Senior Performance Marketing Manager

Responsibilities

• Own all aspects of our performance marketing: campaign strategy, implementation, optimisation, and analysis
• Set channel strategy and manage budgets across all digital channels, optimising for CAC:LTV and payback rather than chasing surface metrics
• Run a structured testing programme across creative, bidding, audiences, and channel mix, using data-driven insights to continually test, measure, and optimise spend
• Measure real impact, not just platform-reported numbers. You'll judge performance on cohort behaviour, repeat GMV, contribution margin, and incrementality
• Collaborate with content creators and designers to produce high-converting ad creative and landing pages
• Conduct keyword research, ad copywriting, and A/B testing to sharpen campaign effectiveness
• Report on performance to senior leadership with clear, actionable recommendations

Requirements

• A track record running large Google Ads accounts at scale. This is the hard requirement
• Genuine breadth across the digital mix. You understand paid social, organic, and how channels compound, and you're not a one-channel specialist
• A real appetite for both sides of the job: you enjoy creative strategy, ad production, and script writing as much as you enjoy living in the data
• Excellent understanding of conversion rate optimisation (CRO) principles and tactics
• Comfort with incrementality testing (geo hold-outs, lift studies) and the instinct to question what attribution tells you
• Hands-on experience implementing tracking, including tag management and server-side setups (e.g. GTM), and debugging dataLayer and signal issues yourself
• Strong analytical chops. You work in the data, think in CAC:LTV and payback, and ideally know your way around SQL or a BI tool
• You stay on top of the latest in digital marketing and get genuinely excited by new tools and tactics. You're especially keen on what AI can do and can't wait to automate the repetitive parts of the job
• The judgement to operate in a fast-moving environment and prioritise what actually moves the needle

Preferred

• SEO or other organic and owned-channel experience
• B2B, marketplace, or ecommerce background
• You enjoy writing, whether that's ad copy, briefs, or making the case to stakeholders

• 26 days of annual leave, plus 4 additional personal days
• Company performance-based bonus
• Attractive equity package
• Pension contributions
• Annual learning & development budget
• Office-led culture with hybrid flexibility
• Dog-friendly offices
