Lead Client Growth Manager.

Overview Of The Role

The Lead Client Growth Manager will join our rapidly expanding Performance team in the Americas region — a group at the forefront of innovation within the mobile in-app advertising ecosystem. In a fast-moving and ever-evolving landscape, this team delivers differentiated, high-impact performance solutions powered by market-leading SKAN capabilities, one of the world's largest in-app mobile exchanges, and uniquely advantaged inventory through global telco and OEM partnerships.

The Impact You'll Make

• Own and deepen client relationships with the goal of becoming a top strategic partner, driving maximum campaign ROI by understanding advertiser objectives, KPIs, and operational nuances (technical integrations, creative strategy, supply dynamics, delivery optimizations).
• Lead in-depth campaign analysis and performance reviews; provide consultative, data-driven guidance in weekly and bi-weekly discussions, and confidently drive Quarterly Business Reviews (QBRs).
• Track account-level revenue and delivery priorities on a weekly basis, contributing insights to CXO-level reporting and strategic planning conversations.
• Drive quarterly account retention, revenue, and margin targets, while identifying opportunities for upsell and cross-sell to expand the overall book of business.
• Partner closely with Sales on strategic account planning and execution.
• Collaborate with internal stakeholders (traders, ad operations, and cross-functional partners) to optimize day-to-day campaign performance and implement high-impact strategic improvements.
• Serve as an in-market product expert, partnering with Product and Engineering teams to provide feedback, drive adoption, and elevate AM-region execution standards.

The Experience We Need

• 8+ years of professional experience, including 3–4+ years within the programmatic, demand-side advertising space — ideally in performance or growth marketing environments.
• Proven experience in client-facing roles with a track record of delivering measurable business outcomes.
• Experience working with DSPs and/or MMPs is strongly preferred.
• Strategic mindset with a strong focus on revenue growth and retention; demonstrated success in driving account expansion and long-term client partnerships is highly valued.
• Proficiency with standard business tools, including Salesforce, Microsoft Office Suite, and reporting/visualization platforms such as Power BI and Tableau.
• Able to manage multiple clients and campaigns simultaneously with strong organizational skills, attention to detail, and disciplined time management.
• Comfort collaborating with global teams across time zones and planning work accordingly.
• Bachelor’s degree from an accredited college or university required; background in advertising, marketing, business, or STEM fields is a plus.
