Media Buyer Senior, Performance & Growth

Media Buyer Senior, Performance & Growth at M.L.O Growth

Are you the Senior Media Buyer we are looking for? At M.L.O Growth, we help eCommerce brands scale to 6-7 figures monthly by combining Paid Media, Creative Strategy, and Retention.

We are looking for a Senior Media Buyer specialized in Meta Ads and Google Ads to collaborate on a freelance basis with our team. We are seeking someone proactive, performance-oriented, and with a strategic mindset, capable of managing and scaling eCommerce accounts autonomously. This is not a traditional agency role with bureaucracy and slow hierarchies. Here, you will have real autonomy, quick decisions, and a total focus on results.

About M.L.O Growth

M.L.O Growth is a boutique agency specializing in eCommerce growth. We work with ambitious DTC brands in sectors such as Beauty, Wellness, Supplements, and Home. Our objective is to scale brands to 6 and 7 figures monthly through our proprietary system that combines Paid Media (Meta, Google, TikTok), Creative Strategy, and Creative Production. Our clients are fast-growing brands, and we work as growth partners, integrating into their teams.

Our Values

• Extreme Ownership: You assume total responsibility for results.
• Excellence in Execution: How you do one thing is how you do everything.
• Curiosity and Experimentation: We are always testing, learning, and iterating.
• Real Client Impact: We only win when our clients win.
• Growth Mindset: This industry changes fast, and so do we.

Requirements

• 2–4+ years of experience managing Meta Ads for eCommerce.
• Experience managing accounts with 50K–200K€+ in monthly spend.

Responsibilities

• Create, optimize, and scale campaigns in Meta Ads and Google Ads.
• Manage TikTok Ads campaigns when part of the account strategy.
• Design and maintain efficient testing structures (audiences, creatives, offers).
• Analyze results and generate actionable insights (not just report metrics).
• Work alongside the Creative Strategist to launch new concepts and variations.
• Detect scaling and funnel optimization opportunities.
• Ensure robust tracking (Pixel, CAPI, Tag Manager, GA4).

What We Value Especially

We like profiles that:

• Propose improvements without being asked.

• Are comfortable working with AI and modern tools.
• Enjoy iterating and learning from data.
