* Guide clients through their data maturity journey, from unstructured datasets to automation and predictive capability.

Your Skills and Experience
You will be a strong match if you have:
* Deep experience across data engineering, data infrastructure and end‑to‑end platform builds.
* Strong capability in ETL design, data modelling, data normalisation and architecture.
* Confidence working directly with clients in a consultative, solution‑shaping capacity.
* Experience leading or growing technical teams.
* Exposure to AWS, automation tools and orchestrators such as Airflow or Dagster.
* Understanding of machine learning or predictive analytics, even at a conceptual level.
* Experience across multiple industries; familiarity with the music industry is a significant bonus.

What They Offer
