Our operations team keeps the platforms behind our solutions available, secure and up to date.

These solutions help make European aviation safer and more efficient. We work closely with development teams, data teams and the teams that run networks, servers and storage.

Role Overview:

This is a support-focused role. You provide second- and third-line support for the middleware and commercial products that our solutions depend on, and you install, run and improve them.

You are the team's reference for middleware and automation, and you support colleagues on our database platforms.

Our current technology stack is Apache, Tomcat, Nexus, Jenkins, ESRI ArcGIS Enterprise, SAS and Oracle on Red Hat Linux and Windows Server, automated with Ansible and Azure DevOps.

We value demonstrated experience over familiarity with the concepts.

Key Responsibilities:

• Resolve incidents and service requests and find the root cause of complex problems.
• Triage second-line requests on the team rota and route them to the right team.
• Install, configure, upgrade, patch and harden middleware and commercial products.
• Automate deployments, configuration and routine operations.
• Monitor performance and availability, and fix problems before they reach users.
• Evaluate new commercial products through proofs of concept and vendor support.
• Work with the network, server and storage teams to resolve dependencies.
• Write and maintain runbooks and operational guides.

What Success Looks Like in the First Year:

• Run the middleware platforms without help within 6 months.
• Automate the installation and upgrade of the main middleware products.
• Handle routine database tasks and second-line triage.

Required Skills & Experience:

• 5+ years supporting and administering middleware or commercial products in production.
• Strong Linux administration (RHEL or equivalent) and solid Windows Server administration.
• Proven experience installing and upgrading web and application servers, for example Apache HTTP Server and Tomcat.
• Configuration management with Ansible or equivalent, and scripting in Bash and PowerShell.
• Experience with CI/CD and build tools, for example Azure DevOps, Jenkins and Nexus.
• Hands‑on experience with containers, for example Docker, Podman, Kubernetes or OpenShift.
• Good understanding of networking, for example DNS, TLS, proxies, firewalls and load balancers.
• The ability to learn an unfamiliar commercial product on your own.
• Experience with ServiceNow or an equivalent ITSM tool, and the judgement to set incident priority by business impact.

Preferred Skills & Experience:

• Oracle Database administration, for example backup, patching and SQL.
• Oracle query performance troubleshooting and tuning.
• Azure web hosting and infrastructure as code, for example App Service, AKS and Terraform.
