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.
