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
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
Location: Remote (EU or UK), with bi-annual global meetups and 1 team meetup
Mission-driven impact: We are on a mission to help 1 billion people focus better every day. Our community has saved 500M+ hours and counting.
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.
Growth & recognition: A top-30 US productivity app, Apple Design Award finalist, 4.8/5 across 60k+ reviews. Competitive compensation and early equity.
Well-supported: Backed by world-class investors and the founders of Pinterest, Snapchat and Revolut.
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.
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.
