Senior Media Buyer (Meta & TikTok) — DTC

Location: Remote, United States
Commitment: Full-time, 9 AM–5 PM
Engagement: Senior independent contractor
Compensation: Fee negotiated based on experience and engagement model
Works directly with: CEO

About Our Client

Our client is a growing US-based direct-to-consumer brand in the travel and commuter accessories space, with a revenue run rate exceeding $10M. The company sells backpacks, carry-on gear and accessories through Shopify and TikTok Shop.

The company is building its internal marketing function, with paid acquisition as one of its key growth pillars. Its primary paid channels are Meta and TikTok.

The Role

You will own hands-on paid acquisition across Meta and TikTok. This is an operator role: you personally manage advertising accounts, make budget and optimization decisions, and turn creative performance data into clear direction for the Creative Strategy Lead.

This is not a people-management position. You are expected to remain directly involved in campaign execution, optimization and performance analysis.

You will work closely with Creative Strategy. They lead concepts, briefs and the cross-channel creative roadmap. You own account structure, delivery, asset-level analysis and testing execution. Together, you review results and decide what to iterate, scale or stop.

Responsibilities

Paid Media Strategy and Account Ownership

• Develop and execute DTC acquisition strategy, campaign architecture and channel allocation across Meta and TikTok.

• Independently make and own campaign and optimization decisions within approved budgets.

Creative Performance Analysis and Testing

• Analyze performance at the individual creative level: hooks, formats, messages, concepts, fatigue, delivery patterns and conversion outcomes.

• Design and execute rigorous creative tests: isolate variables, document hypotheses and results, identify scalable winners.

• Provide specific, evidence-based recommendations to Creative Strategy.

Budget Management and Profitable Scaling

• Allocate and scale spend with discipline against CAC, ROAS, MER, new-customer acquisition and contribution margin.

• Understand how creative quality affects account efficiency and scaling capacity.

Campaign Execution, Diagnosis and Recovery

• Launch and optimize campaigns, bidding, automation, pacing and experiments.

• Diagnose underperformance, including creative fatigue, offer or landing-page issues, tracking limitations and delivery shifts.

• Develop and execute recovery plans, measure outcomes and apply learnings to future campaigns.

Platform Expertise

• Stay current on meaningful changes in Meta and TikTok advertising systems, including Meta Andromeda and evolving automated campaign and creative-delivery capabilities.

• Evaluate the operational impact of these changes, test useful adaptations and explore additional channels when performance data supports expansion.

Requirements

• Personally managed at least $500K per month in DTC/e-commerce paid media spend, directly making budget allocation and optimization decisions. $1M+ per month under direct control is preferred.

• Proven expertise in creative-performance analysis and testing at scale, including asset-level patterns, creative fatigue, diversification, test design and commercial impact.

• Hands-on Meta and TikTok expertise, including current delivery, attribution, bidding and automation systems.

• Practical understanding of Meta Andromeda and the ability to adapt campaign structure, creative testing and optimization strategies to platform changes.

• Demonstrated ability to maintain acceptable acquisition efficiency while scaling, with strong command of CAC, ROAS, MER and contribution margin.

• Documented examples of performance decline, root-cause diagnosis and recovery, including creative-driven interventions.

• Experience translating paid-media findings into actionable creative recommendations while collaborating with a separate creative-strategy owner.

• Independent DTC commercial judgment and repeatable campaign and testing systems.

• Based in the United States.

How Success Is Measured

• Testing quality and throughput: Clear hypotheses, meaningful variations, documented outcomes and evidence-based decisions to iterate, scale or stop.

• Creative contribution: Identifying winners, detecting fatigue, improving the creative mix and connecting asset-level learning to business results.

• Budget ownership and economics: Disciplined allocation and scaling evaluated through CAC, MER, ROAS and contribution margin in context.

• Performance recovery: Timely root-cause diagnosis, decisive corrective action and measurable results.

• Platform mastery: Informed adoption or rejection of meaningful Meta and TikTok changes.

Why This Role

• Own meaningful DTC media investment across Meta and TikTok, with real responsibility for performance decisions at scale.

• Work directly with the CEO and Creative Strategy, turning creative testing and platform insights into commercially effective acquisition.

• Contribute to the development of a growing consumer brand's marketing function.

• Explore new acquisition channels when the evidence supports expansion.
