About Media Stack
Media Stack is a network of ecommerce specialists with 50+ years of combined experience across paid media, creative strategy, and CRO. We work with ambitious consumer brands across fashion, beauty, and wellness, and we're building a team of people who take genuine ownership over their work and care about the results as much as our clients do.
The Role
We're looking for a Senior Media Buyer to take the lead across a number of paid social accounts at Media Stack. This is a full-time, remote role for someone who is as comfortable in the data as they are in a client call — and is able to lead and craft the creative strategy.
You'll be managing and scaling campaigns across Meta and TikTok for a portfolio of ecommerce clients, working closely with our in-house Creative Strategist, and helping shape how the paid media function operates at the agency. This is a leadership role as much as an execution role.
What You'll Be Doing
- Planning, executing, and optimising paid social campaigns across Meta, TikTok, and other paid social channels
- Collaborating closely with our in-house Creative Strategist — you'll be the key performance input, feeding data-driven insights into the creative process to inform what gets made and tested next
- Leading on creative strategy from a performance perspective — analysing what's working, identifying winning angles, and briefing creative on hooks, formats, and messaging
- Owning client relationships directly — communicating performance clearly, proactively flagging issues, and building trust
- Forecasting, budget pacing, and reallocation across accounts to maximise performance
- Setting up and interpreting A/B tests across creatives, audiences, and bidding strategies
- Applying attribution modelling knowledge to reporting and client-facing analysis
- Contributing to how the paid media department is built and run

- Proven track record with ecommerce consumer brands — fashion, beauty, and/or wellness
- Strong analytical ability — attribution modelling, ROAS, CAC, funnel dynamics
- A genuine creative strategist — you understand why an ad works, not just whether it does
- Direct client-facing experience — you're transparent, articulate, and proactive
- Someone entrepreneurial — if you've run your own venture at some point, even better
- Advanced in Excel or Google Sheets for reporting and analysis
- Familiarity with Motion (creative strategy tool) — not a hard requirement, but a strong preference
- Comfortable working independently in a remote environment
- Agency experience is a strong plus; brand-side experience also valued
- Someone that is always looking to improve process efficiencies.
- AI native to support with work.
