A fantastic opportunity for a Data Scientist looking for the opportunity to work on genuinely interesting problems, apply rigorous statistical thinking to large-scale behavioural data and have a real impact. This is a chance to join a small, high-performing Data Science team where you'll have significant exposure to interesting projects, experienced colleagues and real client challenges.
Working for one of the world's largest consumer behavioural data companies, providing deterministic behavioural data to many of the world's leading brands and platforms, including Google, Meta, Netflix and the BBC.
The Data Science team works with billions of consented consumer events across search, browsing, AI, social, retail, web, app and purchase activity, turning complex data into findings that clients can act on.
The Role:
- Work with large-scale behavioural datasets covering consumer activity across multiple platforms
- Define cohorts and datasets using SQL, including complex aggregations, CTEs and window functions
- Apply statistical methods including hypothesis testing, confidence intervals and experimental analysis
- Work with causal inference techniques such as A/B testing, difference-in-differences and matching
- Investigate selection bias, confounding and other factors that could affect the validity of results
- Develop and maintain data aggregation pipelines and datasets used across the business
- Contribute to PII detection and client reporting processes
- Validate analytical results against source data and investigate unexpected findings
- Write clear, maintainable Python code that can be understood and reused by others
- Work collaboratively through GitHub, pull requests and code reviews
- Present findings, methodologies and caveats clearly to clients and internal stakeholders
- Use AI and coding assistants effectively while taking full responsibility for reviewing and validating their output
- Contribute to the development of analytical and data products as the team evolves
