About the Role

We're looking for a highly experienced Senior Media Buyer to join our performance marketing team and scale subscription-based products across Tier-1 markets.

• Drive continuous creative testing, working closely with designers and creative strategists.
• Monitor key performance metrics including CPA, ROAS, CAC, LTV, Trial Rate, Purchase Rate, and overall funnel efficiency.
• Use analytics to make data-driven optimization decisions rather than relying on intuition.

• Deep understanding of the complete customer acquisition funnel.
• Proven experience designing and running structured A/B tests.
• Strong analytical mindset with the ability to turn data into actionable insights.
• Experience working with attribution and analytics platforms (GA4, AppsFlyer, Mixpanel, Amplitude, or similar).
• Strong understanding of conversion rate optimization (CRO).
• Experience working closely with creative production and performance creatives.
• Ability to independently generate, validate, and prioritize growth hypotheses.
• Advanced knowledge of campaign optimization, audience strategy, bidding models, and scaling techniques.
• Strong understanding of AI-powered workflows and the ability to leverage AI to improve campaign performance, accelerate research, generate testing hypotheses, optimize creatives, and automate repetitive marketing tasks.
• Hands-on experience using AI tools (such as ChatGPT, Claude, Gemini, Cursor, or similar) as part of the daily media buying workflow.
• Experience building or using marketing automations with AI and no-code/low-code tools to improve operational efficiency.
• Strong ownership mindset with the ability to independently identify growth opportunities, prioritize experiments, and take full ownership of acquisition performance.
   

Nice to Have

• Experience with additional paid acquisition channels (Google Ads, Native, TikTok, DSPs, Apple Search Ads, etc.).
• Experience promoting subscription-based or SaaS products.
• Experience in iOS/mobile app marketing.
• Familiarity with SKAN, MMPs, and privacy-focused attribution.
• SQL or advanced spreadsheet skills.
• Experience with BI tools such as Tableau, Looker Studio, or Power BI.
• Experience building automations using tools such as n8n, Make, Zapier, or similar platforms.
• Basic understanding of APIs and AI-assisted workflow automation.
   

What Success Looks Like

• Profitably scales paid acquisition across multiple channels.
• Continuously launches new experiments across audiences, creatives, funnels, and offers.
• Improves funnel conversion rates through data-driven optimization.
• Proactively identifies growth opportunities and new acquisition strategies.
• Uses AI and automation to increase productivity, accelerate experimentation, and improve campaign performance.
• Makes decisions based on analytics rather than assumptions.
• Collaborates effectively with Product, Design, Analytics, and Development teams to drive business growth.
