Senior Android Engineer

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…
