Sim

Sim is building a platform to create autonomous AI agents for enterprise systems. The agent harness is the core system that ingests and reasons over a knowledge graph of company context to build and operate these agents. You will own the systems responsible for context retrieval, planning and execution, tool use, memory, and failure recovery. Your work will involve building evaluations and using production traces to enhance how company knowledge is translated into reliable agent behavior, directly shaping the harness architecture and future capabilities.
