The Government Digital Service is leading the digital transformation of government, making public services digital by default, and simpler, clearer and faster to use. 


This is what we do and this is what we create. You can keep up to date with what we are doing at the Technology at GDS blog.


Help us make government better.


The projects 

We are looking for Senior Developers of all experiences and backgrounds who can work across a range of projects. During the application process we will take your skills and any preference you express on board and aim to match you to an appropriate project. GDS staff move between projects on need and request. Some brief information on projects (details can be found in the attached Job description) 

GOV.UK - is the place to find government information and services. It’s designed to make dealing with government simpler, clearer and faster. It's a microservices based architecture, primarily based upon Ruby on Rails, with elastic search, MongoDB, PostGres and a variety of other technologies. 

GOV.UK Verify s the new way to prove who you are online. It is a service based architecture, primarily based upon Java. 

Digital Marketplace is helping those transforming public services by making it simpler, clearer and faster for them to buy what they need. It is built in Python, based on an Amazon AWS stack. 

Government Platform as a Service (PaaS) is a new vision for digital government; a common core infrastructure of shared digital systems, technology and processes on which it’s easy to build brilliant, user-centric government services. We select and use an appropriate technology stack for the problem at hand. 

The role 

You’ll share the responsibility for the digital transformation of government. You’ll ensure high quality code is delivered in line with project goals and delivery cycles. You’ll thrive using agile methods and enjoy working openly, collaboratively and as part of a multidisciplinary team focused on one or more projects. Above all, you’ll want to make government better, which may sometimes involve challenging the status quo. 

To learn more about what Senior Developers do in government please review the DDaT Capability framework


All GDS Developers will:

  • build RESTful web services to serve a variety of citizen and government needs, taking responsibility for the quality of code you produce 
  • implement toolkits and APIs for purposes such as integration, performance optimisation, security and scalability 
  • build automated tests to support our continuous deployment environment 
  • share knowledge of tools and techniques with your wider team, both developers and non-developers 
    act as a digital ambassador across government, supporting recruitment, identifying good practices for GDS to adopt and sharing experiences, eg through blog posts, tech talks at conferences etc. 
  • participate in our in-house (2nd line) support, and potentially the out-of-hours support rota (evenings and weekends approximately once every 8 weeks) - you’ll be paid an allowance, and a further hourly payment, for any duties you perform when on call 
  • be involved in helping recruit developers and, where appropriate, helping sift and interview 


For the Senior Developer role, it is essential that you have the above as well as the following: 


  • ability to quickly research and learn new programming tools and techniques 
  • familiarity with working practices such as TDD, continuous integration, continuous delivery and DevOps 
  • experience in management, helping colleagues with their career development and coaching more junior staff members 


The basic skills we would expect a Developer to have: 

  • experience in back-end development, with detailed knowledge of ideally one of Ruby, Java, Python, Javascript, Go or scala
  • understanding of software design principles 
    ability to quickly research and learn new programming tools and techniques 
  • a systematic approach to solving problems 
  • experience of using testing to validate solutions 
  • understanding of agile environments and version control 
  • basic understanding about web security 
  • an awareness of technologies used for web applications, e.g databases, backups, CDNs and search, and of Unix-like operating systems, eg. Linux and/or Mac OS experience of working on, or with web technologies  

EU Exit Project

There is a high demand for Senior Developers to work on priority EU exit digital programmes across the Civil Service. Senior Developers employed by GDS may be temporarily deployed to other government departments to support this work.

Deployment is an opportunity to work on some of the most important and interesting programmes in government. It offers valuable experience of fast paced delivery, cross departmental collaboration and holding an ambassadorial role for GDS’s transformational approach to public service. You will continue to be employed by GDS and can claim necessary expenses for travel or accommodation.  

If you have a preference for working on EU exit programmes please note this on your application. We will take this into account when deciding how to best deploy staff, although we cannot guarantee everyone will get their first preference.
