Senior Network Security Engineer

You will own incidents end-to-end across Incident, Major Incident, Change, Problem, and Service Request workflows (ITIL-aligned), leading real-time response to live DDoS attacks and complex network events as they unfold. Day to day, that means performing advanced 1st-3rd line triage and troubleshooting across the platform and customer environments, acting as a subject matter expert on our real-time mitigation technology, and serving as the technical escalation point for junior engineers. You will work directly with customers and partners during high-impact incidents, collaborate closely with Engineering, Product, and Threat Intelligence to feed insight back into the platform, and drive the documentation, runbooks, and operational improvements that raise the bar for the whole team. Mentoring junior engineers and continuously deepening your own networking and DDoS expertise are part of the job, not an extra.
