Senior .NET Developer

Joining the Integration Hub team, you'll design and build the messaging and caching backbone that keeps a large, mission-critical environment connected and reliable.

• Build the integration layer. Design and build a transversal integration layer centered on messaging and caching, using RabbitMQ, NServiceBus and distributed caches, to enable reliable and scalable communication and data storage across systems.
• Model & architect. Design a coherent physical data model and apply best practices in message queuing, routing and cache management, aligned with business and system architecture requirements.
• Operate & secure. Set up, administer and troubleshoot messaging tools and cache solutions, and safeguard performance, reliability and security through CI/CD and automated unit & integration testing.
• Collaborate & support. Collaborate with other IT teams, external partners and business stakeholders during project phases, and deliver first- and second-line support for production environments.
• Grow the team. Contribute to team maturity, technical knowledge and efficient documentation around messaging and caching infrastructures.

• 5+ years of experience on the .NET / Microsoft platform (Azure cloud, Databricks).
• Extensive experience with messaging systems such as RabbitMQ and NServiceBus.
• Proficiency with distributed caches and cache patterns.
• 3+ years with integration frameworks, especially message queuing and routing.
• Strong knowledge of automated unit & integration testing and CI/CD pipelines.

• Team player with an Agile mindset and strong communication skills across technical and business profiles.

What would makes you stand out as candidate:

• Experience administering and troubleshooting messaging environments across Windows and Unix platforms.
• A performance-oriented approach: analysing performance test results and optimising message and cache performance., * A craftsmanship culture. They're a true learning organisation. Senior profiles mentor juniors the way master craftsmen pass on their trade, with weekly knowledge-sharing sessions and workshops where each expert presents real use cases to the rest of the team.

• Continuous coaching, start to finish. Their support starts during the interview process and continues throughout the mission. You're never "sold and forgotten" at a client: when something needs solving, the team sits down together, finds a solution, and you carry on.
• Real people, real trust. A genuine human side and trust-based flexibility, where you manage your own hours as long as the work gets done. It's still a small, transparent, family-feel company where profit is reinvested into the people and the business.
• Substance over buzzwords. They specialise in data and work for the business, not just for IT. No AI hype for its own sake; they believe sound data governance comes first, so the solutions you build actually create value.
• Concrete package. Employee package includes a company car, meal vouchers, a 13th-month salary and team-building activities. Freelance is also possible.
