Job description

Our Assistant Methodologists help shape the quality, reliability and impact of statistics across government. They carry out research and analysis, develop and improve statistical methods, and provide advice and guidance to colleagues, policymakers and partners.

You’ll work alongside specialists across ONS, academia, other government departments and international statistical organisations to solve analytical challenges and improve the way statistics are produced and used.

Where could you be based?

We are recruiting across three divisions within the Methodology and Quality Directorate:

Quality and Improvement Division Improves the quality of statistics and data across government by developing guidance, supporting quality reviews, providing advice and consultancy, delivering training, and building capability through cross-government collaboration.

Methods and Statistical Design Division Helps ensure ONS statistics are underpinned by robust methodology and high- quality statistical design. The division develops and improves methods, explores innovative solutions, and supports the delivery of trusted, efficient statistics.

Methods and Analysis Capability Division Supports analytical capability across government by developing technical training, driving continuous improvement and innovation in analytical methods, and working across the Analysis Function and Government Statistical Service (GSS) to improve statistical standards and collaboration. In addition, the division also supports social statistics projects with cross-cutting methodological qualitative and quantitative research.

  • Help develop, test and improve statistical methodologies
  • Communicate findings through reports, presentations and stakeholder discussions
  • Work collaboratively with customers, colleagues and multidisciplinary teams
  • Contribute to specialist methodology teams and wider project groups
  • Share your knowledge and support others as your experience develops
  • Manage your own work with support, guidance and training from experienced colleagues

What we’re looking for

We’re interested in candidates with strong quantitative and/or qualitative research skills who enjoy solving problems, working with data and improving the way evidence is produced and used.

Whether your background is in statistics, social research, data science, economics, behavioural science or another analytical discipline, you’ll have the opportunity to develop your expertise while working on projects that support decisions across government.
