Responsibilities

• Own and grow a portfolio of direct clients and agencies across diverse verticals, with clear accountability for revenue expansion, retention, and relationship health.

• Identify and activate growth opportunities: anticipate client needs, propose upsell/cross-sell solutions, and leverage Smadex capabilities to expand spend.
• Serve as the voice of the client internally: escalate blockers early, collaborate with Sales, AdOps, Product, and GCE teams, and ensure smooth execution across workflows.
• Produce and present strategic reviews including QBRs, wrap-ups, and post-mortems with clear recommendations and data-driven insights.
• Manage monthly billing and reconciliation including spend confirmations, dispute resolution, and revenue forecasting hygiene.
• Represent Smadex externally: travel for client meetings and industry events to strengthen partnerships and unlock new opportunities.

Requirements
