Your mission Build and run the pipelines that carry a tender from the source portal to the customers 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 youll 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 todays 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. Adecuado profile * Real SQL:



you can read an EXPLAIN and say why the plan is bad, not just that it is slow. * Python youd put in production: typed, tested, and readable six months later. * Pipelines youve 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 — youve had to make one fast. * Exposure to LLM-based extraction is welcome; curiosity about it is mandatory. What you wont 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 "weve always done it
