• Monitor pacing and performance throughout the campaign lifecycle, optimise strategically, and step in early to resolve or escalate issues as needed to keep campaigns and partner objectives on track.

• Oversee inventory reservation requests and creative scheduling activities with Technical Ad Operations, using vendor resources appropriately and leading through complex troubleshooting or escalations when needed.

• Collaborate with Sales and other teams to prepare creative performance and insights, drawing broader conclusions and recommendations for strategic agency accounts and non-endemic advertiser verticals.

• Lead client and agency calls to review creative strategy, production timelines, campaign performance, and next steps, representing the team with confidence and sound judgement.

• Build trusted relationships across media agency networks, including agency leadership, planning, activation, investment, and operations stakeholders.

• Support upsell and cross-sell initiatives through partner education, sharing relevant insights, reports, new product opportunities, and case studies from comparable clients or verticals.

• Coordinate relevant case studies, reports, workshops, and best-practice materials that help agencies and clients understand and adopt EGA solutions.

• Mentor teammates and serve as a go-to resource for peers on complex campaigns, partner issues, agency ways of working, and best practices.

• Lead team and cross-functional improvement efforts that strengthen campaign execution, partner service, and operational efficiency, bringing together input from across regions and team levels before forming recommendations.

• Support the manager with business metrics, reporting, creative approvals, policy exceptions, and higher-order problem solving as needed.

Experience and Qualifications;

• Bachelor's or Master's degree, or equivalent experience.

• 5+ years of relevant experience in a media-related role within an agency, client, or advertising team.

• Proven experience working directly with media agencies, agency groups, or holding companies across multiple advertiser verticals and client categories.

• Experience with campaign and workflow tools such as Salesforce, Jira, Google Ad Manager, Tableau, or comparable ad-tech platforms is preferred; ability to operate as a power user of relevant campaign tools is strongly valued.

• Growth mindset, sound judgement, and the ability to mentor more junior colleagues, develop them through workstream ownership opportunities, and help improve team processes and outcomes.
