Senior Cloud Engineer - Platform Infrastructure (m/f/x)

Our team builds and maintains the foundational infrastructure services used across the Dynatrace Platform.

We're looking for an experienced Cloud Engineer to join our Platform Infrastructure team with a focus on Application Networking. You will be working with service mesh technologies, DNS automation, certificate management, and application load balancing to deliver a secure, observable, and resilient connectivity layer for our Kubernetes-based platform — at scale.

This role is perfect for someone who enjoys developer-side Kubernetes work, designing Istio service mesh policies, automating certificate lifecycles, and shaping how internal and external traffic flows across our platform.

• Deploy, operate, and maintain core application networking components on Kubernetes (Istio, LoadBalancer, External-DNS, cert-manager).
• Design and enforce mTLS policies, traffic management rules, and authorization policies within the service mesh.
• Manage the rollout and migration of workloads from Istio sidecar to Ambient Mesh mode.
• Automate DNS record lifecycle across cloud providers using External-DNS.
• Own certificate lifecycle management and PKI integration via cert-manager.
• Configure and maintain application load balancing using Kubernetes Gateway API and cloud-native ingress solutions.
• Automate deployments using CI/CD and GitOps principles (ArgoCD, ArgoWF, Jenkins).
• Collaborate with platform and product teams to provide secure, reliable, and observable service-to-service communication.
• Work with major cloud providers (AWS, Azure, and GCP) to ensure resilient networking across environments.
• Participate in troubleshooting and incident resolution for networking and connectivity services.
• Continuously improve service monitoring and observability for mesh and networking components.

Must Haves:

• Deep knowledge and proven hands-on experience with Kubernetes networking and micro service architecture.

• Developer-oriented Kubernetes networking knowledge (Services, Ingress/Gateway API, NetworkPolicies).

• Experience with certificate management and DNS management.

• Familiarity with CI/CD and GitOps workflows.

• Experience with AWS, Azure, or GCP networking (at least one — VPC, load balancers, DNS, private connectivity).

• Solid understanding of TLS/PKI concepts (certificate issuance, rotation, trust chains).

• Basic understanding of Kubernetes Operators principles (CRD, Reconciliation)

• Terraform/OpenTofu experience for cloud networking resources (infrastructure currently partly managed this way — migrating towards more operators)

Nice-to-have:

• Monitoring & observability experience for service mesh.

• Experience with any of these technologies: Kafka, PostgreSQL, Vault, RabbitMQ, Redis, External Secrets Operator (ESO) or Kyverno.

• Dynatrace is a leader in unified observability and security.
• We provide a culture of excellence with competitive compensation packages designed to recognize and reward performance.
• Our employees work with the largest cloud providers, including AWS, Microsoft, and Google Cloud, and other leading partners worldwide to create strategic alliances.
• You'll get to work at the forefront of innovation with Dynatrace Intelligence—the industry's first agentic operations system. Bringing together deterministic and agentic AI, it helps teams understand what's happening, why it matters, and what to do next— automatically.
• Over 50% of the Fortune 100 companies are current customers of Dynatrace.

• Due to legal reasons, we are obliged to list a salary range for this position, which is € 61,000 up to € 76,000 gross per year based on full-time employment (38.5 h/week). We’ve listed the salary range for transparency, but if your experience and skills bring unique value, we’d still love to hear from you, please apply even if you’re outside the range.
