Summary

We’re looking for an experienced AI Automation & Full-Stack Developer to help build and continuously improve an AI-powered customer engagement and operations platform.

The developer will work across the full stack and should be comfortable owning architecture as well as implementation. The core stack will include Python/FastAPI, React, PostgreSQL/Supabase, OpenAI or Claude, REST APIs/webhooks, and AWS or GCP.
