Senior Media Buyer - Meta / Paid Social

We are a fast-growing direct-response ecommerce brand in the health and wellness space, spending significant daily on Meta advertising, with multiple ad accounts across different regions. We are seeking a senior media buying leader to manage and optimize our paid social campaigns, lead a team, and drive profitable growth.

Location: Remote (flexible timezone, overlap with US business hours required)

Responsibilities

• Owning Meta advertising strategy and performance across multiple ad accounts spending six figures daily combined.
• Scaling new ad accounts to high daily spend levels while maintaining stable performance and profitability.
• Managing and mentoring junior media buyers — setting direction, reviewing their work, coaching them to improve.
• Building and maintaining a structured testing system: creative testing, audience testing, primary text variations, placement optimization, and collecting learnings systematically.
• Developing and enforcing scaling rules and guardrails: when to increase spend, when to pull back, and how to stabilize accounts after large creative launches.
• Optimizing for contribution margin / profit, not just ROAS — understanding the relationship between ad spend, acquisition cost, and actual profitability.
• Working closely with the creative strategy team to provide clear feedback on what is working, what is not, and what to test next.
• Managing geo-expansion accounts and developing market-specific strategies for different regions.
• Diagnosing performance issues quickly: understanding when poor results are a creative problem, an audience problem, an account stability problem, or a tracking problem.
• Establishing clear reporting cadences and dashboards so the team and leadership always know where things stand.

Requirements

• 4+ years managing Meta ad accounts at scale ($30K+/day, ideally $50K+/day).
• Direct-response or DTC ecommerce experience — understanding performance marketing, not just brand advertising.
• Managed multiple ad accounts simultaneously and understand the dynamics of account stability, learning phases, and scaling.
• Led or mentored other media buyers and can elevate a team, not just run campaigns yourself.
• Think about profitability and unit economics, not just vanity metrics.
• Data-obsessed and can build a narrative from performance data to drive decisions.
• Experienced with structured testing frameworks and can design experiments that produce clear, actionable learnings.
• Actively use AI tools to improve speed and decision-making.
• Strong communicator who can translate media buying insights into actionable creative briefs.
• Thrive in fast-moving environments and are comfortable with ambiguity and rapid change.
