QA Automation Engineer

The Euronext Technology & Support Centre

The ambition of the new Euronext Technology & Support Centre is to build a strong team in Greece that will support the Business Lines, IT, and Operations functions across the Group.

In its initial phase, the Centre will focus on two key initiatives:

Graphical User Interfaces (GUI) Development Team: We will establish an in-house team responsible for developing and supporting Euronext’s Graphical User Interfaces, which are currently managed by an external provider.

IT Clearing Test Factory: We will create an in-house Test Factory to support the Clearing House based in Italy. Euronext Clearing is a multi-asset-class clearing house that provides proven risk management capabilities for Euronext’s cash, financial and commodity derivatives markets. As the central counterparty (CCP) of choice for Euronext markets, it ensures the efficient and safe functioning of the markets.

Initial roles within the Centre will include Backend Developers, UI Developers, Business Analysts, Application Managers, and QA Engineers.
