Success in this role means pipelines and analytical workflows are reliable, maintainable, and trusted metrics are clearly defined, methodologically sound, and consistently applied and analytical outputs are accurate and resilient enough for repeated commercial use. Data dependencies, assumptions, and limitations should be documented and understood, while manual analytical work should decrease over time as scalable solutions are introduced.

• Structured and practical: you can move from ambiguous business questions to executable analytical solutions
• Comfortable collaborating with client-facing and non-technical stakeholders, even if this is not the center of gravity of the role
• Strategic enough to improve the system, not just execute within it
• Significant experience in data science, analytics engineering, analytical product work, or a similar role in a data-rich environment
