• Design and evolve our cloud architecture on GCP - networking, interconnects, IAM and high-availability topology - and express it entirely as code with Terraform, following GitOps as a first principle. • Build and own the CI/CD pipelines that plan, review, test and safely apply IaC changes - Policy-as-Code guardrails, drift detection and progressive rollout so infrastructure changes ship as confidently as application code. • Advance Platform-as-a-Product: build self-serve capabilities and paved paths so engineers can provision what they need, through a golden path rather than a hand-off. • Strengthen our observability stack - metrics, logs, traces and alerting across Prometheus, Thanos, Grafana, Loki, Tempo and Alertmanager - so the platform is easy to run and reason about. • Operate our GKE clusters and the infrastructure services that run on them - Helm-packaged workloads, message brokers (RabbitMQ, IBM MQ) and data stores. • Participate in our Follow-The-Sun on-call model: watch and triage alerts, join and declare incidents, lead structured debugging and escalation, and drive blameless post-mortems and the post-actions that actually close the loop. • Embed SRE practices - SLIs/SLOs and error budgets, capacity planning - into how Core Infrastructure builds and operates, working closely with our SRE function.

• Improve the tooling and automation of our infrastructure to minimize manual work, increase performance, and decrease the frequency and severity of incidents • Build, maintain, and support core applications • Monitor our systems for capacity, performance, and troubleshoot issues • Partner with the rest of the SRE team to ensure smooth, continued delivery of our service to clients • Demonstrate a high level of autonomy in anticipating, identifying, and addressing systemic weaknesses and opportunities for platform improvement

• 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
