CWMD Computer Programming SME

Sayres is seeking candidates for a CWMD Computer Programming SME supporting Headquarters Air Force (HAF). This position is located in the NCR.

Summary

Sayres is seeking a highly skilled Software Programmer with experience in Python, C++, and Visual Basic to serve as the primary CWMD modeler-and Nuclear Effects modeler when required-for advanced modeling and simulation efforts. The selected candidate will design, develop, and refine computational models that characterize chemical, biological, radiological, and nuclear (CBRN) agent behaviors, their operational impacts, and their integration into complex air operations environments.

Roles/Responsibilities:

• Serve as the lead modeler for CWMD and nuclear effects, developing and maintaining models that simulate chemical, biological, radiological, and nuclear agent effects, attributes, and behaviors across diverse operational scenarios.
• Build and refine models that incorporate environmental variables (e.g., weather patterns, temperature, humidity, terrain, atmospheric stability) and assess their influence on agent dispersion, persistence, degradation, and operational risk.
• Incorporate scientific datasets, test results, intelligence inputs, and operational parameters into modeling frameworks to ensure accuracy, realism, and defensibility.
• Translate complex scientific and operational data into computational logic, algorithms, and simulation modules.
• Develop, test, and optimize software tools, scripts, and modeling applications using Python, C++, and Visual Basic.
• Implement modular, scalable code that supports iterative model refinement and integration with existing DoD modeling and simulation environments.
• Collaborate with system engineers, analysts, and operators to ensure models interface correctly with broader mission planning, decision support, and operational assessment tools.
• Work directly with government customers to refine modeling requirements, interpret results, and support briefings or technical discussions.
• Produce clear, defensible documentation including model descriptions, assumptions, limitations, validation summaries, and user guides.
• Support rapid turn modeling requests and emerging operational needs.

Required Skills and Education:

• Bachelor's degree and 5+ years of relevant experience OR Associate's degree and 8+ years of experience OR High School diploma and 11+ years of experience.
• Demonstrated experience in software development, including:
  
  
  
  • Programming in Python, C++, and/or Visual Basic
  • Developing algorithms, simulations, or analytical tools
  • Debugging, testing, and optimizing code for performance and accuracy
  
  
  
  
• Foundational understanding of:
  
  
  
  • Network development and operations
  • Communications and control systems
  • Systems engineering principles
  
  
  
  
• Knowledge of aircraft and satellite communications systems, including:
  
  
  
  • System architecture and integration
  • Cybersecurity considerations for mission systems
  
  
  
  

Security Clearance:

• Top Secret with SCI eligibility
