About the Role
Join a small AI developer tooling team building a product that helps developers evaluate AI agents by working with execution traces. This hands-on role combines product engineering with community engagement, bringing feedback from agent builders directly into product decisions.
What You'll Do
-
Build and ship features for agent evaluation, replay, cohorts, and developer experience.
-
Share technical work through posts, demos, and discussions on X and GitHub, and use community feedback to inform product priorities.
-
Work across feature development, customer demos, marketing activities, and community engagement as needed.
-
Stay connected to AI agent builders and evaluation practitioners, including people working with LangGraph, Claude Code, and custom runtimes.
-
Use insights from community conversations, demos, and issues to improve the product, then share what you learn from shipped work.
What We're Looking For
-
At least 3 years of experience building or shipping production software, including experience building or evaluating agents in production.
-
Strong Python skills and hands-on experience with agent frameworks, evaluation systems, traces, observability, or agent debugging.
-
Open-source contributions with evidence of adoption by other developers, plus experience building developer tools, SDKs, APIs, libraries, or CLI tools.
-
Good product design and developer experience instincts, including attention to documentation, API ergonomics, and demos.
-
Experience supporting go-to-market activity for a product you engineered, such as technical demos or community engagement.
-
Comfort working in an early-stage startup or other high-uncertainty environment, taking on multiple responsibilities and participating in technical discussions on X or similar platforms.
