Office attendance
The Department operates a discretionary hybrid working policy, which provides for a combination of working hours from your place of work and from your home in the UK. The current expectation for staff is to attend the office or non-home based location for 40-60% of the time over the accounting period.
DSIT does not normally offer full home working (i.e. working at home); but we do offer a variety of flexible working options (including occasionally working from home).

Things you need to know

The standard selection process for roles at GDS consists of:

• a simple application screening process - We only ask for a CV and cover letter of up to 750 words. Important tip - please ensure that your cover letter includes how you meet the skills and experience listed in the “person specification” section above
• a 60 minutevideo interview. As part of the interview process there will be a presentation task, details around the presentation task will be provided to shortlisted candidates.

Depending on how many applications we get, there might also be an extra stage before the video interview, for example a phone interview or a technical exercise.

Artificial Intelligence can be a useful tool to support your application, however, all examples and statements provided must be truthful, factually accurate and taken directly from your own experience. Where plagiarism has been identified (presenting the ideas and experiences of others, or generated by artificial intelligence, as your own) applications may be withdrawn and internal candidates may be subject to disciplinary action. Please see ourcandidate guidance for more information on appropriate and inappropriate use.

In the event we receive a high volume of applications, we will conduct the initial sift against the lead criteria which is:

• understand how to balance the needs of security against the need of users to access and use data to derive value

In the Civil Service, we useSuccess Profiles to evaluate your skills and ability. This gives us the best possible chance of finding the right person for the job, increases performance and improves diversity and inclusivity. We’ll be assessing your technical abilities, skills, experience and behaviours that are relevant to this role.

We’ll also be assessing your experience and specialist technical skills against the following skills defined in the Government Digital and Data Capability Framework for theLead Security Architect role:

• research and innovation

Recruitment Timeline

Sift completion: Thursday 16th October 2025

Candidates that do not pass the interview but have demonstrated an acceptable standard may be considered for similar roles at a lower grade.

A reserve list will be held for a period of 12 months, from which further appointments can be made.

Please note that this role requires SC clearance, which would normally need 5 years’ UK residency in the past 5 years. This is not an absolute requirement, but supplementary checks may be needed where individuals have not lived in the UK for that period. This may mean your security clearance (and therefore your appointment) will take longer or, in some cases, not be possible.

For meaningful checks to be carried out, you will need to have lived in the UK for a sufficient period of time, to enable appropriate checks to be carried out and produce a result which provides the required level of assurance. Whilst a lack of UK residency in itself is not necessarily a bar to a security clearance, and expectation of UK residency may range from 3 to 5 years. Failure to meet the residency requirements needed for the role may result in the withdrawal of provisional jobs offers.

Sponsorship

DSIT cannot offer Visa sponsorship to candidates through this campaign. DSIT holds a Visa sponsorship licence but this can only be used for certain roles and this campaign does not qualify.

Feedback will only be provided if you attend an interview or assessment.
