The Government Digital Service (GDS) is the digital centre of government. We are responsible for setting, leading and delivering the vision for a modern digital government.

Our priorities are to drive a modern digital government, by:

• joining up public sector services
• harnessing the power of AI for the public good
• strengthening and extending our digital and data public infrastructure
• elevating leadership and investing in talent
• funding for outcomes and procuring for growth and innovation
• committing to transparency and driving accountability

We are home to the Incubator for Artificial Intelligence (I.AI), the world-leading GOV.UK and at the forefront of coordinating the UK's geospatial strategy and activity. We lead the Government Digital and Data function and champion the work of digital teams across government.

We're part of the Department for Science, Innovation and Technology (DSIT) and employ more than 1,000 people all over the UK, with hubs in Manchester, London and Bristol.

The Government Digital Service is where talent translates into impact. From your first day, you'll be working with some of the world's most highly-skilled digital professionals, all contributing their knowledge to make change on a national scale.

Join us for rewarding work that makes a difference across the UK. You'll solve some of the nation's highest-priority digital challenges, helping millions of people access services they need.

This role is in the Office of the Government Chief Technology Officer (OCTO). We published the State of Digital Government report, own the Cloud First Policy, created the AI Playbook.

The Principal Technologists in GDS's Office of the Government CTO function exist to make building great technology easier in the UK Public Sector. In this role you can help central and local government, the NHS, Police, as well as 1,000+ agencies and other bodies. By setting strategies, principles, standards and identifying best practice, as well as supporting the adoption and embedding of these into the public sector, you'll help your 100,000+ digital and data colleagues in these organisations deliver transformational change.

Our Principal Technologists are currently focussed on Artificial Intelligence, Engineering Excellence, Cloud & Platforms, Technology Management and Digital Workplace, making these easier for organisations of all sizes. They create strategy and identify opportunities for these technologies for the UK Public Sector.

You will manage and mentor a Lead Technologist aligned to you and your team, who can support you when you need to rapidly deep-dive into a topic to achieve your team's outcomes.

As Principal Technologist you will be leading a team including lead technologists, engagement leads and a delivery manager to:

• Set a 10-year intent and strategy for the field you are aligned to, and gain endorsement for this
• Identify and develop existing principles, standards and best practice and promote them, or form and lead a group of technologists from across UK Public Sector to create these
• Work with vendors to maximise their offer to UK Public Sector, and with Government Commercial Function in commercial engagements with vendors
• Build a network of peers across UK Public Sector to regularly engage with
• Promote your work through content written for GOV.UK, speaking engagements and hosting community events
• Help upskill others across UK Public Sector in your specialist area

The above list of job duties is not exclusive or exhaustive and the post holder will be required to undertake such tasks as may reasonably be expected within the scope and grading of the post.

These roles have a scale and impact unlike many others: we are routinely involved in commercial engagements worth £billions, respond to pan-Government technology questions from ministers, and provide advice to other international governments.

Please don't let this sound intimidating; if you could see yourself in this role, we'd like to hear from you.

Person specification We're interested in people who:

• have experience setting a vision and leading digital and data change
• have experience designing and building technology and be able to use this to build credibility with others, evaluate proposals and decide an execution approach
• have experience engaging with suppliers/vendors both formally and informally
• are comfortable in creating written content and presenting to senior stakeholders, both technical (such as CTOs / CDOs across Government) and non-technical (including ministers and permanent secretaries)
• ensure learning is embedded in the way you approach your working week, and you should be keen to share your learning with those around you through coaching and mentoring
• are at the top skill levels in your Digital & Data specialism, most likely from the Architecture, Data, IT Operations or Software Development groups
• hold relevant industry certifications for your technical specialism.

Things you need to know The standard selection process for roles at GDS consists of:

• a simple application screening process - a CV and 2 application questions
• A Short video submission in response to a scenario' details will be shared to candidates that are successful at the application stage
• Finally a 60 minute video interview where you give examples in situation-task-action-result format

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 order to assist candidates with this role, we will be holding a virtual recruitment event on Friday 11th April at 1:00pm - 2:00pm to go through the role in more detail. If you are interested in joining this event please e-mail: and a member of the team will send you an invitation to the event.

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

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

• Describe a time when you used your technical background to set strategic priorities that an organisation or multiple organisations have adopted. Use "I" rather than "we" language, and you should use the STAR format. This question will be assessed based on the Civil Service Behaviour: Seeing the Bigger Picture

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.

We'll also be assessing your experience and specialist technical skills against the following skills defined in the Government Digital and Data Profession Capability Framework for the Principal Technical Architect role:

• Making and guiding decisions
• Communicating between the technical and non-technical
• Understanding the whole context
