Founding AI Research Engineer: Agent Harness & Model Systems
NewPosted 6 days ago
Founding AI Research Engineer: Agent Harness & Model Systems
- 4+ years of professional ML or software engineering, with recent hands-on work on agentic systems that ran in production and that real users or systems depended on.
- AI harness experience — required. You have built or worked deep inside the harness that turns a model into a working agent: tool-calling loops, structured outputs, context management, state, retries, guardrails, human-review gates. You know from experience that a model is only as good as its behavior in-harness, and you evaluate accordingly.
