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. COMPENSATION & BENEFITS $200,000 to $300,000 annual base salary, with up to $350,000 for exceptional candidates. Meaningful founding equity is offered. Visa sponsorship is available.
