• Expanding the use of AI, synthetic data and machine learning
• Collaborating with marketing to shape new, data-led propositions
• Upskilling team members in data science and statistical thinking
• Representing the agency externally in thought-leadership or event settings (optional)

• Strong command of quantitative analysis methods, including regression, segmentation and more advanced statistical techniques
• Proficiency in tools like Python, SQL, SPSS, Q or R
• Confidence working with and integrating non-survey data sources such as 1st-party or behavioural data
• Ability to explain technical findings clearly to non-technical audiences
• An innovative and proactive mindset with a love of new ideas, tools, and learning

Nice to Have

• Experience establishing data science workflows in a commercial setting
• A track record of upskilling or training others in data/statistics
• A desire to contribute to external thought leadership (e.g. presenting at events)
