As a Project Manager, you will be responsible for end-to-end project delivery, including planning, execution, client communication, and cross-functional coordination. You will play a key role in ensuring both marketing performance and operational excellence across teams.

This role goes beyond traditional project management. You will operate across advertising, CRO, content, and localization, ensuring that all work is aligned toward measurable business outcomes.
