ABOUT THE ROLE
We are searching for a talented and technically exceptional individual to join our OpenDoor team as a Data Scientist, dedicated to the delivery of Prime Video's expanded geo holdout programme across Europe. This is a full-time permanent position based in London. The role reports into the EU Measurement Lead. This is a rare opportunity to own the technical backbone of one of the most analytically rigorous media measurement programmes in market - designing and operating the infrastructure that enables up to 55 geo holdout experiments across seven European markets, including the UK, Germany, France, Spain, Italy, and optional extension into Poland and Turkey.

- Construct and maintain the NUTS3-to-platform geo lookup table, mapping regional boundary data from ONS and Eurostat sources to platform-specific geo targeting formats across Meta, DV360, X, Sprinklr, and all other in-scope media platforms.
- Build and operate the weekly campaign-to-experiment calendar matching script, ensuring geo exclusions are flagged, applied, and verified ahead of each experiment activation.
- Develop and maintain API scripting and bulk upload templates to apply and verify geo exclusions directly within each platform's native geo-targeting capabilities.
- Produce and validate weekly verification reporting at NUTS3 and postcode level, delivered to key Prime Video stakeholders every Friday, clearly documenting impression leakage rates against the programme's defined accuracy thresholds.
- Own human oversight of the agentic QA solution - reviewing automated flags for impression leakage, exclusion drift, and reporting anomalies.
