If required, you must also be able to

• Be “on-call” throughout the day and night for 1 week out of every 4
• Work a specified number of additional hours

The nature of the attendance requirements and duties of this role mean it isn’t suitable for HMRC’s hybrid working arrangement. FIS will support colleagues receiving the Flexibility Payment to work from home for some of the time, but this won’t be fixed to a number of days per week or month, or to specific days of the week. The role’s attendance requirements also mean some Flexible Working arrangements may not be available – please discuss your situation with us before accepting this role.

Candidates are asked to provide 1 location preference only. Please ensure that you only apply for a location that you are willing and able to work from, as we will only make one offer of employment. Any additional notes included in a ‘Further Location Preferences (optional)’ field within the application form, will not be considered.
