Job summary

NextGen Federal Systems seeks an experienced AFSIM Scenario Developer to support N&NC mission areas through advanced modeling, simulation, analysis, and scenario development. Build high‑fidelity operational scenarios for planning, experimentation, and wargaming activities.

The role requires 5+ years in aerospace/defense with AFSIM, and an active TS/SCI clearance; you will create space, air, land, and maritime models, implement BAM techniques, run Monte Carlo simulations, and document

Qualifications

• BS or equivalent in Computer Science, Engineering, Mathematics, or equivalent technical degree.
• 5+ years’ prior work experience in the aerospace or defense industry, with demonstrated AFSIM experience.
• Must have an active Top-Secret SCI (TS/SCI) security clearance.
• Demonstrated proficiency and experience in the AFSIM development environment.
• Strong understanding of military operations across space, air, land, and maritime domains.
• Experience developing behavior models, agent-based simulations, or Monte Carlo analytical methods.
• Ability to translate government specifications into fully functional AFSIM scenarios and platform models.
• Experience documenting technical interfaces and providing user instructions.
• Ability to produce clear, professional reports and briefing materials.

Responsibilities

• Build scenarios in the AFSIM software environment that accurately represent N&NC interests and mission areas.
• Support development of CONPLAN materials, Table-Top Exercises (TTX), wargames, and select experimentation projects using AFSIM-based modeling and simulation (M&S) products.
• Align all scenarios with core mission areas, including representations of Golden Dome and Border missions.
• Develop realistic representations of space, air, land, and sea platforms, including sensors, communication links, and behavior models.
• Implement Behavior and Agent Modeling (BAM) techniques and utilize Monte Carlo methods for scenario execution.
• Save scenarios, platforms, and related objects in a data repository to ensure standardization and future reuse.
• Develop interfaces for import/export between AFSIM and other software entities
• Document interface designs and produce user instructions.
• Run AFSIM simulations in support of N&NC analysis tasks and overall M&S efforts.
• Build and execute AFSIM scenarios for CONPLAN development, TTXs, wargames, and experimentation projects as tasked.
• Prepare and deliver data outputs, written reports, and briefing products as required by the Government.
