Freelance Marketing Data Engineer
£450 p.d Outside IR35 | 1x day on-site, London | 2 months | ASAP start

💁‍♀️ Open to part-time & full time work for this project

Looking for someone who genuinely lives and breathes marketing data.

I'm working with an agency client who needs a freelancer for an initial 2-month contract (with a strong chance of extension), supporting the development of their marketing data infrastructure and analytics capability.

This isn't a reporting or dashboard-only role.

We're looking for someone who understands how marketing data is collected, transformed, tested and modelled before it reaches the reporting layer.

You'll be comfortable working with data pipelines and modern analytics stacks, as well as translating complex marketing data into meaningful commercial insight.

You'll ideally have experience with:
👉 SQL
👉GA4
👉dbt
👉Airbyte (or similar ELT tools)
👉Marketing data modelling
👉Building and maintaining reliable data pipelines
👉Data quality testing and validation
👉Attribution and marketing measurement
👉Marketing Mix Modelling (MMM) or an understanding of statistical marketing measurement approaches
👉Looker Studio, Power BI or similar BI tools

We're looking for someone who can confidently explain not just which tools they've used, but why they've used them, how they fit together, and the technical thinking behind the solutions they've built.
