Mission Modeling and Simulation Software Engineer, Senior

Booz Allen Hamilton•Washington, DC

About The Position

As a software engineer who builds in mission-driven domains, you’ve spent your career at the intersection of operational reality and software systems. You translate concepts, tactics, and effects into the models that make a platform credible. You know the difference between a system that works in the abstract and one that holds up when a planner runs it against a real scenario. We are building a decision-support platform for national security operations, and we need someone like you to build the mission layer that brings it to life. On this team, you’ll own the scenario execution layer and operational domain models for a platform that generates optimized courses of action under uncertainty. You’ll define action spaces, effects models, and constraint templates that give the solver something meaningful to reason over. Then, you’ll build the execution harness and vignettes that demonstrate cross-domain composition in operationally-relevant contexts. Your work is what makes this platform credible to the planners and evaluators who will put it to the test. You’ll join a small, elite team where everyone operates at the technical frontier. You’ll be the person who ensures the platform works against scenarios that defense planners and operators recognize as real, relevant, and challenging. You’ll build in a rapid development environment with AI-native tooling, delivering operationally relevant systems at engineering velocity. Join us. The world can’t wait.

Requirements

5+ years of experience developing software for modeling, simulation, or mission planning applications in defense, intelligence, or national security contexts
Experience building domain models that represent operational scenarios, including entity definitions, action spaces, effect chains, and constraint structures
Experience with effects modeling, including the representation of cyber operations, electronic warfare, or information activities within simulation or planning frameworks
Ability to translate operational concepts and doctrine into software-representable structures such as effect catalogs, constraint templates, or scenario specifications
Ability to obtain a TS/SCI clearance with a polygraph
Bachelor’s degree in a CS, Systems Engineering, or Operations Research field

Nice To Haves

Experience building effects catalogs or target-effects pairing systems that link actions to expected outcomes across multiple domains
Experience with simulation frameworks, wargaming platforms, or digital twin environments that have been demonstrated or evaluated in government exercise or test environments
Experience integrating physics-based or surrogate models into scenario execution workflows
Experience performing research in operations research, wargaming, effects-based operations, or modeling and simulation in an academic environment
Master’s degree in Operations Research, Systems Engineering, Modeling and Simulation, or a related field
