Founding Engineer, Agents

About the Role

Build autonomous AI agents designed to perform complex computer-based work reliably over extended periods. You will own core agent systems, from execution and memory to evaluation, helping advance agents from human-reviewed runs toward dependable autonomous operation.

What You'll Do

• Build agents that can work toward a goal over multiple weeks with minimal or no human intervention.
• Design memory systems that help agents retain knowledge and improve as they work.
• Develop evaluation frameworks to determine whether agents outperform human task baselines.
• Improve agent reliability and reduce the need for human review of each run.

What We're Looking For

• Hands-on experience building production agents that people rely on, with a clear understanding of their failure modes.
• Experience building agent memory, long-running execution, or multi-step reasoning systems that maintain goals over time.
• Experience creating evaluation frameworks that inform real decisions and measure performance against human-level baselines.
• At least 1 to 2 years of experience at a fast-growing or AI-focused startup.
• A record of either publishing research that others build on or shipping software at meaningful scale.
• Strong engineering fundamentals; experience designing agent architectures is a plus.
• Background in competitive math, programming, debate, games, founding, or an equivalent high-achievement path is valued.
• Collaborative approach and conviction in the potential of AI agents.
