SimSpace builds the AI Proving Grounds, a platform designed to help organizations validate, operationalize, and build AI agents that work alongside human operators inside realistic digital replicas of production environments. The company serves allied governments, militaries, enterprises, and research institutions worldwide by providing live-fire simulations that test agentic and human defenses against LLM threats, generate hyper-synthetic data, and evaluate agent trajectories including tool calls and error recovery.

The organization focuses on creating adaptive, AI-ready defenses that allow security teams to stress-test agentic solutions under real-world conditions. Founded in 2015 by experts from U.S. Cyber Command and MIT Lincoln Laboratory, SimSpace unifies training, testing, and validation into a single platform that helps evaluate security investments and compress cyber readiness cycles.

The current open roles indicate that SimSpace is building distributed technical and cybersecurity teams across international locations. The open positions include a Senior Threat Hunter and a Senior Software Engineer for the Cyber Range, and both listed roles are remote positions located in the U.K. and Costa Rica respectively.
