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.
