Constant learning, skill growth, great benefits, and a team that wants you to grow and succeed.

What you'll do

Build enterprise cloud infrastructure that provides European data sovereignty and hyperscaler-grade capabilities. You'll work on SAP Cloud Infrastructure, solving complex distributed systems challenges at scale: multi-region networking, container orchestration, observability, and the APIs that connect them. You will contribute to building a sovereign, privacy-first AI cloud for the European market that makes it easy to securely train, fine-tune, and deploy foundation and domain models with strict data residency and isolation. You'll develop solutions using Go, Kubernetes, and cloud-native technologies, tackling problems like: How do you autoscale thousands of workloads across clusters? How do you build resilient control planes and service meshes? How do you design APIs that handle massive traffic spikes? Your work will power SAP's production systems and thousands of customer environments. You'll contribute to infrastructure that enables organizations to run mission-critical applications with the performance and reliability they expect from leading cloud platforms.

In your role as Developer, you'll contribute to building SAP Cloud Infrastructure through hands-on development of enterprise cloud services that provide European data sovereignty and hyperscaler-grade capabilities. You'll implement features and components for distributed systems that handle significant scale, working on Kubernetes orchestration, networking, and storage solutions that power customer environments. You'll develop and maintain cloud-native infrastructure components using Go, Kubernetes, and related CNCF technologies, solving practical challenges in multi-region deployments, API development, and system integration. Your work will involve implementing features for auto-scaling clusters, building resilient workloads, and creating APIs that handle substantial traffic loads. Contributing to production systems that serve SAP's customer base, you'll help build infrastructure that enables organizations to run mission-critical applications with enterprise-grade performance and reliability. Your code will support European organizations in maintaining data sovereignty while accessing powerful cloud capabilities that compete with leading cloud platforms.
