  • Lead technical workshops, knowledge-transfer sessions, and special-event preparation, including product launches, traffic events, security drills, and quarterly business reviews.
  • Document decisions, runbooks, and configurations in the customer’s collaborative workspace to ensure continuity.
  • Act as the voice of the customer within Cloudflare, surfacing product gaps, feature requests, and escalation items to Engineering, Support, and Product.
  • Partner closely with the Account Executive, Solutions Engineer, Customer Success Manager, Delivery Leaders, and other stakeholders to align on account strategy and expansion opportunities.
