• Ensure the operational maintenance of systems while anticipating necessary evolutions to adapt them to future needs.
• Participate in technological watch and propose relevant evolutions to advance the technical environment, particularly in terms of simplification and automation.

2. Infrastructure management

• Collaborate in managing the datacenter and associated equipment (servers, storage, virtualization, etc.).
• Install and configure servers according to established procedures and FHVi best practices.
• Manage the lifecycle of Microsoft ecosystem components: update planning, version upgrades, service renewals, decommissioning obsolete systems.
• Supervise systems via monitoring tools and ensure infrastructure resilience and security.

3. Support & documentation

• Provide level 2 and 3 support, linked to requests and incidents reported via the service management tool.
• Document procedures, configurations, and best practices to ensure knowledge sustainability within the team.
• Participate in the on-call service according to current arrangements.
