We are looking for a Customer Success Project Management and Strategy Manager to help our Customer Success organization plan, prioritize and deliver its most important initiatives. You will lead both CS specific and cross-functional projects from start to finish and drive the strategic analysis that shapes the transformation of the team from a customer service focus to a commercial focus.

You will work closely with senior leadership and partner with Sales, Product, Customer Excellence, Finance and Data teams to improve the key levers of NRR growth and customer outcomes.

• Partner with CS Operations and Data teams to keep the CS tech stack (e.g., Salesforce, Gainsight) and reporting aligned with strategy.

• Drive and own change management for new processes and tools, including communications, training and adoption tracking.

• Turn customer and frontline feedback into recommendations for process, product and strategy.

• Act as a trusted partner to senior leaders, translating complex data and project status into clear decisions.
