate M&S models (especially AFSIM), tools, and environments to provide an active role in the carrying out of simulations.  
  • Use experimentation and testing as a strategic advantage—cutting test durations, revealing critical insights early and often, and turning raw data into insights 
  • Examine cause and effect and verify controllable inputs and accurate, repeatable measurement systems. 
  • Recognize how to format a problem or evaluation to take advantage of the DOE process and solution. Collaborate with the team to answer questions such as “What should we test and why?” or “How much testing is enough”.  Shorten testing durations of complex systems to enable analysts who need to understand key performance indicators (KPIs). 
  • Apply the scientific method to support analysis, including statistics and graphical analyses.
  • Write test plans and reports supported by scientific methods.
  • Examine cause and effect; verify controllable inputs and accurate, repeatable measurement systems

Qualifications:

  • Accredited degree in physics, engineering, computer science, applied math, or similar discipline with broad engineering and computer science knowledge. Master’s degree or Ph.D. is highly preferred.
  • 10+ years of experience serving in a M&S role on DoD related programs and projects. 
  • Experience with multiple M&S tool suites, with a very strong preference for AFSIM experience.
  • Must have strong interpersonal, verbal, and written skills.  
  • Active in scope DoD TS/SCI security clearance is a requirement
    Nothing lower than a TS clearance will be considered. 
  • Ability to conduct analysis and produce comprehensive technical assessments that include independent research and technical writing.  
  • U.S. Military experience is beneficial but not required.   
  • Experience working in or with the intelligence community is beneficial but not required.  
  • Must possess the ability to work independently with minimal oversight while maintaining focus on objectives defined by the client.
