your tasks

What it's about

In L2 support you are the technical reference. You process tickets like everyone else, but you also take on cases where standard measures no longer work. Multi-layered error patterns, performance problems, platform-related cases. At the same time, you drive the team forward: through standards, reviews and professional coaching. When there's a fire, you hold the technical threads together.

• Process more complex L2 tickets in day-to-day business; In-depth error analysis at application, system and platform levels
• Challenging topics: For example, virtualization/HA/storage-related cases, firewall/VPN, performance/stability problems, complex migrations
• Coordinating incidents: prioritizing, keeping track, deriving concrete improvements from disruptions
• Define standards: further develop runbooks, escalation rules, ticket minimum dates and support procedures
• Strengthen the team: coach L1/L2, review procedures, share knowledge

Platform and virtualization expertise: Experience with virtualized environments, HA concepts and storage (e.g. Proxmox, KVM, Ceph or comparable)

In-depth error analysis: Analyze and resolve complex faults at the application, system and platform levels. You think beyond the individual case and take into account dependencies and effects on other systems.
