This is a hands-on, performance-driven role for someone who lives in Ads Manager and thrives on testing, iteration, and measurable impact.

You’ll be responsible for day-to-day execution, creative iteration, and scaling of paid social campaigns, partnering closely with creative, analytics, and product teams to drive efficient customer acquisition.

What you’ll do

• Build and iterate on full-funnel strategies (prospecting, retargeting, and conversion) to capture and create demand
• Analyze performance data to identify trends, diagnose issues, and unlock growth opportunities
• Improve conversion rates through better ad-to-landing page alignment and funnel optimization
• Partner with analytics to ensure accurate pixel implementation, event tracking, and attribution
• Scale campaigns efficiently while maintaining strict efficiency targets (CPL, CPA, pipeline contribution)
• Develop and maintain a structured experimentation roadmap and share insights across teams
• Stay current on Meta platform changes, betas, and best practices

What success looks like

• Consistent achievement of lead volume and efficiency targets (CPL, CPA)
• Measurable growth in qualified demo requests and direct sign-ups from paid social
• High-velocity creative testing engine that continuously improves performance

• Strong understanding of the role of creative in performance and ability to guide creative direction
• Experience managing and scaling meaningful budgets with efficiency constraints
• Strong analytical skills and comfort translating performance data into action
• Experience with Meta Pixel, Conversion API (CAPI), and attribution frameworks
• Ability to operate as a senior IC with full ownership of strategy and execution
• Strong cross-functional collaboration skills

Nice to Have

• Experience with creative briefing and working closely with in-house or external creative teams
• Exposure to incrementality testing, lift studies, or advanced measurement approaches
