You’re happy to roll up your sleeves when something needs doing, and you can adapt to very different personalities across a small team. Different backgrounds and ways of thinking are actively welcomed. Flexibility The role is the equivalent of two days a week, and how you make that up is flexible. Three shorter days within school hours works just as well as two full days. For the first couple of months they’d like you in the office regularly to learn how everything works, and after that it’s hybrid and largely your call. The founders built this business while raising young children, so they understand what flexibility really means. There’s scope for the role to grow in hours and seniority over time if you want it to.
