About the Job

Requirements

  • Bachelor's degree and a minimum of 6 years of prior relevant experience, or a graduate degree and a minimum of 4 years of prior related experience; in lieu of a degree, a minimum of 10 years of prior related experience.
  • Active Department of Defense Top Secret security clearance.
  • Professional experience executing simulation in MS&A analytic tools and frameworks such as AFSIM or STK.
  • At least 2 years of experience integrating systems simulations with Model-Based Systems Engineering tools such as Cameo, ModelCenter, DOORS, or Rhapsody.
  • At least 2 years of experience with scripting languages such as Python, C++, C#, R, or MATLAB, including Anaconda with Python.
  • Professional experience working with Agile development methodology, version control, and Atlassian tools such as JIRA, Confluence, Git, or TortoiseGit.
  • Prior U.S. military, Department of Defense, or other U.S. Government engineering or operations experience.
  • Ability to obtain TS/SCI/SAP clearance.

Responsibilities

  • Coordinate MS&A engineering efforts to integrate system performance and behaviors into operational analysis.
  • Design multi-domain simulation capabilities in AFSIM, MATLAB, and/or STK in support of MAG Technology and Mission Roadmaps, Internal Research and Development efforts, and Programs of Record.
  • Integrate Government-off-the-Shelf and Customer-off-the-Shelf simulations, frameworks, models, and analytic toolsets into existing software infrastructure such as AFSIM, MATLAB, and/or STK.
  • Build and maintain analytic toolsets representing each phase of the find, fix, target, track, engage, and assess chain using sensor, effects, and communications technologies, including decision-support aids such as data visualization and Unity game engines, to support operations assessment; develop and refine lessons learned.
  • Document model specifications to establish a reusable repository of simulation capabilities, frameworks, algorithms, system models, and analytic toolsets at multiple classification levels, while maintaining configuration-management protocols.
  • Support programs and pursuits by creating models, simulations, and analysis products; determine requirements, develop simulation software, troubleshoot existing simulation capabilities, and create software designs and test plans.
  • Support requirements development, system verification, and concept-of-operations development; work with Technical Leaders and subject-matter experts to ensure modeling, simulation, and analysis capabilities meet operational mission requirements.
  • Develop new simulation capabilities and employment processes, and enhance current analytic toolsets.
  • Support internal and external technical expos and roadshows by sharing knowledge of signature simulation capabilities and products.
  • Communicate with internal and external parties, including customers and vendors, to influence acceptance of individual or team views, practices, concepts, and approaches; communicate matters of importance to function or business-area leadership and conduct briefings with senior leaders as needed.
  • Make improvements to processes, systems, or products and establish short-term operational plans with measurable contributions to function or business-area results.
  • Perform additional duties and responsibilities as assigned.

Desired Qualifications

  • Active TS/SCI clearance.
  • Professional experience relevant to operations analysis, mission engineering, operational planning, mission integration, or capability development within the U.S. military, Department of Defense, or another U.S. Government agency.
  • Advanced experience supporting multi-domain modeling, simulation, and analysis problems and using system-through-mission-level modeling and simulation tools and frameworks.
  • Prior experience with one or more of the following: aerodynamic systems, orbital mechanics, signal processing, sensor systems, and radio-frequency or electro-optical/infrared physics.
  • Highly effective organization-level communication, presentation, interpersonal, data-visualization, and storytelling skills.
  • Advanced experience with Government or industry MS&A analytic tools and frameworks such as AFSIM, PIANO, STK/Astrogator, MATLAB with Simulink, Python, or Java.
  • Advanced experience with Model-Based Systems Engineering tools such as Cameo, ModelCenter, DOORS, or Rhapsody.
