Why this job is important
We’re currently undergoing the largest technology transformation our $4bn business has ever seen. As a cloud‑native organisation (Azure), we’re modernising and integrating our platforms to respond faster, smarter and at greater scale.
A critical part of this transformation is Digital Twins — a bold, experimental platform that simulates consumer behaviour at scale, enabling Kantar's products to test scenarios and predict outcomes before they happen.
As a Senior Data Engineer, you’ll join a very small, agile, start‑up‑style team building it from the ground up. You’ll move fast, test ideas quickly, learn from setbacks and iterate. It’s a demanding challenge, led by industry experts, where your thinking and engineering choices will directly shape the outcome.

-
Designing and building robust data pipelines, platforms and databases that support AI‑driven products
-
Collaborating closely with engineers, data scientists and product partners to shape how Digital Twins is built
-
Running experiments, testing ideas and building working demos as the product evolves
-
Improving and optimising data processes, tooling and cloud‑based architectures
-
Creating monitoring and visualisations to track system health, performance and progress

-
Strong problem‑solving skills with a good understanding of business needs
-
Experience building and maintaining data pipelines and data‑driven applications
-
Confidence working with Python, SQL and modern data engineering tools
-
A solid understanding of databases, ETL processes and data architectures
-
Experience working with cloud platforms (Azure preferred; AWS or GCP also welcome)
-
Enjoyment of working in small, fast‑moving teams with a high level of ownership
-
Clear communication skills and a desire to keep learning and growing
