Senior Full-Stack Developer (Python/React) Long-Term Opportunity Must Be Proficient with Claude

We're building a browser-automation platform that streamlines order routing and portal workflows for e-commerce retailers. The system includes a Python/FastAPI backend, a Chrome extension (React + TypeScript, Manifest V3), and a Next.js admin dashboard. The product is live and actively evolving, and we're looking for a senior developer to join us and take real ownership of features end to end. This is a long-term opportunity for the right candidate. We're not looking for a one-off gig worker — we want someone who will grow with the project, understand the product deeply, and become a core part of the team. What you'll work on: Backend features in Python/FastAPI (REST APIs, SQLAlchemy, background workers, integrations like FTP polling and email/OTP handling) Chrome extension development in TypeScript/React (content scripts, service workers, DOM automation) The admin dashboard in Next.js / React / Tailwind Debugging real-world automation issues across third-party websites
