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.
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.
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
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 foundation end-to-end
4+ years total, 3+ shipping production data infrastructure (pipelines, warehouses, observability)
Strong Python and SQL. Reads code to understand data, doesn't just trust schemas
Has worked with LLM outputs in production. Has built or seriously used an eval framework
Comfortable with cloud data warehouses (BigQuery preferred, Snowflake/Redshift fine), distributed processing, batch and streaming
Cares about outcomes over process, clarity over frameworks
Comfortable with startup environment high autonomy, high ambiguity, high speed
Bonus
Built or seriously contributed to retrieval/RAG, document extraction, or OCR systems
GCP / BigQuery / Temporal experience
Background in audit, compliance, legal, or another document-heavy professional services domain
Speaks German
No one checks every box. If you’ve shipped retrieval systems and like owning evaluations and pipelines, let’s talk.
