Senior iOS developer


Design and Development
United Kingdom - Bristol Office

About the role

We are on the lookout for iOS developers to join our mobile app team at Dyson. Communication, collaboration, self-evaluation, and a desire to improve are second nature to you, and you value good engineering practises. You understand the need to deliver robust, testable code balanced against the need to deliver fast.

Our Tech:

Our iOS app is written in Swift and uses the MVVM pattern with [1] Coordinators. We have multiple modules to separate functionality and reuse common code, managed along with our external dependencies using Cocoapods.

Since almost everything that happens within our app is asynchronous, we use [2] RxSwift extensively to capture, combine and manage event streams, and also to bind the UI layer.

We write our unit tests with XCTest and RxTest, and we use XCUITest for automated UI testing.

What you’ll be doing:

  • Working with your fellow developers to contribute to features and improvements to our Dyson Link app, ensuring they are tested, robust and scalable
  • Working with colleagues from other disciplines, including test engineers, product owners, Scrum Masters, UX/UI designers, and software engineers in our cloud and embedded teams
  • Sharing knowledge within the app team to develop your skills and competencies and those of your teammates
  • Identifying new technologies, tools and approaches to help continually improve standards and quality

About you

  • You’re interested in how technology can improve the environments people live in
  • You’re a collaborative person that believes in the Agile principles and how they can help empowered teams deliver the best software
  • You’ve contributed quality code to iOS apps that have delighted their users
  • You’re passionate about learning new things and sharing those things with others
  • You get satisfaction from solving real-world problems with well-crafted software

About us

At Dyson we are focused on solving the problems that others have ignored; solving them first by using our technology and ingenuity. More and more often this requires complicated software solutions to bring many of the fantastic features Dyson products offer to their users. 

This means that our software engineers are challenged every day. We have to crack problems that aren’t easy to crack, and we have to meet deadlines that are always challenging. This means we must collaborate with each other frequently, and we have world class campuses available where this collaborative work can take place. We also understand that engineers might need focus time, time to work without interruptions, in a quiet environment and with little to no distractions - at home. That is why we allow our software engineers, who are able to work effectively from home, to request to do so for up to 2 days a week.  This hybrid way of working seems to balance well and provides the best of the two worlds:

  • It provides focus time so hard to crack problems can be solved
  • We understand our software teams are adept at collaborative working from different locations
  • You can still collaborate with your colleagues at one of our great campuses with fantastic facilities

We own and develop the Dyson Link Smart home app, which is at the forefront of Dyson's IoT experience. We are proud of what we have built so far; we have an App Store and Google Play rating of 4.5 and 4.3 stars respectively, we have more than 1 million active users worldwide and our IoT platform has over 3 million connected Dyson machines. We have huge ambition to grow this platform and as we connect more machines from more categories the challenge is significant.

Our Team:

There are 5 app teams, located in the UK and Singapore, each with up to 6 mobile developers and 3 test automation engineers, plus a scrum master and product owner. We all come from a variety of educational backgrounds and experience levels; not all of us are computer science graduates. We believe that teams composed of people from diverse backgrounds are more successful and innovative.

Our teams have the autonomy to manage their own work using Scrum or Kanban frameworks, each honing their ways of working through regular retrospectives and knowledge sharing. We all share a commitment to creating high-quality code, and engineers choose to follow practices such as pair programming, mobbing, and test-driven development. We also regularly share our knowledge and interests peer-to-peer through ‘community meetings’, which have led to the adoption of new technologies and improved cross-team collaboration.

We often need to interact with people from different parts of the business, such as embedded software and the cloud teams, so we plan in 5-sprint ‘increments’, based on the best bits of the [1] Scaled Agile Framework. This gives us more visibility of upcoming work while remaining responsive and allows us to collaborate effectively with other teams within our 11,000-person organisation.

Mutual trust and respect between team members is important to build a supportive environment where people can do their best work. Our teams understand themselves well enough to make decisions about how they work; everyone’s contribution is vital.

Besides being software professionals, we are also people who enjoy playing online or board games, heading out to lunchtime yoga classes, recording our latest run on Strava or just catching up over coffee. The last year has been a challenge, but we have maintained and strengthened our culture while working through the various lockdowns with virtual events, an informal team newsletter and an empathetic attitude to the needs of individuals.



Dyson is an equal opportunity employer. We know that great minds don’t think alike, and it takes all kinds of minds to make our technology so unique. We welcome applications from all backgrounds and employment decisions are made without regard to race, colour, religion, national or ethnic origin, sex, sexual orientation, gender identity or expression, age, disability, protected veteran status or other any other dimension of diversity.
