Технический консультант .NET

One of our clients in Antwerp is actively modernizing its application architecture. AE plays a key role in this transformation. Based on the existing .NET environment, we are creating an updated application landscape where Domain Driven Design, clear service boundaries, and event-driven communication are central.

This is more than just a technical upgrade. It's a structural step towards a future-proof IT organization – and you will help build its core.

AI at AE – what does that mean for you .NET developers at AE are already actively using AI assistance: Claude and GitHub Copilot for code generation, code reviews, and documentation are everyday tools, not just gadgets. In this project, we're going a step further: you'll think about how AI can structurally add value to software development – from automatically generated tests to AI-integrated application components. We don't expect you to be an expert in this area from day one – we're looking for your openness and the right mindset.

What will you focus on?

• You will work full-time as a .NET developer on a long-term modernization project: analysis, design, and implementation will form the basis of your daily work
• You will write high-quality code and actively participate in code reviews, testing strategy, and best technical practices
• You will be involved in discussions about architectural issues – bounded contexts, service decomposition, integration patterns – and share your insights within the team
• You will work in an environment where Domain Driven Design and event-driven communication are applied in practice, and you will grow along with the project
• You will consider cloud and containerization principles without managing the platform itself

Who are you?

• A minimum of five years of experience as a .NET developer in complex or business-critical environments
• Deep knowledge of C# and ASP.NET Core; microservices and distributed system patterns are familiar to you
• A combination of technical depth with a hands-on mentality: being close to the code and thinking about how processes can be improved
• Confidence in working within a corporate environment where scalability, security, and compliance are daily conditions
• Clear communication within the team, willingness to share knowledge
• Fluent in Dutch

Bonus points for:

• Experience with or a clear interest in Domain Driven Design and event-driven architecture
• Familiarity with messaging platforms (NServiceBus, RabbitMQ or similar)
• Initial experience with AI tools in the software development workflow

What does AE offer?

• A key role in a strategic modernization project where architecture and technical choices truly matter. You will work in a strong team of experienced engineers, tech leads, and architects with whom you can discuss DDD, event-driven architecture, and enterprise design at a high level.
• An environment where not only technology, but also the professionalization of teams and the organization, is central
• Over 400 colleagues in a fast-growing Belgian organization – head office in Leuven, with branches in Groot-Bijgaarden, Berchem, Ghent, and Hasselt
• Knowledge sharing, mentoring, and personal growth are structurally embedded – not as a promise, but as a daily practice
• AE is 'Best Belgian Employer 2025' with a Great Place To Work certificate
