• Curiosity about real client problems, willingness to ask questions and ability to explain your thinking in clear written and spoken English.
• A relevant degree or equivalent practical experience in a quantitative or social science field.
• Useful additional experience
• Exposure to public policy, government, research or evaluation.
• Hands-on exploration of large language models, including checking responses against source material, experience with AI agents is welcome but not required.
• Experience with Git, cloud services, data visualisation, collaborative projects or presenting technical work to a nontechnical audience.

What you can expect

You will learn from colleagues with a range of technical and subject expertise while contributing to complex, varied projects. We will support your career development through ongoing training, feedback and opportunities to deepen both your data science and consulting skills.
