About the Role 

As a Customer Success Manager, you will own a portfolio of merchants and drive the full customer success flywheel: Adopt → Realize Value → Expand → Renew with Confidence This is not a "ticket routing" role. You are a strategic partner in your merchant's growth.

You will bridge the gap between merchant goals and operational reality, ensuring our delivery is both successful and scalable.

Values & Ways of Working

• Extreme Ownership: A "Merchant-First" mentality with a kind-and-caring team orientation.
• Judgment & Precision: Knows when to be strategically bold and when to be operationally precise.
• Scalability: Focuses on building repeatable systems rather than one-off heroics.6

Ideal Candidate Profile 

You are tired of "surface-level" CS roles and want to own the entire lifecycle of a physical product’s journey. You are a systems-thinker who hates "one-off heroics" and would rather build a playbook that solves a problem for 100 merchants at once. You are strategically bold enough to challenge a merchant's assumptions but operationally precise enough to ensure their packages arrive on time.
