Founding Agentic Engineer

ABOUT THE ROLE Join an early-stage team building agentic software for real-world business systems. You will own the agent layer end to end, setting the patterns for how agents are built, evaluated, and improved in production. WHAT YOU'LL DO - Build context and self-learning systems that accumulate knowledge and improve agent performance over time. - Develop workflows that detect production failures, diagnose their causes, and recover autonomously. - Create and evolve the agent harness and meta-harness for building and evaluating agents efficiently. - Establish practices for agent tracing, evaluation, and iterative improvement across the product. - Work closely with the founders, experiment with new approaches, and help hire and grow the team. WHAT WE'RE LOOKING FOR - Two to nine years of professional software engineering experience, including experience building software at an early-stage company or as a startup founder. - Recent experience building agentic software and shipping working systems to production. - Strong experience with context engineering, eval-driven iteration, agent tracing, and production evaluation. - Hands-on experience building systems that learn from accumulated knowledge, autonomous failure detection or recovery workflows, or reusable agent harnesses. - Proficiency with TypeScript, Effect-TS, PostgreSQL, and LLM or agent technologies. - A completed or in-progress degree in engineering, computer science, or a quantitative field from a strong technical university.
