System Architect – Routing and Data Path

Description Ra'anana, Israel | Hybrid Why DriveNets DriveNets powers the networks that move the world - over half of AT&T's backbone runs on our platform, and Comcast has deployed us nationwide. We just closed a $410M Series D ($1B raised total, cash-flow positive since 2025), backed by Bessemer, AMD, and Broadcom. We're not just scaling SP routing- we're wiring the next era of AI infrastructure, solving the most expensive idle-asset problem in tech: a GPU waiting on the network. The Role You'll join our System Architecture group and own end-to-end design of a hyper-scale router Software - DNOS. From customer requirements through deployment. Expect deep cross-functional collaboration, hands-on spec leadership, and direct customer engagement at the architecture level including leveraging AI tools to produce high-quality specifications. You will: Define system requirements and lead architectural design across routing and data path Drive spec reviews and guide engineers through design decisions Establish design standards that improve resilience, security, and efficiency at scale Requirements What We're Looking For BSc in CS or EE; 4–5 years software development + 2-3 years system architecture experience Strong analytical thinking and the ability to own a spec from idea to production Networking/routing (L2/L3), data path (e.g. QoS, ACL), and data modeling knowledge are all a plus Familiarity with both AI data center and service provider network architectures is a strong advantage - our platform serves both worlds Not a perfect match? Apply anyway - we hire for potential and perspective, not just checkboxes.
