Shaping the future of cloud at Luminus – with you at the heart 

As a Cloud Azure Architect, you will design and grow our Azure cloud environment into a robust, scalable, and secure platform. You’ll bring structure, clarity, and fresh ideas — while collaborating with colleagues across IT to ensure our cloud supports business continuity, efficiency, and innovation. Your role is not about ticking every box on day one, but about bringing the mindset, adaptability, and communication skills to evolve with us and make a real impact.

• Design resilient, cost-effective cloud and hybrid solutions using the right mix of IaaS, PaaS, and SaaS. 
• Regularly review existing architectures and suggest improvements to enhance performance, security, and cost optimization. 
• Act as a technical reference point for Azure topics, representing Luminus in discussions with EDF Group and external partners. 
• Ensure business continuity for critical applications, even after disruptive incidents. 
• Present and explain your solutions clearly to both technical and non-technical audiences — clarity and influence matter here. 

What you bring 

• One year of hands-on experience with Azure cloud in a professional environment (experience in AWS is also welcome), plus a solid IT infrastructure background (networking, systems, or similar). 
• Azure or AWS certification is a plus, but your willingness to grow and learn counts even more. 
• Knowledge of CI/CD tooling and Infrastructure as Code. 
• Strong communication and presentation skills — you can structure ideas and get your point across with impact. 
• A collaborative, open mindset — you share knowledge, support your team, and welcome feedback. 
• Curiosity and adaptability — you’re eager to learn, whether it’s AWS tomorrow or new Azure services next month. 
• You are fluent in English and speak either Dutch or French at a professional level. 

Why join us 

• You’ll be part of a team that values teamwork, with knowledge sharing and collaboration at its core. 
• Your role will have real impact in shaping our cloud strategy while giving you room to grow into multi-cloud expertise. 
• You’ll join a company where IT is critical to our mission, but where work-life balance and long-term investment in people come first.
