Media Buyer

This is a hands-in-platform individual contributor role. You'll own all paid acquisition across Meta, Google, Snapchat, and TikTok - managing budgets at significant scale across international markets with US being our core market. You're the person building the campaigns, allocating the budget, pulling the levers, and making the calls day to day.

In practice, that means campaign builds, bid strategy, audience segmentation, budget allocation across platforms and markets, and clear performance reporting. It also means working closely with our in-house creative team, you'll be the one translating what the data is telling you into sharp, actionable briefs. What's working, what's fatiguing, what we need to test next. Creative is one of the biggest variables in paid performance, and we treat it that way.

Attribution and measurement are non-negotiable. You'll need a solid grasp of pixel implementation, server-side events and CAPI, UTM architecture, and how to navigate the post-iOS 14 landscape without losing sight of what's actually driving results. We run structured tests constantly - creative, audience, geo, bid strategy - and we expect high testing velocity with clean methodology. If you're the kind of person who gets uncomfortable when a test isn't properly controlled, you'll fit right in.

What We're Looking For

• 3+ years running paid social and paid search at real scale - owning campaigns hands-on, not overseeing others who run them
• Proven experience managing large monthly budgets across Meta, Google, TikTok, and Snapchat
• Strong command of attribution: pixels, server-side tracking, CAPI, and UTMs, built and maintained, not just used
• GA4 proficiency - building reports, analysing funnel behaviour, and connecting ad performance to on-site outcomes
• Full-funnel thinking - you understand how awareness feeds conversion and you don't optimise in isolation
• Experience briefing creative teams from performance data, not gut feel
• Comfortable designing structured tests and drawing clear conclusions from them
• Background in DTC brands or agencies managing comparable budgets

Nice to Have

• Scaled a high-AOV or subscription DTC product profitably
• Driven a fast creative-testing loop with an in-house team
• Comfortable in SQL or BI dashboards beyond GA4
• Experience marketing in beauty, aesthetics, health tech, or appearance-related categories

Why Join

You'll be working with real budgets, across real global markets, with direct visibility of your impact week on week. You'll report directly to the Chief Growth Officer, work alongside a strong in-house creative team, and have genuine autonomy over how the paid acquisition function runs. The scale here is rare for an in-house role - and the feedback loop between your decisions and the business outcomes is short.

Compensation and Logistics

Salary: competitive, base depending on experience, plus performance bonus and pension.

Location: The Library, London - 5 days a week in the office.
