* Data-driven, with the ability to turn insights into action
* Confident partnering cross-functionally with Product, Engineering and Sales
* Technically confident and quick to pick up new platforms
* An excellent communicator: clear, calm, credible and trusted
* Highly organised and able to juggle multiple priorities
