Senior Facebook Media Buyer — Fully Remote

About this role
CoTrain is hiring on behalf of a brand spending ~$100k+/month on Meta and looking to push significantly higher. They need an A-player Meta buyer who can take ownership of the account immediately and scale hard. CoTrain is a vetted marketplace that connects companies with elite, pre-screened talent, so you go straight to real work.
This is not a role for someone who needs 3–4 weeks to "learn the account" before making moves, or who just launches campaigns, follows Meta's recommendations, and checks ROAS once a day. Meta is your primary domain, and you handle media buying A–Z without hand-holding. You're not starting from zero — spend is already flowing, and you need to come in, read what's happening, and move from day one.
What you'll own
Own Meta performance end to end and scale aggressively — horizontally and vertically — while protecting efficiency
Run modern Meta buying fluently: CBO structures, efficient ABO creative testing, ASC/Advantage+, bid caps and cost controls, campaign consolidation, and budget allocation
Keep Ads Manager clean and structured — clear naming and campaign logic so anyone can see what's testing, scaling, fatigued, being recycled, or ready to kill
Manage graveyard and evergreen/winner campaigns properly, knowing when to recycle winners and when older creatives deserve another shot
Run whitelisting/partnership ads and buy across multiple pages, with sound retargeting and funnel segmentation
Recognize when the account can take more spend and act fast, moving winners into proper scaling structures
Drive the creative feedback loop
This is a major part of the role — you don't just wait for the strategist to hand you ads. You create an active loop between media buying, creative, and ownership, telling the team what the account is saying:
Which hooks, angles, formats, creators, and offers are winning or fatiguing
What deserves iteration, more volume, or a kill
What's missing — new advertorials, landing pages, offers, whitelisting pages, UGC creators, static concepts, hook variations, MOF/BOF creative, or a new funnel to test
Your feedback should be actionable enough that the strategist can turn it straight into briefs — you help drive the creative roadmap off real account data.
You need to know the numbers
You understand every key Meta metric and, more importantly, why it's moving and what to do about it: CPM, CPC, CTR, CPA, CVR, ROAS, MER, frequency, hook rate, hold rate, thumb-stop rate, LP conversion rate, AOV, and contribution margin.
Communication
Regular (daily or every-other-day) breakdowns: spend, winning/losing campaigns, ads starting to scale, creative fatigue, emerging hooks and angles, testing results, scaling decisions, account problems, and what the creative team needs next. We don't want someone who disappears into Ads Manager and only talks when asked.
Bonus experience
Meta is the priority, but experience across TikTok, Snapchat, Taboola, Outbrain, AppLovin, Google, YouTube, or native platforms is a strong plus.
Compensation
$2,000–$3,500/month + performance bonuses, based on experience. Fully remote, long-term (6+ months), scaling an account already doing $100k+/month.
How to apply
Apply through CoTrain, not by email — open the listing on CoTrain, sign in or create your expert profile if you're new, and submit with your relevant experience — monthly and largest spend managed, brands you've scaled, and case studies or screenshots of scaling results — plus a short note on why you're the one. You'll also take a short 8-minute interview as part of your application. From there you'll get vetted and matched through the platform, and we'll reach out to you on CoTrain.
PS: We review applications daily — make sure you complete your 8-minute interview to be considered.
