Key tasks include:

• Lead on data extraction, transformation, and quality assurance processes using SQL and other analytical coding techniques.
• Work proactively with the Welsh Government, Medr and other data suppliers and users to identify and access relevant datasets, ensuring ethical use and compliance with governance standards.
• Collaborate with the Senior Research Officer to ensure statistical evidence complements qualitative findings and supports mixed-methods studies.
• Promote and embed robust data management practices across the team.
• Lead complex statistical analysis to meet stakeholder needs, applying appropriate methods and coding practices in SQL where necessary.
• Develop reproducible and transparent analytical processes with strong quality assurance and version control.
• Evaluate opportunities to use AI and machine learning techniques to improve efficiency and insight within statistical production.
• Design and deliver interactive dashboards and data visualisations using Power BI, and other tools where appropriate, to communicate insights effectively.
• Present analysis in clear and engaging ways, tailoring outputs to diverse audiences and maximising impact.
• Provide expert advice on statistical interpretation to stakeholders, ensuring outputs inform decision-making.
• Build and maintain strong relationships with internal and external stakeholders, including Welsh Government, inspection staff, and other partners, ensuring analytical work is user-driven and aligned to policy priorities.
• Translate complex analytical requirements into tangible projects that meet stakeholder needs in a timely manner.
• Proactively seek feedback to ensure outputs remain relevant and accessible.
• Line manage and mentor junior statisticians, fostering a culture of professional development and high analytical standards.
• Champion innovation in statistical methods, visualisation, and dissemination, including exploring the role of AI in supporting Estyn’s work.
• Contribute to the wider Government Statistical Service (GSS) and Analysis Function community, sharing best practice and learning.
• Manage and monitor allocated budgets, ensuring effective financial control, transparency, and value for money in the use of public funds. Contribute to financial planning and provide assurance that resources are deployed efficiently to achieve organisational priorities.
