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.

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.
