Senior iOS Engineer at Opal building the screen-time/focus iOS app used by millions, shipping features end to end, designing and analyzing AB tests, and improving AI-assisted dev workflows. Core stack: Swift, SwiftUI, UIKit, Combine. Remote within EU or UK, with periodic team meetups.
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
Why Opal
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.
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
