THE ROLE:

You'll own client analysis from scope to delivery, working both independently and as part of a wider client team to turn customer data into action.

You'll bring those insights to life for the client, presenting your work with confidence and authenticity. You will need to explain it in a way that suits each audience and build relationships where clients trust your judgement as much as your numbers.
