Founding Engineer, Agents

ABOUT THE ROLE Build autonomous agents designed to handle complex computer-based work reliably over extended periods. You will own core agent systems, from execution and memory to the evaluations that measure performance against human baselines. WHAT YOU'LL DO - Build agents that can pursue a goal over multiple weeks with minimal human intervention. - Design memory systems that help agents retain knowledge and improve over time. - Develop evaluation frameworks to determine whether agents outperform people on specific tasks. - Improve reliability and reduce the need for human review of agent runs. WHAT WE'RE LOOKING FOR - Hands-on experience building production agents that people rely on, including a clear understanding of their failure modes. - At least 1 to 2 years of experience at a fast-growing or AI-focused startup. - Experience building agent memory, long-running execution, multi-step reasoning, or systems that maintain goals over time. - A track record building evaluations that inform real decisions, including comparisons against human-level baselines. - Evidence of substantive engineering work, with either published research others build on or software shipped at meaningful scale. - Strong engineering fundamentals; a degree from a highly selective institution or an equivalent credential, such as founding a company, is valued. - Agent architecture experience and backgrounds in competitive math, programming, debate, or games are beneficial. - A collaborative, thoughtful approach to working through difficult problems. COMPENSATION & BENEFITS Base salary is $200,000 to $300,000 annually, with up to $350,000 for exceptional candidates. Meaningful founding equity is included. Visa sponsorship is available.
