Sr FullStack (Node.js 80%, React 20%) $$$$

Senior Full-Stack Engineer with a strong backend focus to work on a large-scale web platform used by a significant number of customers. The system includes a site-building tool enhanced with AI features, a client-facing dashboard, and internal tooling for support operations.

About the role

The majority of your work will be focused on backend development using Node.js and TypeScript. From time to time, you’ll also contribute to frontend tasks built with React, though this represents a smaller portion of the workload.

Infrastructure and production environments are handled by a dedicated DevOps team. While you might occasionally experiment locally or in isolated environments, you won’t be responsible for managing production systems.

AI functionality is already integrated into the product via third-party services. You’ll be working with external APIs rather than building machine learning models from scratch.
