About the role
Hi, I'm Matt Lane, Manager of Account Management at Customer.io, and I'm looking for a Senior Account Manager to join our AMER team. This is a revenue ownership role — you'll manage a portfolio of mid-market and enterprise accounts, driving renewals, identifying expansion opportunities, and building the kind of relationships that make customers want to grow with us. You'll be part of a tight-knit team and a key commercial voice for the accounts you own.
This role is open to candidates based in the UK or Ireland only.
What we value
Commercial ownership — you treat your book of business like it's yours, because it is
Forecasting discipline and data-driven decision-making, not gut feel




Multi-threaded relationships — you build trust across the org, not just with one champion
Expansion through value, not feature gates or mechanical levers
Close partnership with Customer Success — you see CS as a collaborator, not a handoff
What you'll do
Own the full commercial strategy for a portfolio of mid-market and enterprise accounts — renewals, expansion, and churn mitigation
Drive growth by helping customers adopt Customer.io more strategically, identifying new use cases and articulating ROI clearly
Forecast renewal and expansion pipeline accurately with a clear, repeatable methodology
Build multi-threaded relationships from day-to-day operators to Directors and VPs, becoming a trusted commercial advisor
Partner closely with Customer Success on account health and with Sales on expansion deals
Engage Legal and Finance on complex renewals and collaborate cross-functionally to move deals forward
What we're looking for
5+ years
