Full Description

We’re partnering with a high-growth, venture-backed startup using AI and data to reshape a massive, traditionally offline industry.

They’re hiring a Growth / Marketing Data Scientist to work directly with leadership and own the insight layer behind growth.

This is not a reporting role. It’s about driving decisions, influencing spend, and proving what actually works.

What you’ll do:

* Own growth and marketing analytics end-to-end

* Analyse the full funnel: lead → conversion → revenue

* Evaluate performance across paid channels (Google, Meta, etc.)

* Build and iterate on LTV / CAC models

* Run segmentation, cohort analysis, and experiments

* Identify high-performing channels, campaigns, and audiences

* Turn data into clear, actionable insight for leadership

This role is about impact, not dashboards.

What they’re looking for:

* Background in Growth / Marketing Data Science or Analytics

* Strong SQL + solid Python

* Experience working with marketing or growth teams

* Hands-on exposure to paid acquisition channels

* Deep understanding of:

* Funnel analysis

* Attribution

* Segmentation

* LTV / CAC

* Experience running A/B tests / experiments

* Ability to influence non-technical stakeholders

Nice to have:

* Experience with Google Ads, Meta Ads, TikTok Ads

* Tools like Mixpanel, Amplitude, PostHog

* Background in high-growth startups or PLG environments

What this isn’t:

* Not a pure ML / research role

* Not a BI / reporting role

* Not a data engineering role

Why it’s interesting:

* Direct impact on how growth budget is deployed

* Work closely with leadership on real business decisions

* Join a company scaling quickly, with strong traction

If this sounds interesting, drop me a message - happy to share more context.
