Job summary

Anduril Industries seeks a full‑stack software engineer to build agentic modeling and simulation systems for operational planning. You will work at the intersection of applied AI, back-end services, model and simulation, and mission software to enable scenario authoring, entity tasking, and real-time analysis.

You will collaborate with warfighters and SMEs to translate planning workflows into reliable software, improving planning cycles from days to minutes and integrating DoD tools and concepts

Qualifications

• Strong production software engineer experience building backend services around complex stateful systems.
• Hands-on AI/LLM-powered software experience including tool calling, RAG, or agent orchestration.
• Ability to work with operators and SMEs to turn needs into concrete requirements.
• Willingness to obtain and maintain U.S. Top Secret clearance.

Responsibilities

• Build agentic workflows that make modeling and simulation capabilities accessible through natural language, structured tools, APIs, and operator-facing product experiences.
• Design multi-agent architectures that model human decision-making, adversary responses, operational constraints, and plan tradeoffs across complex military operations.
• Integrate LLM tool use, function calling, retrieval, planning loops, evaluation hooks, and guardrails with simulation engines, physics/modeling backends, and mission planning systems.
• Build backend services and interfaces for scenario creation, entity tasking, simulation state retrieval, course-of-action generation, plan comparison, and real-time analysis.
• Partner with warfighters, model/sim experts, autonomy engineers, game/simulation engineers, and mission software teams to translate ambiguous planning workflows into reliable software.
• Improve observability, reproducibility, and evaluation for agent behavior so generated scenarios and recommendations are inspectable, explainable, and operationally useful.
