Senior Manager of Client Success

We are seeking a strategic, execution-driven, and process-obsessed Sr Manager of Client Success to lead and elevate our Client Success team.

Reporting to the SVP of Client Success & Partnerships, this role is responsible for translating high-level Client Success strategy into consistent, measurable execution across the team. While the SVP owns overall Client Success strategy, advancement prioritization, executive engagement, and expansion accountability, this leader ensures operational discipline, strong product adoption, retention performance, and high-quality client engagement across the portfolio.

We are looking for a player-coach who thrives in building process, creating order from ambiguity, and coaching a team to operate with confidence and rigor. You will lead and develop Client Success Managers (CSMs), implement scalable systems, raise execution standards, and personally manage a small portfolio of strategic accounts to model best-in-class performance. You bring structure without rigidity. You build clarity without slowing momentum. Most importantly, you enable your team to feel stronger, more capable, and more empowered over time.

The ideal candidate is both a strong people leader and a rigorous operator who thrives in fast-paced, high-growth environments. If you excel at driving accountability, building scalable frameworks, and elevating team capability, this role offers the opportunity to build and shape a high-performing Client Success team.
