• Help application teams move toward more standard, supportable and modern operating patterns where appropriate.
• Act as a trusted advisor to application owners by building knowledge of the application, business context, dependencies and operational sensitivities.
• Support critical incident reviews where application infrastructure, middleware, platform or dependency knowledge is required.
Required experience
• Senior experience in application infrastructure, application operations, middleware, production engineering, application support or solution architecture.
• Strong understanding of how enterprise applications run across datacenter, virtualized, middleware, database, container and cloud environments.
• Experience evaluating legacy, non-standard and modern application stacks.
• Practical knowledge of application servers and middleware such as WebSphere, Tomcat, IIS, message queueing, Java, .NET, APIs and container-based platforms.
• Experience with operational readiness, dependency mapping, monitoring design, resilience, recovery planning and incident analysis.
• Ability to translate between application teams and infrastructure teams.

• Experience with application performance monitoring, observability, monitoring, IT service management and DevOps tooling.
• Familiarity with cloud platforms, Kubernetes, CI/CD pipelines, automation and infrastructure-as-code.
• German language capability useful for German plant-facing or operations-facing discussions.
