We are looking for someone who can start in February/March 2026 for six months.

All the responsibilities we'll trust you with:

OPERATIONAL DATA QUALITY SUPPORT

You’ll carry out predefined, recurring data quality checks (e.g., completeness, consistency, plausibility) based on existing guidelines and standards. You’ll support the identification, documentation, and follow-up of data quality issues and contribute to basic data cleansing and harmonization before checks are performed. You’ll also help keep operational data quality reports and simple monitoring views up to date.

TICKET HANDLING & BUSINESS SUPPORT

In this internship, you’ll support the processing of tickets from business partners related to data quality or data-related questions.

You’ll use Excel and basic SQL to extract, validate, and prepare data for further use. You’ll perform simple analyses that help with prevention measures and day-to-day operational decisions. You’ll prepare structured summaries, basic reports, and simple visualizations to communicate findings and support the documentation of data sources, applied checks, and analysis steps.

COLLABORATION & LEARNING

Additionally, you’ll work closely with the Media Data Governance and Enablement Team to learn and apply established processes, methods, and standards. You’ll support alignment with business partners on data definitions and recurring data questions and contribute to continuously improving documentation and operational workflows over time.
