About the role
- You can reason about how agents retrieve and use company context, including knowledge graphs, tool calls, memory, and context management, and translate that understanding into reliable systems.
- We care about what you can do; projects, internships, and independent work count.
- If there appears to be a fit, we'll reach out to schedule 1-2 short technicals.
Responsibilities
- Teams connect their integrations and Sim builds a knowledge graph of company data and processes; from there, they work with Sim to build and monitor the AI agents and workflows that run production systems.
- you'll work directly with the founders and own your work from idea to execution.
- It's the agent that ingests and reasons over a knowledge graph of company context to build and operate agents.
- You'll own the systems that make this possible: context retrieval, planning and execution, tool use, memory, and recovery from failure.
- You'll build evals and use production traces to improve how the harness translates company knowledge into reliable agent behavior.
- Those findings will shape the harness architecture and the capabilities we build next.
