Directing the work: Scope and shape work for the contributors on your team, set the pace, and keep things moving

Stakeholder relationships: Build genuine, trusted relationships with people across the business, both technical and non-technical

Data science SME: Act as the data science point of reference for the wider Customer iQ team, and support the model build team when needed

A track record of turning analytical outputs into data products or use cases that make a real difference

The ability to explain technical concepts clearly to non-technical people

Experience delivering data science work end-to-end

Experience shaping work for others and helping less experienced people grow
