ABOUT US We’re Cortea, a Berlin startup transforming audits with AI. Manual, document-heavy audits waste expert time while demand keeps rising. Our AI-powered software and specialized AI agents remove the repetitive work so auditors can focus on judgment. Backed by top-tier VCs with >10m funding, with a working product and paying customers, we’re rapidly scaling. We value first-principles thinking, speed, trust, and kindness. We build side by side in our Berlin office. YOUR ROLE You'll own the data and quality infrastructure that makes Cortea's AI pipeline trustworthy and continuously improving. Pipeline data, evals, observability, ground truth, retrieval quality. You're a builder. You write production Python. You think in pipelines and feedback loops, not notebooks. You've worked with LLM outputs in production and have strong opinions about how to make probabilistic systems measurable. WHAT YOU’LL DO - Build and operate the data pipelines behind Cortea's AI. Every model call, every pipeline state, every customer document, captured, queryable, observable - Create the foundation for evaluating agent performance and quality. Make probabilistic quality measurable, regression-detectable, and reproducible across model versions - Maintain observability of agent cost and optimizations - Improve document extraction and retrieval quality on the documents that matter most (financial statements, audit reports, complex tables) - Maintain the Data FBigQuery foundation engineers, PMs, and founders use to make decisions - Partner with engineering and product to turn customer feedback into measurable, shipped improvements SUCCESS AT 6 MONTHS - Eval framework live across our core pipelines — every ship is measured before it goes out - Cost and quality observability on every pipeline run, alerting that catches regressions early - Document extraction and retrieval quality measurably better on the documents customers care about most - Trusted by engineers and founders to own the data f
