## Description

As a Junior Data & AI Engineer (m/f/x) at Travelcircus, you will build AI agents and automations that take over repetitive work across the company, from first prototype to production. You will also keep our data foundation running: maintaining and extending our ETL pipelines in Airflow, improving our data warehouse, supporting our web tracking setup, and building Metabase dashboards that give stakeholders timely and accurate insights. You'll work closely with the DevOps team on deployment and infrastructure, and support our monthly financial reporting. This full-time position is based in our vibrant office in Berlin.

Things you will work on

 * Build AI agents and automations: Identify repetitive processes across the company, then design, build and deploy LLM-powered agents and workflows (e.g. Claude API, tool use / MCP) that take them over, from prototype to production.
 * Own our data pipelines: Maintain and extend Airflow DAGs and the Dockerized Python services behind them, deployed via GitLab CI/CD.
 * Maintain and improve our DWH: Work across Trino, MariaDB, BigQuery and MongoDB, covering data modelling, performance and data quality.
 * Enable the business with data: Build and maintain Metabase dashboards and reports for marketing, sales and leadership.
 * Own marketing analytics: Maintain and analyze Web (GA4), A/B testing and attribution data
 * Support financial reporting: Prepare monthly financial reporting together with finance, and help automate it over time.
