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.

This is not a campaign management role—we're looking for someone who thinks like a growth marketer, owns performance, continuously experiments, and knows how to scale profitable acquisition through Facebook and other paid channels.

You'll work with large advertising budgets, web funnels, creative testing, analytics, and cross-functional teams to drive sustainable growth.

What You'll Do

Plan, launch, optimize, and scale high-volume paid acquisition campaigns.
Manage Meta (Facebook & Instagram) as the primary acquisition channel while exploring and scaling additional traffic sources.
Work with monthly advertising budgets exceeding $200K–300K+.
Build, optimize, and improve web funnels to maximize conversion and profitability.
Analyze every stage of the acquisition funnel and identify opportunities for growth.
Develop and prioritize testing hypotheses across targeting, creatives, landing pages, offers, and funnels.
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.
Collaborate with Product, Design, Analytics, and Development teams to improve conversion rates.
Stay up to date with platform changes, industry trends, and emerging acquisition opportunities.

Requirements

Must Have

4+ years of hands-on experience in performance marketing/media buying.
Extensive experience buying traffic on Meta (Facebook & Instagram).
Experience managing large advertising budgets ($200K+ per month or more).
Strong experience with web funnels (not only mobile app campaigns).
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.
