  This is a hybrid working role; therefore, your time will primarily be split between working from home (in the UK) and our London Office. However, there will also be an expectation to visit other locations as the need arises.
• Our Engineers currently work from the office roughly twice a week to connect and, on a more ad-hoc basis, to attend key meetings, but again the frequency is dependent on the business needs. Our offices are open five days a week for those who prefer to work from the office more regularly.
