Your mission Build and run the pipelines that carry a tender from the source portal to the customer's screen: ingestion, merge, enrichment, delivery. You own concrete pieces of the data pipeline end to end — not tickets handed to you, but the sources, jobs and tables behind them. What you'll actually do Own scrapers and ingestion for a set of national portals across Spain and Italy, where reading the source in its original language is part of the job.

Write and maintain orchestrator flows: retries, backfills, alerting, and a clear answer to "Did today's run actually land?" Work on merge, dedup and reconciliation — the same tender arrives three times, in three shapes, and only one version can reach the customer.

Ship AI enrichment steps: batch LLM extraction of requirements, embeddings, OCR on attachments.

Write SQL that survives production: query plans, indexes, JSONB, partitioning, CONCURRENTLY migrations. Guard data quality with tests and checks that fail loudly before a customer finds the gap.

Idóneo profile Real SQL: you can read an EXPLAIN and say why the plan is bad, not just that it is slow. Python you'd put in production: typed, tested, and readable six months later. Pipelines you've actually operated:



with an orchestrator (Prefect, Airflow, Dagster, ArgoWorkflows) and the 3 a.m. failures that come with them.

Builder by default: you see a manual process and your first instinct is to automate it.

Comfortable with messy sources: broken HTML, inconsistent XML, PDFs that were scans of scans.

Experience ~2–4 years building data pipelines in production. ~ Hands-on with PostgreSQL beyond writing queries — you've had to make one fast. ~ Exposure to LLM-based extraction is welcome; curiosity about it is mandatory. What you won't find here No micromanagement: we trust you to own your part of the stack. No "standard" 9-to-5 mentality: we care about outcomes and we are looking for people who are willing to go the extra mile.

No "we've always done it this way" excuses: we're here to disrupt, not to follow old patterns.

Our Tech Stack Data & Infra: Python, PostgreSQL, Prefect, K3s/ArgoCD, AWS AI: batch LLM extraction, embeddings, OCR Compensation RAL €40,000 – €60,000 + equity, depending on seniority and profile.
