We're looking for a strategic, data-driven Senior Finance Manager to partner with our Marketing organization. This role will be the financial lead for media performance, measurement, and ROI and will play a critical role in building a comprehensive, enterprise-wide Cost Per Activation (CPA) framework that pulls together data and costs from multiple business areas.

This leader will own dashboards, reporting foundations, and financial insights that guide high-stakes decisions. The ideal candidate blends strong FP&A experience with hands‑on Power BI and data modeling skills, along with the ability to influence senior leaders and navigate complex cross‑functional environments.

• Serve as the financial lead for media performance, marketing ROI, and investment effectiveness.
• Own the marketing portion of the enterprise CPA framework ensuring accurate cost inputs, consistent definitions, and scalable reporting.
• Partner with leaders across Marketing, Finance, and Operations to align on metrics, assumptions, and strategic decision drivers.

• Lead budgeting, forecasting, and long‑range planning for Marketing, with a focus on media and demand‑generation effectiveness.
• Deliver monthly and quarterly performance reviews including spend analysis, KPI tracking, and insights for executive decision‑making.
• Build and refine business cases for new marketing initiatives and investments.
• Design, build, and maintain Power BI dashboards that consolidate campaign, talent, production, and media data into a unified, digestible view for stakeholders.

• Bachelor's degree in Finance, Accounting, Economics, or related field; MBA or CPA a plus.
• 10+ years experience with 5+ years of experience in financial planning & analysis (FP&A), preferably supporting Marketing.
• Hands‑on experience with Power BI (data modeling, dashboard design) required.
• Advanced Excel and financial modeling skills; experience with ERP and planning tools (e.g., SAP, Oracle).
• Demonstrated ability to build reporting or measurement infrastructure, not just maintain existing tools.
• Strong communication skills; able to translate data‑heavy insights into executive‑ready narratives.
• Proven cross‑functional collaborator in fast‑paced, dynamic environments.

• Comfortable building structure from scratch and creating clarity out of chaos.
• Can operate at both the strategic "what should we measure?" level and the technical "how do we build it?" level.
• Enjoys streamlining manual data sources into polished, scalable dashboards.
• Confident business partner who can influence without authority and drive alignment across teams.
