Flexible Working
We understand that life isn’t one-size-fits-all, and we’re committed to helping you balance your personal and professional commitments. That’s why we embrace flexible working. Many of our team members work in different ways, including part-time arrangements—so if flexibility matters to you, let’s talk about it at interview.
We also offer a hybrid working model, giving you the best of both worlds: three days a week in the office and two days working from home. Plus, to make your commute easier, we provide free shuttle buses from Horsham Station straight to our campus.
