Marketing Data Scientist

Marketing Data Scientist

Salary: Up to £65k

Location: London (hybrid)

We’re working with a fast-growing, data-led consultancy that sits at the intersection of data science, marketing, and commercial strategy.

What you’ll be doing:

• You’ll work closely with marketing and performance teams, using messy, real-world datasets (think Meta, Google, CDPs) to uncover insights, design experiments, and build models that directly influence business decisions.
• This is a hands-on role where you’ll own problems end-to-end, from data exploration and cleaning through to modelling, experimentation, and presenting insights to stakeholders.

What they’re looking for:

• Strong SQL & Python skills, ideally within cloud environments (GCP, AWS, Databricks)
• Experience building or applying models such as LTV, churn, propensity, MMM or forecasting
• Exposure to experimentation (A/B testing, incrementality, Bayesian methods, causal inference)
• Ability to work with messy data and turn it into clear, actionable insights
• Strong communication skills and confidence working with non-technical stakeholders

Nice to have:

• Experience with tools like dbt, Airflow, GA4
• Exposure to attribution modelling or performance marketing
• Interest in applying AI/ML within data workflows

If you’re someone who enjoys solving ambiguous problems, working with real-world data, and wants to build a strong foundation in marketing-focused data science, this could be a great next step.
