Our platform combines data intelligence, marketing automation, and conversational AI to help businesses engage smarter, move faster, and scale effortlessly.

This is a builder role for someone who thrives in early-stage environments and enjoys designing scalable systems that drive measurable revenue impact.

As Senior Manager, Scaled Customer Success, you will own the strategy, operating model, and performance of Fello’s digital Customer Success engine for a rapidly expanding base of SMB and mid-market customers. You’ll design and scale the programs, lifecycle infrastructure, and team that allow Fello to deliver customer value efficiently - across hundreds of accounts - without sacrificing outcomes.

Establish lifecycle programs across onboarding, adoption, renewal readiness, and expansion that drive measurable retention and revenue impact.

Use customer data and experimentation to improve performance over time.
