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.
