Additional details

A full UK driving licence is essential, due to regular travel between Defence sites, many of which are remote and not easily accessible via public transport.

There will be a requirement to attend other Defence sites in the UK (or potentially occasional overseas visits) during this role. There may also be a requirement for travel to meetings or to attend training courses at other locations. This job role is not suitable for hybrid working.

If not already held, the successful candidate will be required to attain DV clearance.

Please note this position is open to sole UK Nationals only.

As the post holder will have access to very sensitive information, there are limitations on travelling to a small number of countries and we will undertake additional security checks as part of the recruitment process.

Further details will be provided at the conditional offer stage.
