• You work closely with our clients from industry, the public sector and academia on demanding infrastructure projects, from planning through to stable operation. • You take on the architecture, setup and further development of cloud and on‑premises infrastructures, including public cloud environments such as AWS, Azure and GCP as well as platforms like Kubernetes and OpenShift. • You operate and maintain existing systems and data center infrastructures, including hybrid and multi‑cloud setups. • You analyze existing architectures and support the migration and modernization of legacy environments. • You set up GitOps and CI/CD workflows (e.g. with ArgoCD, GitLab CI, Azure DevOps) and guide our clients in automating their development and operational processes. • You provide consultancy on current technologies and best practices, particularly in containerization, cloud‑native tools and infrastructure-as-code (Terraform, Ansible). • You contribute conceptually to topics such as network design, storage architectures (e.g. Ceph, ODF, NFS) and security standards (BSI, ISO27001, IAM, PKI). • If desired, you will also support clients on‑site in Germany and assist our colleagues in the team with your expertise.

• Design and operate secure, scalable, and high-quality infrastructure that supports modern applications and advanced AI workloads • Build and maintain robust automation across CI/CD pipelines, infrastructure provisioning, and operational processes to improve reliability and minimize manual effort • Integrate AI-driven solutions into operational workflows to enhance efficiency, detect anomalies, and accelerate delivery • Apply strong systems engineering practices, including monitoring, incident management, performance optimization, and capacity planning • Establish and uphold DevOps best practices, ensuring reproducibility, testing, documentation, and operational excellence • Communicate technical decisions clearly and collaborate cross-functionally to support predictable delivery and effective problem-solving • Provide mentorship and technical leadership, raising the level of platform engineering, DevOps maturity, and overall engineering quality across the organization

• Mentor fellow engineers • Architect scalable infrastructure solutions • Build automated solutions • Respond to infrastructure support requests • Triaging and investigating complexities • Execute OS hardening and deploying infrastructure with Terraform • Communicate effectively with peers • Participate in agile ceremonies • Support patching operations on weekends

• design and build the infrastructure primitives that define how our CI/CD platform, build systems, and developer environments scale across the entire engineering org. • help build and operate the Kubernetes-based control plane behind our CI/CD platform, including: - GitHub Actions self-hosted runner infrastructure (autoscaling, isolation, cost/perf tuning) - GitHub Apps and GitHub-as-code (permissions, webhooks, org-wide automation) - Secure network access for CI/CD and remote dev environments (Tailscale) - GitOps-driven deployment of platform services (Flux) - Ephemeral/on-demand developer environments and build systems • develop the core infrastructure components — including Kubernetes Operators and scaling automation — that product teams adopt directly, reducing bespoke per-team CI/CD and environment tooling. • building the systems that define how engineering teams build, test, and deploy, shaping the reliability and scalability of the developer experience org-wide.
