Senior Data Engineer

Senior Data Engineer 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 Bonus points An infrastructure mindset: deployment, scaling, monitoring, performance 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.
