Design and implement data quality checks so that issues are caught early and automatically
Handle data cleaning, missing values, and inconsistencies so downstream users can rely on the data
Perform statistical analysis to identify anomalies, trends, and irregularities, and share clear reports with the team
Maintain and manage databases, including backups, storage, and overall data health
Develop a deep understanding of the datasets we use and serve as the go-to person for data-related questions
Coordinate with internal teams and external providers to resolve data issues
What We're Looking For:
Strong programming skills in Python
Good understanding of SQL and working with databases
