Job Description

We’re looking for a strong full-stack developer with deep experience in Node.js + TypeScript to own the end-to-end delivery of complex applications. You will move beyond standard CLI builds to architect self-hosted applications and robust backend services that integrate seamlessly with the Wix ecosystem and other platforms to follow

We are a forward-thinking team that embraces modern efficiency: you will be expected to leverage AI tools like Claude Code and Cursor to accelerate development speed, streamline refactoring, and maintain high-velocity output without sacrificing quality.

• Data Strategy: Design clean data models and persistence layers, managing integrations between Wix Data, external SQL/NoSQL databases (Supabase/Firebase/Postgres), and caching strategies.

Wix Ecosystem & Integrations

• Wix App Development: Build and maintain Wix apps using the Wix CLI, creating seamless dashboard extensions, admin UIs, and backend services.
• Deep Integrations: Utilize the Wix SDK and Platform APIs to interact with Wix Stores, Orders, Collections, and eCommerce domain objects.
• Feature Implementation: Build complex logic such as:
• Configurable settings panels and custom admin dashboards.
• “Additional Fees” logic and complex product-based rules.
• File upload and attachment flows.
• Service plugins and validation flows (e.g., shipping address verification).

Requirements (Must Have)

• Self-Hosted Infrastructure: Experience setting up and maintaining self-hosted Node.js applications (deployment, server management, environmental configuration).
• AI Adaptability: Enthusiasm for and experience with using AI tools (Claude Code, Cursor) to speed up coding tasks.
• Languages: Node.js, TypeScript, JavaScript
• Infrastructure: Self-Hosted Node.js environments, REST APIs, External DBs (Supabase/Firebase/etc.)
