We're looking for a Senior iOS Engineer to build the app that helps millions of people take their attention back.

• Role Title: Senior iOS Engineer
• Team: Engineering

Location: Remote (EU or UK), with bi-annual global meetups and 1 team meetup

Ownership & flexibility: Structure your work to foster creativity and productivity.

Collaborative culture: A small, high-impact team that gathers bi-annually for meetups and learning. Nearly $1M in revenue per employee.

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

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.
