• Investigate data discrepancies, identify root causes, and provide actionable insights to business and technical stakeholders.

• Perform data quality checks, reconciliations, and consistency assessments to ensure accurate and reliable reporting outputs.

• Collaborate with data engineers to define, implement, and optimise data transformations and ETL workflows.

• Gather, analyse, and translate business and regulatory reporting requirements into technical specifications and data transformation logic.

• Assess the impact of changing reporting requirements on existing datasets, data pipelines, and deliverables.

• 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.

Skills & Experience

• 4-5+ years of experience in Data Analysis, preferably within banking, financial services, or regulatory reporting environments.

• Strong proficiency in SQL, including complex joins, CTEs, aggregations, window functions, and data reconciliation.

• 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.

• Ability to translate business requirements into technical data specifications and work effectively with data engineering teams.

• Strong analytical thinking, problem-solving skills, and attention to detail.

• Experience collaborating with business stakeholders, data engineers, and cross-functional teams.

• Excellent communication skills, with the ability to explain complex data issues clearly.

• Fluent English, both written and spoken.
