Sen. Developer/Development Expert (Go) (f/m/d) - Open-Source Cloud Infrastructure (IronCore) (T3+T4)

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.

What you’ll build

IronCore is SAP’s next-gen open-source cloud infrastructure on Kubernetes. It manages servers, storage, and networks with Kubernetes-native controllers to deliver a scalable, efficient platform powered by Software-Defined-Everything and hardware offload.

As a Senior Developer/ Development Expert (f/m/d) , you’ll build IronCore’s network‑fabric automation . Using Go , with occasional contributions in Ruby or other cloud-native scripting languages, you’ll design Kubernetes‑native operators that unify multi‑vendor physical network fabrics behind a single abstraction – enabling faster, more reliable provisioning, policy/intent‑driven automation, and self‑healing, AI‑assisted operations across IPv4/IPv6 data centers.

You’ll also help evolve adjacent areas – virtualization, storage, and bare metal – through end‑to‑end ownership (code → deploy → observe).

Your work will include:

• Building CI/CD pipelines and Infrastructure-as-Code (IaC)
• Operating and optimizing services in cloud environments
• Collaborating with distributed teams and OSS partners bringing Agile software engineering excellence into infrastructure development.

Most of your contributions will be open source and publicly visible.

What you bring

• 5+ years in Go (Rust a plus); strong Linux systems, performance & debugging.
• Kubernetes operators/CRDs: design and ship production reconcilers (controller‑runtime/Operator SDK).
• Networking: IPv4/IPv6, TCP/UDP/TLS, BGP; routing/security fundamentals and practical troubleshooting.
• SDN & fabric automation: integrate multi‑vendor network APIs/SDKs (gNMI, NETCONF, REST, gRPC); intent/policy modeling and drift detection.
• Cloud-native delivery: CI/CD and IaC (e.g., Argo CD, GitHub Actions, CDK) plus observability (Prometheus/OTel).
• Behaviors: ownership, clear communication, collaborative OSS mindset (please share GitHub ).
• Bonus: operating Kubernetes in production (managed or self‑hosted, incl. EKS/GKE/AKS).

Where you belong

The IronCore team is a diverse and experienced group of engineers passionate about distributed systems, Kubernetes, and open‑source infrastructure. Based in Munich and Walldorf, we work in a collaborative, feedback‑driven environment where individual ownership and deep system understanding are valued. Your expertise will shape the foundation of cloud infrastructure at SAP and beyond.
