What you`ll do

We are looking for a Backend & Cloud Infrastructure Engineer Expert (f/m/d) who brings deep backend development skills together with hands-on Infrastructure-as-Code expertise. You will own microservices end-to-end - from writing production-grade code to provisioning and operating the cloud platform that runs them. Your mission: make every deployment predictable, every environment reproducible, and every service production-ready.

You operate at the intersection of software engineering and cloud platform operations. On any given day you might be building a new microservice, tuning a Helm chart's rollout strategy, refactoring a Terraform module, or hardening a CI/CD pipeline. You are the person who ensures that what works locally works identically across all environments - from dev through production.

• Design and build microservices and REST APIs
• Write robust automated tests - unit, service-layer, and API-level
• Integrate with relational databases, optimizing queries and managing persistence layers.
• Participate in code reviews and uphold established coding guidelines.
• Own and evolve Terraform modules for the full platform topology: Kubernetes clusters, networking (VPC, NAT, DNS), managed databases, message brokers, CI/CD infrastructure, and cloud-provider services.
• Manage multi-environment deployments (dev, test, staging, production) with proper state management, secret handling, and drift detection.
• Maintain and extend Helm charts - service deployments, autoscalers (HPA), network policies, ingress/gateway routing, TLS certificates, PodDisruptionBudgets, and service accounts.
• Operate Kubernetes clusters - service mesh, certificate management, message queue operators, resource sizing, and zero-downtime rolling updates.
• Build and maintain CI/CD pipelines
• Implement and enforce security practices
• Automate cloud operations - environment provisioning, role/permission assignment, tenant onboarding, and landscape cloning via scripts.

• 5+ years combining backend development and infrastructure/DevOps engineering.
• Strong proficiency in a modern Java/Spring Boot, transactional semantics, REST API design, automated testing.
• Production Terraform experience (3+ years) - modular architecture, remote state, per-environment configurations, plan/apply workflows, state migrations.
• Kubernetes - deployments, services, HPA, PDB, network policies, RBAC, service mesh concepts, cert-manager.
• Major cloud platform (GCP, AWS, or Azure) - managed Kubernetes, networking, IAM, container registries, DNS.
• CI/CD pipeline engineering - Jenkins, GitHub Actions; Docker image builds; automated quality gates.
• Secrets management - SOPS, Vault, Sealed Secrets, or similar encryption-at-rest tooling.
• Networking fundamentals - DNS, TLS/mTLS, ingress routing, network policy design.

What we consider beneficial:

• Experience with SAP BTP, Cloud Foundry
• HANA or other SQL DB
• RabbitMQ / Kafka - operator-based deployment on Kubernetes, messaging reliability.
• Istio or similar service mesh - traffic management, observability, mTLS policies.
• Gradle - multi-module build configuration at monorepo scale.
• Monitoring & observability - Prometheus, Grafana, cloud-native monitoring, structured logging, alerting.
• GitOps practices - declarative infrastructure, drift reconciliation, PR-based deployment workflows.
• Cost optimization - resource right-sizing, autoscaling strategies, committed-use planning.
• Compliance & security hardening - private endpoints, image scanning, supply-chain security tooling.
