Why This Role and Why Now?

Screen time has become one of the defining issues of our era, affecting more than 5 billion people who carry a smartphone every day. Public awareness is rising fast, regulators are paying attention and Apple has made Screen Time a headline feature of its recent OS releases.

It is also a genuinely interesting moment to be an iOS engineer. The way apps get built has changed more in the last two years than in the previous ten. We want someone who is already living in that change, has built their own way of working with AI, and is improving it while maintaining ownership and a high bar for craft and excellence.

Here's why this is the right moment to join:

• A small team where your work is visible: You'll own real surfaces of an app that millions of people open every day.
• Craft is the culture: Polish is not a phase at the end of a project; it's the point.
• Room to lead: This role is scoped so that it can grow into technical leadership.
  
  

What You'll Be Doing

• Ship features and interactions end to end in the iOS app
• Bring your own ideas into the product, not just execute specs
• Design and analyse AB tests, and act on what the metrics say
• Improve our dev workflows, tooling and how the team works with AI
• Work directly with design and product in a flat, collaborative structure
• Support customers and stay close to what they're experiencing
  
  

What You Bring

• 5+ years building iOS apps, with work you can show live in the App Store
• Deep Swift, SwiftUI, UIKit and Combine. You are comfortable across the iOS toolchain
• An eye that catches the details other people ship past
• Your own workflows for working with AI, which you keep sharpening for yourself and your team
• Experience at an early-stage or fast-growing startup, where you owned more than your job title
• Comfort with ambiguity and a bias toward resolving it yourself
• A view on what makes a feature succeed, not just what makes it work
  
  

Bonus

• MacOS, WatchOS, WidgetKit and other Apple frameworks
• Experience training or fine-tuning models
• AB testing and analytics experience
• Apps of your own in the App Store, built because you wanted them to exist
• French
  
  

How to apply

The application takes about 15 minutes.

We ask for links to what you’ve shipped, a short video of something you built that you’re proud of, and how you work with AI. We watch every video.

If you want the thing you build to be the reason millions of people get their attention back, we’d like to see your work.

Compensation Range: £55K - £70K
