SAP started in 1972 as a team of five colleagues with a desire to do something new. Together, they changed enterprise software and reinvented how business was done. Today, as a market leader in enterprise application software, we remain true to our roots. That’s why we engineer solutions to fuel innovation, foster equality and spread opportunity for our employees and customers across borders and cultures.

SAP values the entrepreneurial spirit, fostering creativity and building lasting relationships with our employees. We know that a diverse and inclusive workforce keeps us competitive and provides opportunities for all. We believe that together we can transform industries, grow economics, lift up societies and sustain our environment. Because it’s the best-run businesses that make the world run better and improve people’s lives.

As a Senior/Expert Software Engineer (f/m/d) you will be a crucial part of the development of our Software Defined Network (SDN) infrastructure. You will code Container Network Interfaces (CNI) for Kubernetes pods, create and automate router configurations on the physical hosts and L3 switches (frr, GoBGP, SONiC) and find a solution for a resilient Layer 4 load balancer, that does not drop sessions when scaling horizontally. You will keep our network running, do performance benchmarks, evaluate user space networking and enhance our network stack continually.

Most of your code will be open source and written in Go and Bash – but we also love Rust and C/C++.
Collaboration with other SAP teams and partners in an international environment will be a regular part of your work.

  • Hands on experience with network configuration on AWS EC2, GCP or Azure
  • Good communication skills in German and English language


  • 5+ years of relevant work experience in a similar position in a Networking area – ideally Networking in Cloud context.
  • The ideal candidate would bring 5+ years of experience with Linux Networking.

About the Team
The Gardener on Metal team is a brand-new team currently in founding. We are a mix of backend and frontend software engineers and infrastructure experts with knowledge about network, Linux, Kubernetes and virtualization. The team is distributed over Munich and Walldorf. There is still a lot of shaping to be done and we would like you to be part of it.
Gardener on Metal - What it is all about
Gardener is an open source Kubernetes management solution by SAP. Gardener supports deploying Kubernetes clusters on different hyperscalers and proprietary virtualization platforms. Gardener follows an inception model: Managing Kubernetes with Kubernetes. With Gardener on Metal we bring this concept to the bare metal: manage physical servers and network infrastructure with Kubernetes to run Kubernetes clusters on top – providing them to SAP developers and customers. The classical virtualization layer is replaced by Kubernetes‘ cloud native approach. Modern networking concepts like eBGP in combination with a Clos topology guarantee highly performing and resilient connectivity.
