We are looking for SW engineers who wish to be a part of developing and evolving the current and next generation of routers that form the core of anything internet. These routers are at the heart of Nokia's IP product offerings, from data centers (including AI fabrics) to providing strong, resilient low latency and dependable IP backhaul for service providers and mission critical networks. In this role, you will have the opportunity to work with one of the best engineering teams in the industry. We value your expertise and offer an environment where you can thrive both professionally and personally. There are more customers we want to win, more networks to penetrate, more technologies to enable and more applications to support. We want to make smaller products, and we want to make bigger products. We want to build products based on newer standards and newer ASICS in the market.
You will play a critical role in designing and implementing high-performance data path solutions on both custom and merchant silicon. You will be responsible for writing efficient and modular code that is well-tested and robust, ensuring that it meets the high standards required for the most critical networks. Your role will involve working on advanced packet forwarding techniques in IP, MPLS, Segment Routing, VxLANs. You will also contribute into Traffic Management technologies - QoS (Policers, Schedulers, Shapers), ACLs, TCAM Management, and Packet Extractions to CPU. DCN2026.

How You Will Contribute And What You Will Learn

• Design and implementation: You will gain deep expertise in designing and implementing datapath solutions on both custom and merchant silicon.
• Advanced packet forwarding: Develop your skills in IP, MPLS, Segment Routing, VXLANs, and QoS technologies such as Policers, Schedulers, and ACLs. DPDK and performance optimization: You'll be working with DPDK and similar technologies to maximize performance for high-throughput systems.
• Virtualized environments: Expand your knowledge in working with virtualized Linux environments such as KVM and Dockers.
• Team collaboration: Work closely with cross-functional teams, including product management and software testers, to deliver customer-driven solutions.
