About the RoleWe're looking for a Data Engineer with an interest in geospatial data to take ownership of one of the most critical foundations of our product: the address database.This is not a typical data pipeline role. You'll work on building and maintaining a highly accurate, unified address system that powers data linking, search, and product quality across the platform. In Belgium, this is particularly complex due to fragmented government data sources, historical changes, and inconsistent formats—making this a genuinely challenging and high-impact problem space.If address resolution fails, everything built on top of it suffers. That's why this role sits at the core of our data platform.What You'll DoOwn and evolve the address database, the backbone of our data platformIngest, clean, and unify multiple external data sources into a consistent formatBuild and improve pipelines for address matching, linking, and enrichmentHandle complex geospatial challenges such as historical address changes, merging municipalities, and inconsistent formatsEnsure high data quality and accuracy across all downstream use casesCollaborate with product teams (e.G. agent tools, listings, search) to enable reliable data usageContribute to broader data engineering initiatives within the Core Data teamWhy This Role MattersDirect impact on product quality across the entire platformWork on one of the most complex and complete address datasets in BelgiumSolve real-world geospatial problems (not just theoretical GIS work)High ownership and autonomy within a small, experienced teamOpportunity to shape how foundational data is built and used across multiple productsWhat We're Looking ForMust-haveStrong background in Data EngineeringExperience designing and maintaining data pipelines (ingestion, transformation, validation)Solid SQL skills and experience working with large datasetsStrong problem-solving mindset and ability to reason through complex data challengesAbility to work independently and take ownership of a critical domainNice-to-haveExperience with geospatial data (GIS) or strong interest in learningExperience with AWS-based data infrastructureExperience with Elasticsearch / OpenSearchFamiliarity with PHP (or willingness to learn)Exposure to multi-source data integration or messy/fragmented datasetsKnowledge of Belgian geography/data sources (a plus, not required)Team & EnvironmentYou'll join the Core Data team (6 engineers/scientists) within a wider engineering org of~60. This team acts as the foundation for multiple product teams, meaning your workwill be widely used across the business.The team is collaborative, pragmatic, and focused on solving real data problems ratherthan over-engineering solutions.Hiring ProcessRecruiter screeningTechnical assessment (Python/AWS-based or equivalent)Technical discussion (problem-solving & system design)Final interview with hiring managerAdditional NotesThis is a new role created to unlock broader data engineering capacityYou won't be starting from scratch—there's strong existing infrastructure to build onWe're open on background: strong Data Engineers with an interest in geo arepreferred over pure GIS specialistsLocationBelgium (Brussels or Ghent preferred)Hybrid: ~2 days/week in office
