Location: United States
Workplace: Onsite
Employment Type: Full time
Job Function: Software Engineering
Seniority: Mid level

Key Responsibilities

  • •Build agentic workflows that make modeling and simulation accessible via natural language, structured tools, APIs, and operator-facing experiences.
  • •Design multi-agent architectures to model human decision-making, adversary responses, operational constraints, and plan tradeoffs across complex operations.
  • •Integrate LLM tool use, function calling, retrieval, planning loops, evaluation hooks, and guardrails with simulation engines and mission planning systems.
  • •Develop backend services and interfaces for scenario creation, entity tasking, simulation state retrieval, course-of-action generation, and real-time analysis.
  • •Improve observability, reproducibility, and evaluation so agent-generated scenarios and recommendations are inspectable and explainable.

Pay and Benefits

Salary: USD 191,000 - 292,000 annually

Key Requirements

  • •Strong production software engineering experience building backend services, APIs, platforms, or integrations around complex stateful systems.
  • •Hands-on experience building AI/ML or LLM-powered software, ideally including tool/function calling, RAG, structured outputs, agent orchestration, or model evaluation.
  • •Proficiency in Python, Go, or a similar backend language, with ability to work across service boundaries and integrate with external systems.
  • •A degree in Computer Science, Software Engineering, Mathematics, Physics, or a related technical field.
  • •Eligible to obtain and maintain an active U.S. Top Secret security clearance.
