Job Description

Responsibilities

Meta ownership across all live markets: Over time, you operate the Meta ad accounts day-to-day across the UK and new markets as they launch. Account structure, campaign builds, audience strategy, bidding, budget pacing, daily optimization - you live in the platform, not above it.
Profit-aware scaling: You push spend up while keeping ROAS / CAC inside target bands. You know when to lean in, when to hold, and when to pull back. You can defend every meaningful spend decision with a clear hypothesis and a clear read.
Multi-geo orchestration: You run multiple country accounts in parallel without dropping balls - different audiences, different creative variants, different compliance requirements, different reporting cuts. You build the systems that make multi-geo manageable.
Creative partnership with André's team: You work hand-in-hand with our Creative Lead to translate platform signal into briefs, run rigorous testing frameworks, and scale winners systematically. You don't just consume creative - you shape what gets made.
Structured operating cadence: You run a weekly rhythm - plan, execute, retro, replan - with reporting that the leadership team can trust without having to ask follow-up questions. Your forecasts are realistic. Your decision rules are explicit. Your communication is crisp.
Account hygiene & resilience: You maintain, harden, and evolve our Business Manager / ad account structures, keeping them resilient against platform volatility, policy changes, and the unique compliance challenges of GLP-1 advertising.
New-channel expansion (over time): As you earn the right, you take on adjacent channels - Google, TikTok, YouTube, programmatic, affiliate - applying the same operator discipline.
Team building (over time): As we add junior buyers underneath you, you hire, mentor, and lead the Meta pod. You build the bench that this hire is the seed of.
