As a Developer or Senior Developer you can expect to have a central role in multidisciplinary teams building the future of government services. We are building in two main areas. Native iOS and Android applications power our identity proving service, allowing for a quick, easy and highly trusted way to prove your identity to government. We also building a new Wallet application, allowing users to take control of their credentials and interact with the next generation of government digital services.
You will have the autonomy to scope work and find a route to solutions, whilst enabling those around you to do the same. You will be given the space to hone a mastery and grow in the role, whilst sharing your existing experience with the engineering community. All whilst doing work that improves government services for millions of users across vital services.
You’ll join the GOV.UK One Login programme as a Senior iOS Developer.
You’ll build and maintain the GOV.UK One Login iOS app, as part of a multidisciplinary team. The app is written in Swift with UIKit, with support going back to iOS 15.
As a Mid or Senior iOS App Developer, you’ll:
- work as part of a multi-disciplinary agile team, getting involved with every part of the lifecycle of the application, from user research to releasing the application
- build accessible iOS apps, taking responsibility for the quality of code you produce
- build automated tests to maintain software quality
- share knowledge of tools and techniques with your wider team, both developers and non-developers
- support the live operation of the services we run, and participate in out-of-hours support rotas where necessary - 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
- provide technical leadership within team, advising and working with developers to identify the best solutions
- take responsibility for developing others, through line management and/or mentoring
- take responsibility for solving complex issues
You’ll share the responsibility for the digital transformation of the government. You’ll ensure high quality code is delivered in line with programme 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 services. Above all, you’ll want to make the government better, which may sometimes involve challenging the status quo.

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 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 30 minute telephone interview (may not be required depending on the volume of applicants)
- a 60 minute pair programming technical exercise - you'll work with a GDS engineer to solve a self-contained programming problem given to you in writing. You'll be asked to discuss the problem with the GDS engineer, devise a plan for solving it, and then to write code to solve the problem. As well as your programming and unit testing skills we'll be evaluating how you communicate and collaborate, and how you break down the problem. You'll use your own development environment for this (conducted over video conferencing)
- a 75 minute video interview
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:

Phone interviews: Tuesday 22nd July
Technical exercises: starting Tuesday 5th August 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.
