Your Role
- Designing, building, and shipping developer-facing SDKs consumed by other engineers.
- Owning the SDK as a product: the public API surface, TypeScript types, semantic versioning, packaging/distribution, backwards compatibility, and documentation.
- Building and maintaining AI-powered automation workflows that connect our product to internal and external systems.
- Developing and testing new features using AI-assisted tooling and autonomous agents, maintaining the codebase, integrating with APIs and data models, and owning the PR lifecycle (writing, reviewing, and incorporating feedback).
- Collaborating across web, mobile, and backend teams to align on best practices, shared architecture, and product direction.
- Partnering with Product and Design to translate designs and prototypes into shipped solutions for our users and the engineers who build on our SDK.
About You
- 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.
