QA Automation Engineer – Join Euronext and shape capital markets in Athens.
Build end‑to‑end automated tests for enterprise‑grade clearing systems, driving quality and efficiency.
Join Euronext - Shape capital markets for future generations.
Euronext is the leading European capital market infrastructure, covering the entire capital markets value chain, from listing, trading, clearing, settlement and custody, to solutions for issuers and investors. Euronext runs MTS, one of Europe’s leading electronic fixed income trading markets, and Nord Pool, the European power market. Euronext also provides clearing and settlement services through Euronext Clearing and its Euronext Securities CSDs in Denmark, Italy, Norway and Portugal. In November 2025, Euronext successfully acquired a majority stake in the Athens Stock Exchange (ATHEX), further expanding its footprint and strengthening its pan-European market infrastructure.
As of December 2025, Euronext’s regulated exchanges in Belgium, France, Ireland, Italy, the Netherlands, Norway and Portugal host over 1,700 listed issuers with €6.7 trillion in market capitalisation, a strong blue-chip franchise and the largest global centre for debt and fund listings. With a diverse domestic and international client base, Euronext handles 25% of European lit equity trading. Its products include equities, FX, ETFs, bonds, derivatives, commodities and indices.
Euronext’s Technology & Operations teams cover a wide range of activities, including the operation of trading platforms and post-trade platforms, one Clearing House and four CSDs (prior to the integration of ATHEX). The IT function is responsible for designing, developing and testing new features and solutions to respond to the business and clients’ needs. IT also designs and builds the infrastructure that the company runs on and ensures that systems, infrastructure and market platforms are up and running.
IT teams provide end-to-end technology support across the Group, comprising approximately 800 staff primarily located in Milan, Porto, Paris, and the Nordics. They are organized into two main groups: IT Business Lines, which provide dedicated support to each core business, and IT Transversal Teams, including Infrastructure and Information Security.
Euronext’s 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.
