Partner with analysts, business stakeholders, and engineering teams to translate business requirements into scalable data solutions.
Enable self-service analytics capabilities through well-structured semantic layers and governed datasets.
Support and optimise BI and reporting platforms such as Looker, Power BI, or equivalent tools.
Ensure data structures and models support both operational reporting and strategic analytics requirements.

Data Quality, Governance & Reliability

Implement data quality controls, validation frameworks, reconciliation processes, and monitoring capabilities.
Proactively identify and resolve data integrity, consistency, and performance issues.
Establish observability and operational monitoring for data pipelines and platform reliability.
Contribute to data governance, lineage, cataloguing, and metadata management practices.
Ensure data platforms and engineering processes comply with security, privacy, and regulatory requirements.

Collaboration & Leadership

Collaborate closely with Product, Engineering, Operations, Finance, and Business stakeholders to deliver impactful data solutions.
Mentor and support junior engineers and analysts within the broader data function.
Contribute to data engineering standards, best practices, and platform strategy.
