• Work with large-scale datasets in Apache Spark and distributed computing environments, ensuring efficient data processing.
• Support testing, validation, and implementation of new or enhanced data solutions.
• Use GitHub for version control, code collaboration, and change management.
• Document data mappings, transformation rules, analytical findings, and data lineage.
• Communicate findings, risks, and recommendations clearly to both technical and non-technical stakeholders.

• Strong practical experience with Python, particularly:
• Pandas for data manipulation, cleaning, aggregation, and analysis.
• PySpark for large-scale data processing and transformation.
• Working with structured datasets and implementing data validation logic.
• Hands-on experience with Jupyter Notebook for Python/PySpark development, exploratory data analysis, prototyping, and data validation.
• Good understanding of Apache Spark and distributed computing concepts, including DataFrame operations, partitioning, and performance optimisation.
• Solid understanding of data wrangling, ETL processes, data transformations, and data quality controls.
• Experience analysing large datasets and investigating data discrepancies across multiple sources.
• Familiarity with Git/GitHub, including branching, pull requests, and collaborative development workflows.
