Group Business Solutions (GBS) – Solution Engineering 

The Group Business Solutions (GBS) division ensures the competitiveness of Euroclear by delivering reliable and sustainable IT solutions for the financial securities markets. Our technical teams deliver new IT solutions and improve existing applications for both our internal and external clients. We deploy changes into the production environment in a controlled and structured way that doesn't compromise production stability and we ensure applicative production support.  

Within GBS, you will join the Solution Engineering team where you can play a key role in modernisation of the engineering practices for the IT divisions.  

The Java Centre of Excellence (CoE) defines, promotes, and continuously improves the engineering standards, frameworks, and golden paths used to build backend services and business applications across Euroclear’s Java ecosystem. 

The CoE provides: 

• A clear, opinionated, end‑to‑end way of working for Java development, covering coding standards, architecture patterns, testing, CI/CD, observability, security, release processes, and best practices across the SDLC. 

• A robust, modern, and supported Java framework, including reusable components, libraries, guidelines, platform governance, and engineering excellence standards for the Java community. 

As a Lead Expert Engineer, you will contribute hands‑on to the CoE’s framework evolution, influence technical direction, and ensure our standards are practical, usable, and adopted across squads. 

Your Role 

As a Lead Expert Engineer within the Java CoE, you act as a senior hands-on technical expert who turns strategy into practical, reusable, high‑quality engineering solutions.

You contribute directly to the CoE’s technical assets—including frameworks, libraries, training paths, and others—and help squads apply these assets effectively to deliver secure, scalable, and robust Java solutions across Euroclear.  You will contribute the set up of the CoE.
