A note on how we run interviews

We use AI only to transcribe our interviews so we can focus fully on you instead of scribbling notes. The AI does not take part in any decision making at any stage. All hiring decisions are made by real humans based on the conversation we have with you. If you require adjustments to take part in the recruitment process, please let us know, we’ll do our best to support you.

Location and work pattern

All of our new UK team members are asked to work on site here at Abingdon during their first three months with us. We offer flexible, hybrid working where possible upon completion of probation. We welcome applicants from all backgrounds and aim to create a fair, supportive recruitment process. To keep things clear, this role needs someone who already has the permanent right to work in the UK. If a role calls for unique expertise that’s hard to find locally, we may explore sponsorship options — though this is uncommon.
