Description du poste

Third line is where the tickets arrive that nobody else could close. This post covers a portfolio of commercial applications running on Windows and Linux servers: deploying them, integrating them with identity providers, keeping them healthy, and answering for them when they are not. Alongside the established estate there is genuinely new work - deploying and supporting AI-based tools and agents, and integrating them with the existing applications in production. Half of the working days each month are on site in Braine-l'Alleud.

What You Would Be Doing

• Deploy and manage server applications on Windows and Linux.
• Integrate applications with identity providers, and support client deployment to end-user workstations.
• Manage and configure Atlassian products across the estate.
• Maintain the operational and support environments, and monitor application performance.
• Manage identity groups and roles, and configure cloud components across Azure and AWS.
• Deploy, configure and support AI-based solutions and agents, and their integration with the applications.
• Provide second and third line support for end-user queries, and resolve software problems with minimal disruption.
• Monitor the incident process, keep tickets accurate and resolve within the service levels.
• Escalate to vendor support where that is genuinely the answer, and follow it through.
• Build the knowledge base and contribute to requirements analysis and change requests.
• Support security approval and accreditation of applications, and check compliance with the applicable regulations.

What you would bring

• Deep knowledge of Microsoft SQL Server and IIS-based web applications.
• Good knowledge of cloud deployment on both AWS and Azure, and a solid grasp of PKI and networking.
• Software engineering breadth: HTML5, REST and web services, XML, HTTP, SQL, plus identity integration with OAuth, OIDC or SAML2.
• Experience with IIS, JBoss or Apache Tomcat, and .NET applications.
• Extensive experience deploying and managing client-server applications and application integration.
• Strong troubleshooting and a genuine service orientation - this role is judged on how users get on.
• Full proficiency in English; French is an advantage.
