About the role

This role will employ a wide variety of data science skills to create a fantastic consumer and partner experience.

• Experimentation: can we standardize how we run A/B tests and automate all our test analyses? How can we run 10x more experiments in 1-2 years?
• Reporting and storytelling: how can we succinctly summarize how our business is performing? What metrics should we track, how should we define them, and why?
• Data modelling and data architecture: how do we structure our data so that it can quickly answer most questions? How do we expose the data to other teams?

• Share customer insights, develop metrics, and explain testing results to technical and non-technical team members.
• Identify complex issues within your area, simplify them, and work with other teams to create solutions for broader company challenges.
