Senior Data Engineer
GRESB · Amsterdam
What you will do
GRESB is an industry-led organisation on a mission to provide the financial industry with standardised, validated sustainability data on real assets. Investors and managers rely on that data to allocate capital, and we are investing in how we deliver it so it is easier to access, trust, and act on, in both human and automated workflows.
In practice that means building a governed, scalable data model that can support our assessments as they grow and evolve, and making our data easier to work with for the teams and systems that use it.
This only works if the data underneath is trustworthy and well defined, for the people using it and for the systems and AI reading it. We are hiring a Senior Data Engineer to build that foundation.
What you will do
You would join our data team, working closely with the Product team. The work is split between keeping the annual benchmark running and building the data foundations for what comes next, so you would touch both legacy and greenfield.
- Build and maintain the data pipelines and services that support our yearly evolving standards and methodology, and re-architect or retire those that no longer keep up.
- Shape the data models and schemas beneath our products, and the serving layers that expose them to reporting and analytics.
- Own data quality and reliability through validation, automated testing and production monitoring, to ensure issues are caught as early as possible, never first by the people consuming the data.
- Make our data discoverable and documented, including definitions, lineage and pipeline logic, so the teams and systems that consume it can self-serve.
- Guide architecture decisions in the areas you own: frame the options and the trade-offs, and bring them to a decision the team commits to. Help raise engineering standards through design and code review.
Our stack: Python (pandas, polars and fastapi), Parquet on S3 with Athena, Postgres, kubernetes, Terraform, ArgoCD and GitHub Actions. Around it sit a Rails portal, Java application services, and LLM validation on Bedrock.
