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

Selection process details

The standard selection process for roles at GDS consists of:

  • a simple application screening process - We only ask for a CV and responses to three questions. Important tip - please ensure that your CV includes how you meet the skills and experience listed in the “person specification” section above
  • a 30 minute phone screen
  • a 95 or 105 minute technical interview and civil service behavioural interview (conducted over video conferencing)

Whilst we value the use of AI technology to enhance our daily work, we also value the personal touch and urge applicants to write responses without the use of AI to emphasise their own unique experiences.

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.

In the Civil Service, we use Success 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.

For this role we’ll be assessing you against the following Civil Service Behaviours:

  • working together
  • changing and improving
  • making effective decisions

We’ll also be assessing your experience and specialist technical skills against the following skills defined in the Digital, Data and Technology Profession Capability Framework for the DevOps engineer role:

  • Availability and capacity management
  • Development process optimisation
  • Information security
  • Modern development standards
  • Programming and build (software engineering)
  • Service support
  • Systems design
  • Systems integration

Recruitment Timelines

Role closes: Tuesday 8th April

Sift completion: Friday 11th April

Phone Interviews: starting Monday 14th April

Panel interviews: starting Tuesday 22nd April 

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.

The Civil Service is committed to attract, retain and invest in talent wherever it is found. To learn more please see the Civil Service People Plan and the Civil Service D&I Strategy.

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.

Other information

In January 2025, it was announced that the Government Digital Service (GDS) will move to the Department for Science, Innovation and Technology (DSIT) as a part of a machinery of government change. This change aims to bring together the digital transformation of public services into one central department, presenting exciting opportunities and positioning DSIT to lead the government’s digital agenda.

This role is in scope to transfer to DSIT when the machinery of government change takes place.  As a result,  if you are successful and appointed by Cabinet Office to this role before 1st June 2025, your role will transfer from Cabinet Office to DSIT at the time of the relevant machinery of government change taking place,.  If your start date is after 1 June 2025, you will be appointed direct to DSIT and your appointment will be unaffected by the machinery of government change.  We are currently consulting with our Trade Unions on which policies, terms and conditions will apply on transfer.  The statement of changes applied to all other Cabinet Office staff will also apply to you if you are successful.”

We encourage you to apply and look forward to reviewing your application. We will keep you updated throughout the process.

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.
