We are Government Digital and Data Candidate Information Pack V3 - 1

Using your experience and skills, you may be asked to work on our ‘Flood services’ - developing government digital services, to share information about current and future flood risk with the public. It could be your job to ensure that they are accessible to all, especially in times of severe weather!

Alternatively, you could be involved with our Farming and Countryside Programme, which is about delivering services to make farming sustainable, increase biodiversity, promote high animal health and welfare standards, and contribute to the Government’s Net Zero commitment, ensuring public money for public good.

A wide range of other projects requires us to maintain and develop externally facing digital services and internal applications. As part of a multidisciplinary team, you will have responsibility for ‘owning’ the functionality that you develop.

If you would like to join us in building great solutions for Defra and our Arm’s Length Bodies, then this could be the job for you. As a Lead Developer, you will also play a key role in shaping modern development practices across teams, including the adoption of AI‑assisted coding tools such as GitHub Copilot. You’ll use these tools to support faster delivery, improved code quality and better outcomes for users, whilst ensuring that strong engineering judgement, code review, testing and security remain central.

You will review colleagues design and development thinking, helping teams to make good technical decisions to select the most appropriate technologies. You will lead the integration of multiple systems and services, collaborate with senior stakeholders and suppliers, and provide direction and constructive challenge to ensure that solutions are secure, maintainable and sustainable.

This is an opportunity to be part of an organisation actively modernising how software is built in government, combining strong engineering fundamentals with the responsible use of new tooling, including AI, to improve delivery at scale.

We use a modern, cloud‑based technology stack, and follow continuous delivery and DevSecOps best practice.

Our current technologies include:

• Runtime & web development: Node.js, HAPI
• API development: REST, OpenAPI
• Databases & caching: PostgreSQL, MongoDB, Redis
• Unit testing: Jest, Lab
• Source control: Git, GitHub
• Cloud hosting: Azure and AWS
• Containerisation & orchestration: Docker, Kubernetes, ECS
• CI/CD & release management: Azure DevOps, Jenkins, GitHub Actions
• Work management: Jira, Azure DevOps
• Developer productivity tools: AI assisted coding tools such as GitHub Copilot (where appropriate), alongside established code review and quality controls

Location

As part of the pre-employment process for this post, successful candidate(s) will be able to agree a contractual workplace from those locations listed in this advert. The agreed contractual workplace is then the substantive and permanent place of work for the successful candidate(s).

Where the location is ‘National’ the successful appointee should discuss and agree an appropriate contractual location in line with both Defra’s location policy and site capacity, prior to proceeding with pre-employment processes.

The agreed amount of time spent at a workplace for this post will reflect the requirement for Civil Servants to spend at least 60% of their working time in an organisation workplace with the option to work the remaining time flexibly from home. Working time spent at a workplace may include time spent at other organisational locations including field-based operational locations, together with supplier, customer or partner locations. This is a non-contractual agreement which is consistent with common Civil Service expectations.

Travel costs to non-contractual workplaces will be subject to departmental travel and subsistence policies. Travel costs to contractual workplaces are the responsibility of the employee.

The successful candidate is required to carry out all their duties from a UK location, and cannot do so from an overseas location at any time.

Defra includes the core department, APHA, RPA, Cefas and VMD.

Further Information

Reserve list

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

Childcare Vouchers

Any move to DEFRA from another employer will mean you can no longer access childcare vouchers. This includes moves between government departments. You may however be eligible for other government schemes, including Tax Free Childcare; for further information visit the Childcare Choices website.

Near miss

Candidates who are judged to be a near miss at interview may be considered for other positions in Defra which may be at a lower grade, but have a potential skills match.

Merit Lists

Where more than one location is advertised, candidates will be posted in merit order by location. You will be asked to state your location preference on your application.

Salary

New entrants to the Civil Service are expected to start on the minimum of the pay band. The internal roles rules apply to existing Civil Servants, i.e. level transfers move on current salary or the pay range minimum, transfers on promotion move to new pay range minimum or receive 10% increase. Either case is determined by whichever is the highest.

Reasonable adjustment

If a person with disabilities is put at a substantial disadvantage compared to a non-disabled person, we have a duty to make reasonable changes to our processes.

If you need a change to be made so that you can make your application, you should:

Contact Government Recruitment Service via defrarecruitment.grs@cabinetoffice.gov.uk as soon as possible before the closing date to discuss your needs.

Complete the “Assistance required” section in the “Additional requirements” page of your application form to tell us what changes or help you might need further on in the recruitment process. For instance, you may need wheelchair access at interview, or if you’re deaf, a Language Service Professional.

Accessibility

If you are experiencing accessibility problems with any attachments on this advert, please contact the email address in the 'contact point for applicants' section.

Criminal Record Check

If successful and transferring from another Government Department a criminal record check may be carried out.

In order to process applications without delay, we will be sending a Criminal Record Check to Disclosure and Barring Service on your behalf.

However, we recognise in exceptional circumstances some candidates will want to send their completed forms direct. If you will be doing this, please advise Government Recruitment Service of your intention by emailing Pre-EmploymentChecks.grs@cabinetoffice.gov.uk stating the job reference number in the subject heading.

Internal Fraud Database Check

Applicants who are successful at interview will be, as part of pre-employment screening, subject to a check on the Internal Fraud Database (IFD). This check will provide information about employees who have been dismissed for fraud or dishonesty offences. This check also applies to employees who resign or otherwise leave before being dismissed for fraud or dishonesty had their employment continued. Any applicant’s details held on the IFD will be refused employment.

A candidate is not eligible to apply for a role within the Civil Service if the application is made within a 5 year period following a dismissal for carrying out internal fraud against government.

Higher Security Clearance

All of these posts require the successful candidate to hold SC security clearance.
