About The Position

Onescreen is hiring an experienced Senior OOH Media Planner to own the strategy and execution of out-of-home campaigns across clients and verticals.

The planner works independently, collaborates with account executives, account managers, creative teams, clients, senior decision makers, and Product, and contributes to stronger planning processes and best practices.

Success includes owning active campaigns, negotiating with vendors, presenting plans, identifying workflow and platform friction, and mentoring junior team members.
