• Design and maintain container-based deployment setups using Docker and related technologies • Define repeatable deployment and runtime models across cloud and hybrid environments • Build and maintain deployment and environment automation to ensure reliable and traceable operations • Support development teams with CI/CD pipelines, deployment automation, and release processes • Design and improve observability solutions (monitoring, logging, tracing) for reliable operations • Advise on infrastructure aspects such as networking, security, hardware requirements, and scalability • Work closely with engineering and product teams to ensure operability is considered early • Use AI-assisted tools to improve operational efficiency while critically validating their outputs

• Monitor, maintain, and improve system availability in a cloud production environment. • Ensure the stability and availability of cloud production systems. • Perform monitoring, alerting, and incident response. • Automate recurring operational tasks and contribute to infrastructure improvements. • Troubleshoot complex issues related to performance, system reliability, networking, and service integrations. • Collaborate with development and operations teams to enhance system performance and reduce operational risks. • Participate in on-call rotations and continuous improvement initiatives.

• Manage and administer our operations tools (e.g., Sentry, CheckMK, GitLab) • Ensure monitoring via CheckMK and continuously develop it • Maintain and enhance our Proxmox and Azure systems • Support the on-premises and corporate networks (routing, port forwarding, VLAN management, VPNs) • Administer access rights and implement automated access management concepts • Design and implement improvements to network architecture and security • Adapt and further develop GitLab CI/CD pipelines • Maintain and optimize AWX playbooks (Ansible) • Implement Infrastructure as Code (Terraform, Ansible) • Administer permissions (Entra ID / Azure AD, third-party applications)

• Improve the reliability, resilience, and operational readiness of our services • Work closely with engineering teams to improve system design and operational excellence • Prevent incidents, lead response efforts, and drive improvements through post-mortems • Implement improvements to the reliability, fault tolerance, scalability, and performance of our infrastructure • Manage incidents using your technical know-how to involve the appropriate teams and automate away manual practices • Provide support to our critical services by responding to automated alerts through our on-call rotation • Define and maintain SLIs, SLOs, SLA, and error budgets to guide reliability decisions • Improve observability across our systems (metrics, logs, tracing) to reduce time to detection and resolution • Make production issues easier to detect, troubleshoot, and resolve • Improve monitoring, alerting, dashboards, tracing and runbooks for critical services • Lead postmortems and follow-up actions to reduce repeat incidents
