Senior Full-Stack Engineer for Ai-Powered SaaS Platform (next.js + Supabase)

We're building an AI-powered SaaS platform and need an experienced full-stack engineer to own features end to end. The stack is React / Next.js with TypeScript on the front end, Node.js on the back end and Supabase (Postgres, auth, role-based access) for data. You'll build new features, connect REST APIs and third-party integrations, and add AI features using the OpenAI API. We work with AI coding tools such as Claude Code and Cursor, so you should be comfortable using them while writing clean, maintainable code. Expect 1 to 3 months at under 30 hrs/week, with potential for ongoing work. To apply, please include examples of similar SaaS work and the tech stack you used.
