• This role will enable you to further build your knowledge and experience in exploratory data analysis, inferential statistics, and machine learning, including: 
  
• Clustering techniques (e.g., k-medoids, hierarchical clustering)  
  
• Predictive modelling (e.g. Classification and Regression Trees (CART), Linear Regression, Random Forest, Gradient Boosted Models) 
  
• Natural Language Processing (NLP) with a focus on social listening and topic modelling 
  
• Integration of generative AI and LLMs in qualitative and survey research processes 
  
• Inferences about subpopulations (Small Area Estimation (SAE), Multilevel Regression and Poststratification (MRP)
  
• You will produce technical reports and sections of high-profile policy reports to be published by NatCen, government departments and agencies, and other clients and partners.  
  
• You will primarily work with survey data with complex survey weights and administrative data, with the opportunity to also work with social data and GIS data.  
  
• You will work closely with subject matter experts on policy but will be expected to quickly gain a basic understanding of new policy issues. 
  
• You will combine advanced data science techniques (machine learning, NLP, data engineering) with robust quantitative research methods (survey analysis, causal inference, MRP) to produce insights that directly inform social policy.
  

• 
  
• You will be joining Britain’s largest independent social research organisation, championing the use of data science to generate insights that help make life better. 
  
• You will join a growing team, where you will share research approaches, fostering a collaborative and innovative work environment. 
  
• You will have opportunities to feed into the future direction of data science and analysis at NatCen 
  

• 
  
• The role will involve direct contact with clients and collaborators, where you will be advising on analytical methods.  
  
• You will collaborate with colleagues across specialisms to design research proposals for clients. There is some scope to also pursue and deliver work supported by academic funding.

• 
  
• Master's in a relevant field (Data Science, Computer Science, Statistics, etc.) or demonstrated experience through professional development, other learning, or Bachelor’s degree with additional equivalent experience.
  
• Experience with practical application of clustering, predictive modelling, and NLP techniques, with familiarity with at least one major machine learning library (eg. Scikit-learn, statsmodels, spaCy, mlr).  
  
• Proficiency in Python; knowledge of R or SQL is a plus. 
  
• Familiarity with coding best practices, such as version control, functional code, and documentation 
  
• Excellent communication, presentation, and report-writing skills. 
  
• Ability to work collaboratively in a multidisciplinary team.
