What This Role Involves

This senior software engineer position at Euroclear, Brussels sits within the Group Business Solutions (GBS) division, which is responsible for designing and maintaining the IT solutions that power Euroclears financial securities operations. You would be stepping into a role that combines deep technical work with leadership responsibilities — not people management, but technical mentorship and architectural guidance.

On a day-to-day basis, you would drive the design, architecture, and implementation of technical solutions across complex, enterprise-grade systems. This means owning features end-to-end, collaborating with senior developers and cross-functional teams, and ensuring that what gets built is both robust and scalable. You would also mentor mid-level engineers, helping them work through difficult problems and raising the technical maturity of the team as a whole.

The role involves leading ideation workshops, defining and validating complex technical requirements for multi-team features, and anticipating dependencies to improve planning accuracy. Production stability is a core part of the job — you would independently lead technical investigations, deliver durable fixes, and proactively identify systemic issues. Note that some work outside regular business hours is required, as production launches typically happen after 5 PM or on weekends, and there are watch duties during nights and weekends as well.

Euroclear has set a high bar for this position. Here is what you need to bring:

• At least 10 years of solid experience as a software engineer
• Deep understanding of software-related system architectures and designs
• Strong knowledge of solution development and design principles
• Proven ability to analyse and interpret business requirements, anticipate technical implications, and create well-designed, scalable technical solutions
• Demonstrated experience with cloud migration, AI integration, automation, Infrastructure as Code, and CI/CD pipelines
• Strong coaching and mentoring skills
• Strong command of English, both spoken and written
• Experience on major projects and complex, large-scale systems
• Hands-on experience with IBM Mainframe technologies: PL/I, DB2, MQ, CICS
• Experience with Java or .NET development stacks, along with good command of APIs, integration mechanisms, and data technologies
• Experience with event-driven architecture principles and implementation using Kafka
• Experience with private cloud technologies, particularly Azure

Additional skills that would strengthen your application include experience with Linux Java development stacks, Docker, Kubernetes, Jenkins, GitHub Actions, Prometheus, Grafana, OpenTelemetry, and various programming languages such as Angular, C#, Spring Boot, Python, or COBOL. Knowledge of Agile methodologies, the Financial Services industry, or Machine Learning and Generative AI would also be valuable.
