(Senior) DevOps Engineer (m/f/x)

You work in a dedicated team on innovative solutions in a dynamic, product-oriented environment. You take end-to-end responsibility for our infrastructure and DevOps processes — from the Kubernetes platform and CI/CD pipelines through to monitoring, databases, and security.
Your tasks:

• Kubernetes & containers: operation and expansion of ourclusters — node setup, upgrades, deployments, troubleshooting, and application testing; onboarding of development teams onto the platform; management of Docker-based container solutions and their integration into the existing infrastructure
• CI/CD & GitOps: maintenance and further development of our GitLab environment, including pipelines, runners, the GitLab Agent for Kubernetes, and the Jira integration; GitOps-based delivery with ArgoCDor Flux
• Automation & Infrastructure as Code: provisioning and configuration management with Terraform and Ansible
• Databases: installation, configuration, maintenance, and troubleshooting of our database systems
• Observability: setup and operation of ELK / TIG / Grafana Alloy stacks — installation, configuration, dashboards, and alerting
• Networks & diagnostics: analysis and optimisation of our networks; log file analysis and systematic root cause analysis, up to and including complex incidents at packet level
• Security: security checks at application and infrastructure level, plus security gates in the pipeline (SAST, dependency/SCA scanning, secretsdetection, SBOM generation, artifactsigning)

• A degree in computerscience, a STEM subject, or an equivalent qualification gained through several years of professional experience
• Strong Linux skills and solid networking fundamentals (TCP/IP, DNS, TLS, MTU/routing) with proven troubleshooting ability
• At least 3 years of hands-on Kubernetes experience in production environments, along with container technologies (Docker/OCI)
• Hands-on depth with GitLab CI/CD or comparable systems, and with GitOps tooling such as ArgoCDor Flux
• Practical experience automating infrastructure and configuration as code with Terraform and Ansible
• Excellent analytical and debugging skills, with a structured, detail-oriented way of working
• A collaborative mindset: you enjoy developing solutions together, document your work, and share knowledge across the team

Nice to have:

• Experience with a specific cloud platform (OCI, Azure, AWS, or GCP) and with migration projects
• Familiarity with Dev Sec Ops toolchains such as Sonar Qube, Sonatype Lifecycle, Trivy, or Cosign/Sigstore
