About The Role
We’re looking for a Senior / Lead Data Scientist to join Cleo’s Marketing Analytics team (Organic + Brand).
You’ll be a primary analytics partner for our organic and brand functions, building the strategy and measurement foundations for channels including organic social, ASO, SEO, GEO, plus brand marketing. Your work will directly influence how we grow beyond paid, how we measure the impact of brand and content.
You’ll work day-to-day with organic marketers, brand and PMM 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 brand-led growth at scale.
Why this role matters
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 and brand 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. SEO measurement at Cleo is close to greenfield – you’ll build it from the ground up. You’ll also define how we measure the emerging channel of Generative Engine Optimisation (GEO) – visibility within ChatGPT, Claude and Google AI Overviews.
What you'll be doing
Organic & owned channel analytics
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. Build Cleo’s SEO measurement – the KPIs, attribution and diagnostics for organic search. Establish how we measure and grow visibility in GEO – a channel we want to lead on.
Brand measurement
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. Work to demonstrate the incrementality of brand marketing efforts.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Experimentation & insights
Design, run and interpret experiments across organic and brand – from content and SEO tests to brand marketing geo-lift/regional holdout 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.
Cross-functional collaboration
Work with Organic marketers, 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.
The team you'll join
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 marketing analytics, and a manager who cares about your development through regular feedback, mentoring and dedicated time for learning.
What we're looking for
3+ years’ experience in marketing or growth analytics, with significant time spent on organic and/or brand channels for B2C or subscription products, with hands-on organic experience preferred. Strong SQL skills; comfortable exploring, transforming and validating large datasets independently. Hands-on analytics experience with organic or owned channels (e.g. SEO/ASO, organic social, content). Exposure to brand or upper-funnel measurement is a strong plus. Practical experience with experimentation (e.g. A/B tests, holdouts, geo-lift or SEO tests) and interpreting results for non-technical stakeholders. Experience with funnel and cohort analysis, and comfort working with mid-funnel metrics (engagement, consideration, intent) as well as revenue outcomes. Strong commercial judgement: able to connect organic and brand metrics to acquisition efficiency, retention, LTV and profitability. Ability to communicate complex analysis simply, with clear narratives and recommendations.
Nice to have
Hands-on experience with SEO/ASO analytics (e.g. search console, keyword analysis, store listing optimisation) or social/content analytics. Python or R for more advanced analysis, experimentation or modelling. Understanding of brand measurement (e.g. brand lift studies, brand tracking, survey-based measurement, causal inference). Experience shifting acquisition mix from paid to organic/owned or building new organic/brand programs from scratch. Experience in consumer fintech, high-growth consumer apps or subscription products. Awareness of Generative Engine Optimisation (GEO) and how it can be measured or a genuine appetite to pioneer it.
