Senior Network Engineer

Role Summary Cloudflare operates one of the world’s largest interconnected networks spanning 335+ cities worldwide. We are looking for a Senior Network Engineer to join our Edge Network & Backbone team. In the first year this role is intentionally hands‑on: you’ll own complex faults, drive capacity work, and set the standard for network operations. Beyond the trenches, you’ll help shape the team’s tooling by building AI‑enabled solutions that reduce toil and accelerate troubleshooting. Role Responsibilities Own the technical operation, engineering, and architecture of Cloudflare’s global network, including planning, installation, and day‑to‑day management of hardware and software across the edge and backbone. Serve as a hands‑on operational anchor, diagnosing and resolving complex network faults, owning end‑to‑end incident response (including on‑call rotation), and contributing to post‑incident reviews for continuous improvement. Build production AI agents for network operations: design, ship, and own LLM‑powered tools that integrate with operational systems via tool calling, with observability, cost tracking, and human‑in‑the‑loop checkpoints for autonomous action. Apply AI to accelerate troubleshooting by using Cloudflare’s internal AI platform to speed up root cause analysis, pattern recognition across faults, and operational decision‑making under pressure. Architect network improvements that lower latency, reduce packet loss, and increase scale, optimizing end‑user experience across the global infrastructure. Mentor and develop junior engineers, setting technical standards, leading structured troubleshooting sessions, and fostering a culture of operational excellence and continuous learning. Collaborate with internal teams on cross‑functional network projects, contributing to design documentation, SOPs, and knowledge‑base articles that outlast any individual contributor. Role Requirements (Must‑Have Skills) Proven track record in large‑scale network engineering and operations. Proficiency in Python and/or TypeScript and/or Go sufficient to build, debug, and maintain agent code. Working knowledge of agent integration patterns: function/tool calling, MCP or equivalent, retrieval over operational corpora, and prompt iteration with evaluations. Experience reasoning about agent failure modes in production (hallucination guards, fallback paths, rollback, blast‑radius control). Deep expertise in BGP and anycast routing with the ability to diagnose and resolve complex routing issues. Strong understanding of MPLS and Segment Routing. Experience with network automation frameworks such as SaltStack, Ansible, or equivalent, and a strong instinct for solving operational problems through code. Ability to prioritise effectively and lead calmly under high‑pressure scenarios. Effective communication skills to adapt style to any audience, from guiding junior engineers to presenting architecture decisions to senior leadership. Nice‑to‑Have Skills Shipped LLM‑powered tooling into production with measurable operational impact. Professional‑level network certification (JNCIP, CCNP, or higher). Experience with optical transport technologies such as CWDM and DWDM. Experience writing network configuration and design documentation at an architectural level. What Makes Cloudflare Special?
