Customer Success Manager
About Tidal Cyber
Tidal Cyber is redefining how organizations approach cybersecurity. We pioneered Threat-Led Defense, helping security teams understand what threats matter most, how well they’re covered, and where to focus next.
Founded in 2022 by MITRE veterans, we’ve quickly moved from bold idea to rapid adoption. With Series A funding secured and strong market momentum, we’re scaling fast and Customer Success is at the center of that growth.
If you thrive in high-ownership environments, love building while executing, and want to shape the future of Customer Success at a breakout cybersecurity company, this role is for you.
About the Opportunity

You’ll partner with security leaders, drive adoption of Threat-Led Defense programs, influence product direction, and directly impact retention and expansion. You’ll help define what Customer Success looks like as we scale.
