JavaScript Developer for Firebase Functions and API Integrations

We are looking for a JavaScript developer to help maintain and extend a cloud-based integration system. The backend is built using Firebase Cloud Functions and relies on secure API communication and structured data mapping.

This is ideal for a developer who enjoys structure, values clean code, and wants to contribute to a project with long-term potential.

Responsibilities:
- Write and maintain backend functions in Node.js using Firebase Cloud Functions
- Handle event-based automation and REST API integrations
- Process JSON payloads using predefined mapping structures
- Maintain dispatcher-based architecture with consistent module structure
- Create and maintain clear documentation for the codebase


*Requirements:
- Strong JavaScript and Node.js experience
- Solid knowledge of Firebase Cloud Functions
- Go High Level experience is a big plus
- Experience working with APIs, webhooks, and JSON payloads
- Understanding of async/await, try/catch, and structured logging
