Job description

• We’re looking for a Growth Marketing Manager to take ownership of paid media across three core channels for a fast-growing consumer brand. You won’t just execute someone else’s strategy — you’ll shape how it’s run
• You’ll take over hands‑on management of our Meta, Google (Search, PMax and Demand Gen) and Amazon accounts, with a direct line into growth strategy alongside our Senior Growth Marketing Manager and visibility across our UK, US, EU and rest‑of‐world markets. You’ll own reporting across these channels, identify and implement optimisation opportunities, and turn performance data into clear recommendations senior stakeholders can act on
• You’ll also step straight into people management, mentoring our Junior Growth Executive, with room to build a bigger team as we grow. There’s real scope to shape how our paid‑media function develops, and a clear path into more senior responsibility
• Own execution across Meta, Google (Search, PMax and Demand Gen) and Amazon: campaign builds, launches and day‑to‑day management
• Plan and deliver campaign activity for new product launches and sale events, working closely with the Senior Growth Marketing Manager on strategy and channel approach
• Manage, mentor and train our Junior Growth Executive, with scope to grow the team further as we expand
• Own reporting across these channels, tracking performance and communicating clear, actionable updates to senior stakeholders
• Identify and implement optimisation opportunities across campaigns, audiences, bidding and creative
• Support budget allocation and pacing across channels to hit ROAS targets as spend scales
• Plan and run A/B tests across ad creative, copy and landing pages, working closely with our Creative and Web/Ecom teams
• Analyse key metrics (ROAS, CPA, CVR, AOV, CAC) and turn insight into action
• How will success be measured?
• Full ownership of Meta, Google (Search, PMax, Demand Gen) and Amazon within your first quarter, with no dip in performance through the handover
• Mentoring and managing the Junior Growth Executive
• A reporting cadence senior stakeholders can rely on
• Our Junior Growth Executive mentored to the point they’re running day‑to‑day activity independently, freeing you up for more strategy and testing

Benefits

• Flexible hybrid working

• Charlie HR perks package including discounts on hundreds of high street brands and services
• Cycle to Work Scheme
• Employee Pension Scheme

• Proven experience building and optimising campaigns end to end
• Experience analysing performance metrics (ROAS, CPA, CVR, AOV, CAC) and turning them into clear recommendations
• 2–4 years’ hands‑on experience running paid media campaigns across Meta and Google (Search, PMax and Demand Gen); Amazon Advertising experience preferred but not essential
• Strong Excel/Google Sheets skills; Power BI or similar reporting tool experience is a plus
• Comfortable taking ownership at pace
• Adaptable and resilient, able to manage performance across multiple markets at once, each with its own customer behaviour and currency
• Solutions-focused, and comfortable making decisions without being told to
• A clear communicator who can flex between coaching a junior exec day‑to‑day and updating senior stakeholders with equal clarity
• Ambitious and driven, motivated by the chance to build ownership and grow into more senior responsibility
• Amazon Advertising experience
• Shopify & GA4 experience
• Power BI or similar reporting tool experience
• Prior experience formally managing or mentoring someone junior
