This role combines deep technical leadership with end-to-end product ownership, direct influence with key customers, and the opportunity to mentor the next generation of cloud networking engineers.
KEY RESPONSIBILITIES
• Oversee a significant component of the cloud networking platform, the cloud networking and security platform, defining control-plane and data-plane standards for routing, NAT, traffic steering, and firewall enforcement at cloud scale.
• Architect multi-cloud and hybrid networking topologies, including VPC/VNet segmentation and hub-and-spoke and mesh designs, aligned with zero-trust security principles.
• Lead the design of routing-centric systems and next-generation firewall data planes, including BGP route exchange, policy-based routing, and large-scale NAT, ensuring correct behaviour across asymmetric routing, NAT traversal, and multi-path traffic.
• Drive delivery from concept through production by writing design docs for ambiguous, cross-component problems and leading design reviews focused on correctness, performance, and scalability.
• Regularly lead cross-team projects where decisions directly affect major organizational objectives. Identify and drive improvements to reliability, performance, and security as the senior technical authority for complex networking issues, including participation in the on-call rotation.
