Data & Insights Engineer, Customer Solutions

About Daltix

Daltix helps leading FMCG and retail companies make better decisions using reliable, accessible and carefully curated product data.

Every day, we collect, standardize and deliver large-scale data on prices, promotions, products and assortments. Our customers—including companies such as Colruyt Group, YouGov and Danone—use this information to understand their markets, monitor competitors and identify commercial opportunities.

Data quality is central to what we do. We remove the complexity of collecting and preparing retail data so our customers can focus on using it.

About the role

We are hiring a Data & Insights Engineer – Customer Solutions for a hands-on, customer-facing role bridging data engineering and analytics. You will build data pipelines and models, analyze large-scale retail datasets, and work directly with customers to turn business needs into practical technical solutions.
