## Description

We're looking for Software Engineers to help build and scale Weave. In this foundational role on a small but growing team, you'll design and ship core functionality, gather feedback directly from users and customers, and continuously improve the product experience. You'll work closely with cutting-edge AI builders, developing the next generation of tools that help teams understand, evaluate, and iterate on their AI agents.

 * Implement robust and ergonomic APIs.
 * Design and build integrations with popular agent harnesses and SDKs such as Claude Code, Codex, pi.dev, OpenAI Agents SDK, etc.
 * Scale and improve backend performance to support low-latency, high-volume production use cases.
 * Build polished and intuitive features such online LLM judges, playgrounds, evaluations, labeling, and tracing UX.
 * Partner directly with users to understand workflows, gather feedback, and rapidly iterate on solutions.
