Customer Success Manager III

Customer Success Manager - Enterprise Asia

Why do we have this role?

Sinch is evolving the Customer Success function in Asia to bring it closer to the revenue motion. The Customer Success Manager Enterprise (CSM III) is a hybrid customer success and sales role, responsible for a named portfolio of high value Enterprise Accounts, with a particular focus on customers in the banking and retail sectors.

Building on the traditional CSM remit of customer health, retention, and churn mitigation, the CSM III also carries direct accountability for portfolio growth. This includes owning expansion and upsell targets, leading commercial conversations on plan and pricing reviews, and partnering closely with Account Executives and CS + Sales Leadership to convert whitespace into revenue. The CSM III protects and grows baseline GP within the install base, while ensuring customers continue to realise value from Sinch products and services.

Ultimately, you will combine a consultative, relationship-led approach with commercial rigour to drive both customer satisfaction and portfolio growth.
