Frontend Developer (React)

About Project

The project involves taking over the maintenance and development of an existing billing and usage-tracking platform used for automated invoicing based on collected consumption data from infrastructure systems.

The scope includes technical ownership of the current solution, implementation of system adaptation due to changes in the external contract management platform, and development of a new integration to ensure full continuity of billing processes.

The platform consists of a data ingestion layer, database logic, backend API and internal frontend interface. Data is collected from multiple enterprise sources, normalized, and processed for invoice calculations. The project requires maintaining high accuracy of financial output, and seamless migration to the new integration endpoint within a defined MVP.

Role Overview

• Update frontend components communicating with Embla API.

• Ensure alignment of UI logic with backend integration model.

• Support regression and UI testing.

• In post-MVP phases: improve usability and support functional enhancements during Go-Live.

Requirements:

• 4-5 + years in React (TypeScript preferred).

• Experience in REST API integration and enterprise web applications.

• Understanding of authentication mechanisms (ideally SSO / Entra ID).
