Job Description

We help the world run better
At SAP, we keep it simple: you bring your best to us, and we'll bring out the best in you. We're builders touching over 20 industries and 80% of global commerce, and we need your unique talents to help shape what's next. The work is challenging – but it matters. You'll find a place where you can be yourself, prioritize your wellbeing, and truly belong. What's in it for you? Constant learning, skill growth, great benefits, and a team that wants you to grow and succeed.

This is growth, not replacement. We’re not just offering a job, we’re inviting you to shape the future of cloud-native infrastructure at SAP and in all of Europe. We have committed to open source by donating our projects into the neutral NeoNephos foundation. Make your mark, invite others, and discover #SAPEUAICloudCareers. Let’s build what’s next together.

Gardener powers SAP’s global landscape and is trusted as the foundation for countless enterprise workloads at SAP and outside. We adopt the Kubernetes open-source system for automating deployment, scaling, and management of containerized SAP solutions and business applications. We provide solutions to run and orchestrate Kubernetes clusters on public cloud, hybrid or SAP-owned infrastructures for a variety of enterprise use cases inside and outside of SAP.

Our Security and Agent Sandbox Development Team is contributing to the Gardener and other community projects (e.g. OpenShell) with a variety of topics around Kubernetes, Linux and Container Security Hardening, including networking, Linux Нamespaces & Cgroups, SecComp, eBPF, Landlock, etc.

We’re building ApeiroRA, an open-source reference architecture that strengthens Europe’s digital sovereignty. This initiative is part of a broader movement to ensure security, sustainability, and compliance for cloud-to-edge computing. By joining us, you’ll contribute to a project that’s not just technical, it’s strategic for Europe’s future.

What you'll do

  • Contribute (design and implement enhancements) in Gardener and AI agent sandbox solutions like OpenShell.
  • Implement Kubernetes controllers in Go.
  • Implement Gardener Extensions, write Gardener Enhancement and Security Enhancement Proposals (for seniors and experts).
