Our mission at Duolingo is to develop the best education in the world and make it universally available. It’s a big mission, and that’s where you come in! At Duolingo, you’ll join a team that cares about finding innovative solutions to complex technical problems , running countless experiments (300+ at a time!) with our massive user base to make data-driven decisions, and educating our users and employees alike. You’ll have limitless learning opportunities, mentorship and collaboration with world-class minds, and a variety of projects with large scopes — while doing work that’s both fun and meaningful. Join our life-changing mission to develop education for our half a billion (and growing!) learners around the world. About the Role... We are hiring for Android Engineers at various levels, and below you can find more information about the teams we're hiring for: Subscriber Conversion Team: The Subscriber Conversion team owns the surfaces that turn learners into subscribers and keep them subscribed including in-app hooks and paywalls, the purchase flow, pricing and packaging, payments, and subscription partnerships. The team is highly experimental, running a steady stream of A/B tests across iOS, Android, backend, and web, and balances quick optimizations on high-traffic surfaces with larger bets like new tiers and partner offerings. In-App Purchases Team: The IAPs team owns Duolingo’s in-app purchase business: the gem economy, the shop, and avatar cosmetics and collectibles. You’ll build purchase flows and the systems behind them, then prove out what works through experimentation. Avatar cosmetics and collectibles are our new initiatives to drive DAU aligned monetization. Math Discovery: The Math Progress team builds the experiences that connect Duolingo's math lessons into a cohesive learning journey. We help learners find the right content by improving how they navigate topics, grades, and the course path, and we make their learning progress visible through m

Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way. The Community You Will Join: Guest & Host Technology builds the end-to-end experience that connects people around the world: from the first search to the moment a trip becomes a memory. Because that experience lives natively on iOS and Android, with no cross-platform framework in between, we're looking for engineers who move fluidly across both platforms to keep architecture, performance, and product quality coherent everywhere our guests and hosts show up. The Difference You Will Make: We're looking for a Senior Software Engineer who can operate as a true dual-platform native engineer — someone with solid, current fluency in both iOS and Android. You'll own features end-to-end across both apps, and you'll be one of the people trusted to make architectural calls that need to hold up identically on Swift and Kotlin. You'll write production code on both platforms, and you'll also be expected to think beyond any single feature: flagging where our two native codebases are drifting apart, where a shared contract (like our GraphQL client layer) needs to evolve, and helping less experienced engineers ramp into dual-platform work. A Typical Day: Design and ship features across our iOS (Swift) and Android (Kotlin) native codebases, often the same initiative, shipped in parallel on both platforms Partner with design and product to translate one product spec into two platform-idiomatic implementations, rather than porting one platform's UI onto the other Uphold architecture, performance, and app-size standards that apply equally to both platforms Weigh in on shared client contracts (schema, logging
