• Making day-to-day technical decisions on feature engineering, model selection, analytical techniques and data requirements within agreed team standards.
• Resolving technical challenges during model development and deployment, seeking guidance from the Senior Data Scientist on complex or high-impact decisions.
• Delivering high-quality, reliable outputs that directly influence project success and provide clear, actionable value to stakeholders.

What we’d like you to bring:

• A strong foundation in data science, including machine learning techniques, statistical analysis, feature engineering and model evaluation, with hands-on experience building and deploying models.
• Proficiency in Python, SQL and data manipulation, alongside a solid understanding of data quality, governance and ethical considerations in analytics.
• Experience translating business problems into analytical solutions, with circa two years in data science, machine learning or a related analytical role.
• The ability to work collaboratively in cross-functional teams, exercising ownership and independent judgement on day-to-day modelling while working under the technical guidance of a Senior Data Scientist.
