Senior / Lead Data Scientist, Marketing Analytics (CRM, Organic, Brand)

Join to apply for the Lead Marketing Analyst (CRM, Organic, Brand) role at Cleo.

About Cleo

At Cleo, we’re not just building another fintech app. We’re embarking on a mission to fundamentally change humanity’s relationship with money. Imagine a world where everyone, regardless of background or income, has access to a hyper‑intelligent financial advisor in their pocket. That’s the future we’re creating. Cleo is a rare success story: a profitable, fast‑growing unicorn with over $200 million in ARR and growing over 2× year‑over‑year. It’s a chance to join a team of brilliant, driven individuals passionate about making a real difference. We have an exceptionally high bar for talent, seeking individuals who are not only at the top of their field but also embody our culture of collaboration and positive impact.

About the Role

We’re looking for a Senior Marketing Analyst (Organic, Brand, CRM) to join Cleo’s Marketing Analytics team. You’ll be a primary analytics partner for our organic, brand and CRM functions, building 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, measure the impact of brand and content, and 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.

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, 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.

What You’ll Be Doing

• Organic & Owned Channel Analytics: Analyze 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 optimization.
• Brand & Product Launch 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.
• CRM & Lifecycle Analytics: 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 optimize lifecycle journeys and campaigns, including segmentation and targeting. Design, analyze and iterate on CRM A/B tests, with clear hypotheses, success metrics and learnings that feed back into future campaigns and journey design.
• Experimentation & Insights: 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.
• Cross‑Functional Collaboration: 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.

The Team You’ll Join

You’ll sit within Cleo’s Data organization – 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.

What We’re Looking For

• 3+ years’ experience in marketing or growth analytics, with significant time spent on organic, brand and/or CRM/lifecycle channels for B2C or subscription products.
• 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) and/or CRM/email programs.
• Practical experience with experimentation (e.g. A/B tests, holdouts, brand or CRM 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, brand and CRM metrics to acquisition efficiency, retention, LTV and profitability.
• Ability to communicate complex analysis simply, with clear narratives and recommendations.

Nice to Have

• Python or R for more advanced analysis, experimentation or modeling.
• Hands‑on experience with SEO/ASO analytics (e.g. search console, keyword analysis, store listing optimization) or social/content analytics.
• Experience with CRM tools such as Customer.io, Braze, Iterable or similar, including segmentation and lifecycle experimentation.
• 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.

What You Get for Your Hard Work

• A competitive compensation package (base + equity) with bi‑annual reviews, aligned to our quarterly OKR planning cycles.
• Work at one of the fastest‑growing tech startups, backed by top VC firms, Balderton & EQT Ventures.
• A clear progression plan. We want you to keep growing. That means trying new things, leading others, challenging the status quo and owning your impact. Always with our complete support.
• Flexibility. We can’t fight for the world’s financial health if we’re not healthy ourselves. We work with everyone to make sure they have the balance they need to do their best work.
• Work where you work best. We’re a globally distributed team. If you live in London we have a hybrid approach, we’d love you to spend one day a week or more in our beautiful office. If you’re outside of London, we’ll encourage you to spend a couple of days with us a few times per year. And we’ll cover your travel costs, naturally.

Other Benefits

• Company‑wide performance reviews every 6 months.
• Generous pay increases for high‑performing team members.
• Equity top‑ups for team members getting promoted.
• 25 days annual leave a year + public holidays (+ an additional day for every year you spend at Cleo, up to 30 days).
• 6% employer‑matched pension in the UK.
• Private Medical Insurance via Vitality, dental cover, and life assurance.
• Enhanced parental leave.
• 1 month paid sabbatical after 4 years at Cleo.
