Full Job Description
The Role

As a Staff Software Engineer on the Agent Harnessing team, you will build the core architecture that allows AI agents to interact with and control complex, real-world physical systems. This spans agent orchestration, tool integration, low-latency communication layers, and execution environments-designed as a platform that Scout AI engineers can extend and depend on.

Responsibilities
  • Designing and advancing the agent harness (agent loop, tools, prompts, execution environment, capabilities) used across Scout AI's agentic stack.
  • Integrating fullstack software with physical hardware systems and AI agents-ensuring robust, low-latency communication across complex pipelines.
  • Building simulation environments and video-game-like frameworks that allow agents to be tested and trained before physical deployment.
  • Owning the connectors between AI models and real-world systems-the layer that translates model output into physical action.
  • Fine-tune frontier AI models and build the data acquisition pipelines that feed the training infrastructure powering our agents.
  • Work shoulder-to-shoulder with warfighters to turn capability requests into production-ready agentic systems - fast.

Qualification
  • 10+ years of full-stack engineering experience (startup or high-ownership environment preferred)
  • You have built complex agentic products or infrastructure-agent loops, orchestration systems, tool-use frameworks. You have strong opinions on model and agent behavior.
  • You are a systems-oriented fullstack engineer with hands-on experience integrating software with physical hardware or low-level systems.
  • You have exposure to simulation environments, game engines (Unreal, Unity, Isaac Sim), or robotics middleware (ROS/ROS2).
  • You have strong SWE fundamentals-architecture, distributed systems, real-time pipelines-and love shipping production systems.
  • Must be a U.S. Person due to required access to U.S. export controlled information or facilities

Benefits
  • Competitive compensation package including base salary and bonus
  • Meaningful equity
  • Premium medical, dental, and vision plans with $0 paycheck contribution
  • Competitive PTO and company holiday calendar
  • Catered lunch daily and fully stocked kitchen
  • Unlimited AI tokens
  • EV charging
  • Relocation assistance (depending on role eligibility)
