KBR employs approximately 37,000 people worldwide with customers in more than 85 countries and operations in over 28 countries. KBR is proud to work with its customers across the globe to provide technology, value-added services, and long-term operations and maintenance services to ensure consistent delivery with predictable results.

Trinzic is the future independent company to be created through the planned spin-off of KBR's Mission Technology Solutions business, expected in January 2027. Our people work at the frontier of what is possible, delivering solutions in challenging environments and advancing some of the world's highest-priority national security and space missions.

Backed by decades of mission success, deep expertise, and trusted partnerships, Trinzic will launch as a global organization with more than 18,000 employees supporting customers around the world. Join us at a defining moment and help shape the future of a company built to tackle complex challenges and make a meaningful impact.

Candidates who join KBR's Mission Technology Solutions business before the spin-off will transition to Trinzic when the separation is complete and will not need to reapply for employment.

Key Responsibilities:

KBR is seeking a highly skilled and experienced Principal Modeling & Simulation Software Engineer to join a dynamic, high-performing, multidisciplinary team of military domain SMEs, modelers, and analysts located in Northern Virginia.

The ideal candidate shall:

Design, develop, and maintain modeling primitives, behaviors, and reusable software components using AFSIM scripting languages, C#, Razor, and other applicable technologies.
Implement new model capabilities and enhancements that accurately represent operational systems, platforms, sensors, weapons, command-and-control functions, and other mission-relevant entities.
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.

Strong collaborative skills with experience working in expert-driven, multidisciplinary teams

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
