Senior Media Buyer

Summary

Who we are
A performance marketing agency that operates as an embedded growth team for our clients. We manage 5+ active accounts across DTC e-commerce, mobile apps (iOS/Android), and lead generation verticals with a combined monthly spend of $200k+. Our primary platform is Meta, with TikTok and Google Ads for select accounts.
We’re a small, senior team - no layers, no bureaucracy. You’ll work directly with the founder (strategy), a creative lead (production), and a PM (coordination). Decisions happen fast, and you’ll have real ownership over the numbers.

The role
You’ll own the full performance lifecycle across multiple accounts - from campaign architecture and bid strategy to creative testing orchestration, anomaly response, and weekly client reporting.
You’ll think in unit economics (CAC, payback period, LTV), plan 1-3 months ahead, and work closely with our creative lead to turn performance data into actionable briefs. When ROAS drops 30% on a Tuesday morning, you’re the one who diagnoses whether it’s creative fatigue, audience saturation, or a platform delivery bug - and you fix it before anyone needs to ask.

What you’ll own

Creative analysis and guidance
Analyze creative performance using hook rate, hold rate, CTR, CVR, CPA, and ROAS to identify winners, fatiguing assets, and patterns worth iterating on
Translate data into specific, actionable briefs for the creative team: what formats to build (video, static, carousel, UGC), what angles to test, what volumes are needed, and what the priority order is
Define test mix and cadence - you decide what gets launched, how much budget it gets, and when to kill or scale
QA all creatives before launch: copy accuracy, size compliance, ad platform policy, landing page alignment

Tracking and measurement
Implement and maintain tracking: Pixel, CAPI, AEM, UTMs, GA4/GTM
For mobile app clients: configure and verify MMP (Mobile Measurement Partner) attribution, set up in-app event tracking, manage postback configurations, and ensure accurate install/purchase/subscription attribution across iOS and Android
