Please read first: this role is fully remote from anywhere in Europe. We list it as Madrid/hybrid only because openly remote postings get flooded with fake applications. If you are based in Europe, you are in scope.

Our client is a product-led tech company where data is the product itself. They are looking for a Senior Data Engineer to take real ownership of their core data platform.

The team is small and senior by design. You won't be handed tickets: you will own projects end to end, from shaping the problem with product and leadership to running the solution in production and keeping it healthy. You will also have a direct say in how the platform's architecture evolves.

What you'll do

- Build and tune the analytical layers that power the product and its APIs
- Take full responsibility for ingestion pipelines across a wide range of sources
- Raise the bar on data quality, reliability and observability




- Partner with backend and product engineers to ship data-driven features

What you bring

- Experience in product-based companies, ideally ones where analytics or data is the core offering
- Strong ownership: a track record of taking pipelines from ingestion through to analytics and being accountable for the outcome
- Advanced SQL, ideally on Postgres
- Hands-on experience with OLAP and analytical databases such as ClickHouse or DuckDB
- Strong Python, with Polars and/or pandas
- Experience with an orchestration tool such as Airflow or Prefect
- Fluent English , written and spoken
- Large-scale ingestion or web data and scraping experience

Package

Up to €135,000 per year, depending on experience.

One more time: this is a remote position open to candidates across Europe, not a hybrid role in Madrid.
