Senior Meta Media Buyer — Fully Remote — Part-Time

CoTrain is hiring on behalf of Regalstone, a fast-growing e-commerce brand scaling aggressively on Meta with plans to push well into five figures in daily spend. Their new creative team is producing consistently, and ads are ready to launch from day one. This is a chance to get in early and own the account through a major growth phase. They need a senior media buyer who can step in, take ownership, and scale spend profitably with a disciplined bidding strategy.

CoTrain is a vetted marketplace that connects companies with elite, pre-screened talent, so you go straight to real work.

What you’ll own

• Build and manage ABO and CBO campaigns, choosing the right structure for each goal
• Use Cost Caps, Bid Caps, and Highest Volume with clear rationale tied to CAC and growth targets

• Run graveyard campaigns to revive past winners and get more out of proven ads
• Diagnose creative fatigue, attribution issues, and performance bottlenecks, and act on the data
• Give creative strategists and editors clear feedback on what’s working, and keep leadership updated on results
