Technical Team Lead — Enterprise Application Support and Cloud Integration for NATO with security clearance

Technical Team Lead — Enterprise Application Support and Cloud Integration for NATO with security clearance Lead a small technical team and stay in the code — COTS application portfolio, Azure and AWS, with genuine ownership of the technical quality of what ships. This is a lead role for someone who does not want to stop being an engineer. You would own the technical quality of a team's output across a portfolio of commercial applications, and the requirement is explicit that a meaningful share of your time — roughly twenty to forty per cent — stays hands-on, so you remain credible and can unblock people yourself. The estate is a mixture: server applications on Windows and Linux, .NET and Java stacks, SQL Server behind IIS web applications, and a growing amount of cloud configuration across Azure and AWS. Identity work is a constant theme, and there is early work on integrating AI capability into the commercial applications. What you would be doing Coordinate, deploy and manage server applications running on Windows and Linux. Own the technical quality of the team's output, and keep a real hands-on share of the work. Manage identity groups and roles, and configure cloud components across Azure and AWS. Support the integration of AI capability into the commercial application portfolio. Coordinate support activity against the service levels, and resolve the complex issues yourself. Run incident logging and tracking properly, and escalate to vendors when that is genuinely the answer. Build the knowledge base — document what broke and what fixed it, and share it. Implement the security baselines and architecture patterns set by governance, and produce the compliance evidence. Support change, configuration, release and test management. Work with product owners, delivery managers and suppliers, translating technical constraints into business language. What you would bring At least five years in technical delivery, including a year or more leading a team, formally or in practice. Strong hands-on depth in a modern stack — .NET, Java or Python, cloud, containers and Kubernetes, CI/CD, SQL and NoSQL, infrastructure as code. Expert knowledge of Microsoft SQL Server 2019 onwards and IIS-based web applications. Good knowledge of cloud deployment on both AWS and Azure, and a solid grasp of PKI and networking. At least four of HTML5, REST and web services, XML, HTTP, SQL and VBA, plus identity integration with OAuth, OIDC or SAML2. Experience with IIS, JBoss or Apache Tomcat and .NET applications. Practical service management along ITIL lines: incident, problem, change, release. Demonstrated people leadership — coaching, structured feedback, and handling the difficult conversations. Full proficiency in English; French is an advantage. Half of the working days each month are on site in Braine-l'Alleud.
