Job description

Job Summary:
Scout AI is developing Fury, the first robotic foundation model for defense, aimed at enhancing U.S. forces' capabilities. As a Software Engineer on the Agent Harnessing team, you will design and build the architecture that enables AI agents to control complex physical systems, ensuring robust communication and integration with hardware.
Responsibilities:
โ€ข Designing and advancing the agent harness (agent loop, tools, prompts, execution environment, capabilities) used across Scout AI's agentic stack.
โ€ข Integrating fullstack software with physical hardware systems and AI agentsโ€”ensuring robust, low-latency communication across complex pipelines.
โ€ข Building simulation environments and video-game-like frameworks that allow agents to be tested and trained before physical deployment.
โ€ข Owning the connectors between AI models and real-world systemsโ€”the layer that translates model output into physical action.
โ€ข Fine-tune frontier AI models and build the data acquisition pipelines that feed the training infrastructure powering our agents.
โ€ข Work shoulder-to-shoulder with warfighters to turn capability requests into production-ready agentic systems โ€” fast.
Qualifications:
Required:
โ€ข 5+ years of full-stack engineering experience (startup or high-ownership environment preferred)
โ€ข You have built complex agentic products or infrastructureโ€”agent loops, orchestration systems, tool-use frameworks. You have strong opinions on model and agent behavior.
โ€ข You are a systems-oriented fullstack engineer with hands-on experience integrating software with physical hardware or low-level systems.
โ€ข You have exposure to simulation environments, game engines (Unreal, Unity, Isaac Sim), or robotics middleware (ROS/ROS2).
โ€ข You have strong SWE fundamentalsโ€”architecture, distributed systems, real-time pipelinesโ€”and love shipping production systems.
Company:
Scout AI develops artificial intelligence systems for defense robotics, focusing on enabling autonomous behavior across unmanned platforms. Founded in 2024, the company is headquartered in Sunnyvale, USA, with a team of 11-50 employees. The company is currently Early Stage.
