Your work will be the primary touchpoint for our partners, making their success your own. This role is ideal for a web developer with strong backend skills who is passionate about building the bridges between a core protocol and its real-world applications.
Web SDK Development: You will own the design, development, and maintenance of our public-facing JavaScript/TypeScript SDK, ensuring it is designed for the future, robust, well-documented, and easy for partners to use.

You have a proven track record of building high-quality web applications and well designed developer APIs and SDK. You are fluent in the modern web stack and possess the backend proficiency to build and manage the services that power your applications. You are passionate about creating excellent developer experiences and understand that the success of an SDK is measured by the success of the developers who use it. You can communicate clearly, work effectively in a fast-paced environment, and are motivated by the challenge of building the user- and developer-facing layers of an ambitious, world-changing protocol. You are an effective and respected tech lead of small teams.
