Senior Data Engineer, Marketing Effectiveness

About MarketOne

MarketOne International is a global provider of B2B marketing services, helping enterprise companies identify new prospects, develop demand generation programmes, and convert pipeline to revenue. With delivery capability across EMEA, Asia Pacific, and the Americas, MarketOne serves many of the world’s largest companies.

Our Data Services practice sits at the centre of everything we deliver. We are expanding that practice to support a growing portfolio of enterprise engagements, with a flagship new programme at the forefront — a modern, cloud-native data platform built on Databricks that will define how we deliver unified marketing data and attribution at scale.

About the Role

This role is primarily a Databricks build. You will take ownership of a greenfield platform on Databricks and Delta Lake, responsible for ingesting signals from marketing platforms, and transforming them into a unified account journey view that drives attribution and media optimisation across a major enterprise engagement.

Beyond that core programme, you will also contribute to existing client work on our Microsoft and Azure data stack — SQL Server, SSIS, and Azure Data Factory — where your broader data engineering experience will add immediate value. What You Bring
