  • End-to-end features using React/Next.js, Python, and SQL.

  • Design intuitive interfaces for how users should delegate and override AI actions.

  • iMessage, communications channels, desktop-native, wearables integrations

Requirements

  • Strong foundation in React/Next.js and TypeScript.

  • Experience building and shipping complex web apps and/or browser extensions.

  • Familiarity with design systems like Figma

  • Preferred: Proof of meaningful open-source contribution.

  • Preferred: Strong UI/UX or design portfolio.

  • Sample Projects

  • Reusable tool call and output components for LLM-generated responses.
