Develop model compositions and complex behaviors by integrating lower-level primitives into reusable simulation constructs.
Create and execute verification and validation test plans to ensure model functionality, performance, and fidelity prior to integration into the core simulation framework.
Identify, troubleshoot, and resolve software defects and model performance issues through structured testing and debugging.
Prepare technical documentation describing model design, implementation approaches, assumptions, limitations, and test results.
Collaborate closely with software engineers, integration teams, analysts, and subject matter experts to ensure models meet mission and technical requirements.
Support integration, regression testing, and configuration management activities associated with deployment into enterprise modeling and simulation environments.
Provide technical guidance and peer reviews to promote software quality, consistency, and adherence to development standards.

Desired:

Master of Science in Computer Science, Software Engineering, or other STEM field with 12+ years of relevant experience
Experience developing or modifying Razor-based model components
Experience developing reusable software libraries, model primitives, behaviors, or simulation extensions for integration into larger modeling and simulation frameworks
Familiarity with MBSE techniques and tools, with the ability to translate operational concepts and behavioral models into executable simulation capabilities
Familiarity with automated testing, continuous integration, or software quality assurance processes within modeling and simulation environments
Experience with source control, software configuration management, automated build pipelines, and CI/CD tools such as Git, GitLab, Jenkins, DevOps, or similar platforms
Experience representing military systems, sensors, weapons, effects, or command-and-control processes in mission-level simulations
Scheduled Weekly Hours:40hrs
