About Lemon Ads

Lemon Ads is a performance marketing agency helping established and growing DTC e-commerce brands scale through paid media, creative strategy, conversion-rate optimization, email and SMS marketing, influencer marketing, SEO, and data-driven growth strategy.

We manage multiple brands across industries including beauty, fashion, health and wellness, personal care, lifestyle, and home goods.

About the Role

We are looking for an exceptionally experienced Senior Google & PPC Media Buyer to lead the strategy, execution, optimization, and scaling of Google Ads campaigns across a portfolio of DTC e-commerce clients.

This is a highly hands-on position for a senior performance marketer who understands much more than campaign setup and basic optimization. The right candidate must be able to analyze business economics, identify growth opportunities, diagnose performance problems, build sophisticated account structures, and confidently manage substantial advertising budgets.

You will personally manage campaigns while also helping establish best practices, reviewing account strategy, and providing guidance to other team members when needed.

This is not a role for someone who only monitors dashboards, follows automated platform recommendations, or delegates execution. We are looking for a strategic buyer who understands exactly how and why performance changes, knows what action to take and how to scale.

Key Responsibilities

• Develop and execute advanced Google Ads strategies for multiple DTC e-commerce brands.
• Build, manage, optimize, and scale campaigns across:
