Full-time, 37.5 hours a week, Monday to Friday. Work primarily from our London HQ during UK business hours. Discuss any flexibility you need at the first conversation.

Where you sit in the range reflects the scope you can own and the relevant skills you bring. We discuss this early, using the published band rather than your previous salary.
