About Us

We are the central IT service provider for a group of companies (eGroup) including the well-known brand ebuero AG. Our IT Operations team supports over 1,200 users across 22 offices worldwide and two data centers. Our own SaaS and telephony platform handles tens of thousands of calls every day for customers in eight countries. We manage a diverse infrastructure with Linux, Windows, and macOS systems, and provide comprehensive IT services for the entire group.

What you'll be doing

• You run the Linux infrastructure behind our product platform on VMware/Proxmox in our own data center – stable operations come first.

• You drive the move of our platform to containers and Kubernetes, together with our DevOps colleagues.

• You keep our core services running and develop them further: DNS, mail (Postfix), load balancing (HAProxy), proxies and web servers, and our monitoring and logging (Icinga2, Grafana, Graylog).

• You support our developers with build pipelines and test environments (Bitbucket, Jenkins).

• You automate wherever it makes sense: configuration management with Puppet, Ansible and Foreman, infrastructure with Terraform.

• You take care of patching, hardening and vulnerability findings, and document your work so it holds up in our ISO 27001 audits.

• You start with a structured onboarding alongside our team and grow into owning topics on your own.
