Desirable

• We’re looking for a Senior / Lead Data Scientist to join Cleo’s Marketing Analytics team (CRM, Organic, Brand)
• You’ll be a primary analytics partner for our organic, brand and CRM functions, building the strategy and measurement foundations for channels including organic social, ASO, SEO and our CRM program
• Your work will directly influence how we grow beyond paid, how we measure the impact of brand and content, and how we use lifecycle communications to drive activation, engagement and retention
• You’ll work day-to-day with organic marketers, brand and PMM, CRM, and growth leadership to uncover insights, improve measurement frameworks, and shape channel and campaign strategy
• This role is for someone who wants to define how Cleo does organic and lifecycle growth at scale, not just report on it
• Paid acquisition has been a core growth engine for Cleo
• To build a more efficient and durable growth model, we’re investing heavily in organic, brand and lifecycle channels
• You’ll be central to that shift – building the measurement, attribution and performance frameworks that increase our organic and owned contribution, make brand investment smarter, and ensure CRM is driving meaningful long-term value, not just near-term clicks
• Analyse performance across SEO, ASO, organic social and other owned/earned channels
• Build foundational measurement frameworks for organic acquisition and content, including clear channel KPIs and diagnostics
• Identify opportunities to grow organic contribution and reduce dependency on paid channels through content, distribution and optimisation
• Partner with Brand and Product Marketing to measure the impact of major product launches and brand campaigns
• Define and track mid-funnel and brand metrics (e.g. awareness, consideration, engagement) and connect them to downstream outcomes using causal methods
• Contribute to cross-channel attribution frameworks that account for both brand and performance activity
• Own the analytics for our email program via Customer.io and other lifecycle touchpoints
• Define and track key CRM and lifecycle metrics across acquisition, activation, engagement and retention
• Partner with CRM and growth teams to design, test and optimise lifecycle journeys and campaigns, including segmentation and targeting
• Design, analyse and iterate on CRM A/B tests, with clear hypotheses, success metrics and learnings that feed back into future campaigns and journey design
• Design, run and interpret experiments across organic, brand and CRM – from content and SEO tests to message and journey experiments
• Conduct cohort and funnel analyses to understand user behaviour from organic entry through to long-term value
• Move beyond reporting to surface strategic insights and clear recommendations on where to invest, what to change and what to stop
• Work with CRM, Brand, Product Marketing and Growth leadership as a thought partner on strategy, roadmaps and investment decisions
• Present insights and recommendations clearly to non-technical stakeholders, turning complex analysis into actionable decisions
• You’ll sit within Cleo’s Data organisation – a 60-person team of Analysts and Data Scientists who partner across product and growth
• You’ll have peers working on experimentation, pricing, lifecycle and product analytics, and a manager who cares about your development through regular feedback, mentoring and dedicated time for learning
• This role is AX3 or AX4 level
