We are supporting a public sector client in hiring a Data Analyst to join a multidisciplinary data team working on a complex, multi-source data platform. This is a hands-on analytical and coding role focused on profiling and assessing data ingested from multiple source systems, identifying where platform functionality does not fully cover or accurately process incoming data, and producing clear, evidence-based findings that directly inform engineering decisions.
The source data is accepted as provided and cannot be modified. The successful candidate will develop a deep understanding of that data, its structure, patterns and edge cases, and work closely with data engineers to prioritise and address coverage gaps and processing issues. A core part of this role involves writing Python code to automate analytical tasks, generate and manipulate YAML configuration files and support broader data engineering workflows.
This role suits an experienced Senior or Mid-Level Data Analyst with at least 5 years of experience, strong hands-on coding ability across Python and SQL, and a sharp, methodical analytical mindset comfortable working at pace in an Agile, multidisciplinary environment.

- Identify and document gaps where platform functionality does not fully cover, correctly interpret or accurately process the data being received
- Investigate discrepancies between expected and actual data processing outcomes, clearly articulating where platform logic falls short
- Produce clear, evidence-based findings that enable data engineers to prioritise and address coverage gaps and processing issues
- Write Python scripts to automate data analysis tasks, generate YAML configuration files and support repeatable, config-driven workflows
- Develop and maintain SQL queries for exploratory analysis, data profiling and validation of processing outputs
- Define and document data coverage rules, assessment criteria and known platform limitations in collaboration with technical and business teams
- Contribute to documentation of data definitions, data lineage and known processing constraints across the platform
- Participate in Agile delivery ceremonies and contribute to continuous improvement of team practices
Essential Skills
- Strong Python proficiency with the ability to write clean, maintainable scripts for automation, data analysis and YAML file generation and parsing
- Strong SQL skills including complex queries, joins, aggregations, window functions and performance optimisation
- Solid understanding of YAML structure and experience working with YAML-based configuration files using Python libraries
- Understanding of medallion architecture, Azure Data Lake Storage and Databricks, with a focus on Parquet files and Delta tables
- Experience working with Azure cloud services including Azure Synapse Analytics
- Demonstrated experience in data profiling across large, complex or multi-source datasets, identifying patterns, anomalies and edge cases
- Ability to interpret and work with data schemas and data dictionaries
- Strong analytical mindset with exceptional attention to detail and a methodical approach to problem-solving
- Confident communicator able to present technical findings clearly to non-technical stakeholders
