Qualifications: •SDK/library builder. You design clean, intuitive, hard-to-misuse APIs and think about the developer on the other side of your interface. •AI-first engineer. You've set up custom automation workflows (e.g., wiring Claude or similar LLMs into forms, APIs, or internal tools to replace manual work). •A self-starter who can take ownership of a project and work independently and collaboratively. •Rigorous about reviewing AI-generated output and taking full ownership of the code you ship. •Good attention to detail and initiative. •Strong written and verbal communication skills — including the ability to document an SDK so another engineer can succeed with it. •Proven experience designing and shipping a developer-facing SDK, library, or public API consumed by other engineers — including the public API/interface design, semantic versioning, and backwards-compatibility discipline that come with it. •Strong separation-of-concerns judgment — able to design framework-agnostic core logic (data, state, domain types) cleanly decoupled from thin, framework-specific bindings, so the same core can support multiple front-end frameworks over time. •2–3 years of professional experience with React & TypeScript, including building reusable, composable components and using strong types as a public contract. •Well-versed in building custom AI automation workflows (LLM API integrations, agentic tooling, or similar).
