Job Description:

• Lead advanced paid media performance analysis across platforms including Google Ads, Meta, LinkedIn, TikTok, DV360, Microsoft Ads, Amazon Ads, and other digital channels. 
• Develop measurement frameworks, KPIs, and executive dashboards and reports to evaluate campaign performance and business impact. 
• Conduct attribution analysis (MTA, platform attribution, GA4 attribution) and incrementality testing to quantify true marketing effectiveness. 
• Build and maintain Media Mix Models (MMM) or partner with data science teams to measure cross-channel contribution and optimize budget allocation. (Nice to have) 
• Perform forecasting, projections, scenario modelling, and budget pacing using statistical techniques. 
• Conduct correlation, regression, and trend analysis to identify drivers of campaign performance and customer acquisition. 
• Translate complex analytical findings into actionable recommendations for media strategy, optimization, and investment decisions. 
• Partner with Paid Media, Marketing, Finance, and Analytics teams to support annual planning and quarterly business reviews.
