Miami, Florida – Fully Onsite (Paid Relocation)

Are you Full-Stack with hands-on experience building AI-powered applications, strong React + TypeScript, Next.js, and Python or Node skills, and deep experience with SQL/Postgres or Supabase?

Have you built multi-tenant, data-driven platforms with real-time UIs, dashboards, or interactive workflows? If you’re ready to own systems end-to-end in a true 0-1 environment, this perfect for you!

Join a well-funded, AI-native startup at a critical growth stage, already powering millions of real-world interactions per month across higher education, insurance, and travel clients. You’ll ship production-grade AI systems, not prototypes, that deliver real commercial impact.

You’ll be one of the engineers shaping how full-stack AI systems are architected, deployed, and scaled. You’ll own everything from React frontends and Next.js APIs to Supabase/Postgres backends, integrating AI agents and LLMs (Claude API, OpenAI API, Groq) into production workflows with a focus on performance, security, and scalability.

If you’ve already built AI-driven product features and want to architect, scale, and deploy real-world AI platforms, this is a standout opportunity to make a technical impact in a high-growth, well-funded startup.
