Role Overview

As Senior Growth Manager for Korea at RZR, you will drive revenue growth and client retention across a portfolio of strategic KR accounts — identifying and executing the highest-impact opportunities through growth initiatives and product adoption.

At the account level, this means building strategic growth plans, managing forecasts and pipelines with discipline, and delivering consultative partnerships across client organizations up to executive level. Internally, it means cultivating strong cross-functional relationships, aligning teams, and removing blockers so that growth strategies land with precision and impact in the KR market.

This is an individual contributor role with real ownership from day one. You will not inherit a playbook — you will build one. The right person for this role combines commercial instincts with analytical rigor, earns trust at every level of a client organization, and operates with the independence and accountability of someone who treats their portfolio like a business.
