The Network teams, together with the Development teams, are forming a new squad to build the company's Network Function Virtualisation (NFV) system. It will become the base pillar to sustain our data centres and Operations work and enable the development of our future products. Our international team breaks barriers and brings the European digital future ahead. This is a position for those interested in building the foundation of The European Cloud Provider.

You will contribute to making IONOS the biggest European Cloud competitor.

☁ Your Role

• Develop and maintain modern, scalable Virtual Network Functions (VNF) for IONOS Cloud using Go (primary) or C/C++.
• Design and implement new features while integrating cutting-edge networking technologies such as Open vSwitch, OpenFlow, VXLAN, VRF, and eBPF.
• Solve complex problems like distributed scalability, real-time traffic handling, and node optimization.
• Collaborate with other teams to seamlessly integrate VNFs with IONOS products.
• Work on architecture design, POCs, and decision-making for key features and enhancements.
• Participate in daily stand-ups and a Kanban-based workflow to ensure smooth progress on projects.

☁ What Makes This Role Exciting?

• Technical Freedom: You’ll have the autonomy to make design decisions and directly influence the architecture of critical VNF services.
• Diverse Challenges: Work on scalable systems, virtualised infrastructure, and advanced networking technologies to tackle real-world customer needs.
• Collaboration with Experts: Join a team of highly skilled professionals across domains such as Linux, networking, and cloud systems, where knowledge-sharing is highly encouraged.
• Continuous Learning: Access a wealth of resources, including training videos, recommended books, and opportunities to deepen your knowledge in Go, Kubernetes, and advanced networking.

☁ What You Bring to the Table

• 3+ years of experience in software/system development.
• Advanced programming skills in Go (mandatory) and/or C
• /C++.Familiarity with Go frameworks/tools like Gin, Echo, gRPC, or Go modules is a plus.
