Responsibilities

Develop a deep understanding of the simulation’s features, constraints, and emergent dynamics
Research military doctrine and commander intent to understand the expectations for how entities should behave under a broad range of circumstances
Conceptualize and design AI behavior models using HTNs, GOAP, state machines, and related decision frameworks that can express a wide range of intended outcomes and behaviors
Define the structure, abstractions, and constraints of the entity “brain,” in close collaboration with engineering
Translate high-level intent (doctrine, rules, roles, objectives) into concrete, inspectable, and configurable decision logic
Design and author entity behavior using a visual scripting editor
Design behavior systems that support variation, parameterization, and reuse, rather than hard-coded outcomes
