The Role

The Paid Media Manager owns full-funnel media performance for a portfolio of Third clients across TikTok Shop (Product GMV Max and GMV Max LIVE), TikTok Ads, Meta, Google Search and YouTube. You’ll manage accounts end to end: media strategy, account architecture, campaign builds, budget allocation and pacing, in-platform optimization, and performance reporting.

Our book spans single-brand TikTok Shop launches through multi-brand, cross-channel programs optimized to GMV, ROAS, CAC and 30-day revenue. This is a hands-on, in-platform role for someone who can also translate performance into clear recommendations for clients.

What You’ll Do

Media strategy and account setup

• Run account audits covering pixel/CAPI and event tracking, UTM taxonomy, catalog health and account structure before launch.
• Build channel-level media plans with clear budget splits, KPIs and benchmarks tied to client business goals.
• Plan launch flighting and test-and-learn phases from launch through scale.

TikTok Shop and GMV Max

• Build and manage Product GMV Max and GMV Max LIVE campaigns, including hero-SKU selection, ROI targets and SKU-level budget reallocation.
• Run pre-heat, engagement and awareness campaigns flighted around LIVE sessions to drive live-room traffic.
• Report GMV Max performance on GMV, ROI, SKU and campaign efficiency, LIVE and promo results, without overstating paid vs. organic attribution.

Meta, Google Search and YouTube

• Balance broad and Advantage+ delivery with structured audience testing: 1P customer lists, custom audiences, lookalikes, retargeting, interest stacks and engagers.
• Manage Search with branded and non-brand campaigns segmented, keyword and search-term management, and bid strategy optimization.
• Run YouTube for mid-funnel consideration using custom intent and in-market audience signals with action-oriented video formats.

Optimization and budget management

• Daily: pacing, bids and bid strategies, budgets, search terms, audience signals and delivery anomalies.
• Weekly: KPI performance vs. benchmark, test reads, creative performance trends and budget shifts.
• Monthly: performance to goal, spend reallocation and scale recommendations.
• Own budget pacing to plan across channels, campaigns and SKUs.

Creative testing and insights

• Partner with Performance Creative on the creative testing roadmap: surface top performers, flag creative fatigue and recommend new concepts and iterations.
• Evaluate creative on attention and efficiency metrics (hook rate, hold rate, 6-second views, watch time, CTR, CPM).

Reporting and client communication

• Deliver weekly performance reporting with KPIs vs. benchmark, key insights and next actions.
• Maintain live client dashboards covering spend, content and creator spend, platform-level results and recommendations.
• Build LIVE scorecards per session (views, view duration, follows, orders, GMV, ROI, change vs. prior LIVE).
• Lead weekly client calls and contribute media strategy, KPI and roadmap slides for pitches and QBRs.
