ABOUT THE OPPORTUNITY 

We are looking for a Data Engineer to join our ONE Data team, working with a team of data scientists, analysts, researchers and data visualization experts. In this role, you will help design, build, and improve the data infrastructure supporting our data and analysis tools and platforms.

ONE Data is building a shared, open infrastructure for the development sector. It aims to let analysts, researchers, journalists and policymakers answer questions about development, health, and climate finance in minutes, not days or months.

As a Data Engineer you will be working on our core infrastructure layer: modular, open-source pipelines, tools, and a knowledge graph which stitch together development financing and policy data. Your job will be to take raw, (potentially) messy, fragmented data and information, transforming it into clean, trusted, analysis-ready knowledge and data that fuels everything we build.

IN THIS ROLE, YOU WILL:

• Design and develop data pipelines, including ETL workflows and tools which ingest heterogeneous sources (APIs, CSV, XML, PDFs, web-scraped HTML) at scale.
• Model the ONE Data Knowledge Graph, crafting schemas and enrichment logic/tools which connect finance flows, programmes, geographies, and outcomes.
• Productionise AI/ML, collaborating with the data-science/product team to deploy AI classification, search, exploration, and analysis tools.
• Embed data quality and governance, owning tests, lineage, observability and documentation for all data compiled/modelled by ONE Data.
• Partner across disciplines, translating policy questions into data features, pairing with researchers and advocates on ad-hoc analyses, supporting other data teammates in modern engineering practises.
• Contribute to open-source tools: all our work is open source by default, and we design and develop aiming to create building blocks that the sector can reuse, repurpose, and build upon

• Familiarity with Data Commons or working with public data.
