## Job description

We're looking for a Senior Android Engineer to build the app that helps millions of people take their attention back. Location: Remote, European Timezone (CET +/- 3h) with bi-annual global meetups + one 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 with 10M+ users. Android is rated 4.6 on the Play Store and climbing fast; our iOS app is an Apple Design Award finalist rated 4.8/5 across 60k+ reviews. That is the craft bar, and Android is where you get to set it. 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 both Google and Apple have made digital wellbeing a headline feature of their recent OS releases. Android is the newest part of Opal and the one with the most room in it. The app is early and not yet at parity with iOS — and Android is the larger platform globally, so we expect it to grow very fast as it catches up. You would be joining while the foundations are still being poured, with real influence over the architecture, the quality bar and what gets built first. It is also a genuinely interesting moment to be an Android 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 of the Android platform.

## What You'll Be Doing

- Ship features and interactions end to end in the Android app
- Close the gap with iOS and then take Android past it
- Bring your own ideas into the product, not just execute specs
- Design and analyse AB tests, and act on what the metrics say
- Own our Play Store releases, rollouts and policy compliance
- 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 Android apps, with work you can show live in the Play Store
- Deep Kotlin, Jetpack Compose, Gradle, coroutines and Flow. You are comfortable across the Android 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:

- The platform surfaces productivity apps depend on: permissions, overlays, accessibility services, usage stats, foreground services, background work and notifications
- Health Connect, Google Fit or similar health and wellbeing platforms
- Wear OS, widgets (Glance) and other surfaces beyond the phone app
- Experience training or fine-tuning models
- AB testing and analytics experience
- Play Console release management, CI and Firebase
- Apps of your own in the Play 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.
