Lead end-to-end data and reporting projects, from requirements gathering through to delivery.
Collaborate closely with cross-functional teams to deliver consistent, accurate, and accessible data.
Uphold data quality, governance, and security best practices.
Provide technical guidance and mentorship to junior data professionals.

You will have the following qualifications & experience:
Proven experience developing and deploying solutions using Power BI.
Strong proficiency in Python, particularly for data processing and automation.
Deep working knowledge of SQL and Oracle databases.
Hands-on experience with Airflow for workflow orchestration.
Understanding of ETL/ELT processes and data architecture principles.
Strong project management and communication skills.
Fluent in English.
Must hold a valid British passport (due to project security requirements).
