SeniorFull-StackMobileEngineer

SUMMARY Level is a learning technology company dedicated to helping students build real academic and life skills with confidence and joy. We combine proven curriculum principles with world class interactive design to make meaningful practice something students want to come back to, not something they struggle through. We support what teachers, schools, and parents are already doing by increasing student engagement with high quality, standards-aligned practice that reinforces classroom learning. As a Senior Full-Stack Mobile Engineer on the Platform team, you will own end-to-end slices of Level's mobile experience — from the iOS and Android clients through the API layer and into the services that power identity, onboarding, content delivery, and engagement on mobile devices. You'll write production native code on at least one mobile platform, work in cross-platform code where it makes sense, and design and implement the backend services that sit behind them. We are hiring senior engineers specifically because we want people who can move fluently across the whole stack and make sound trade-offs at every layer. Your work will directly impact how students experience Level on mobile, and how quickly the rest of the engineering organization can ship mobile-enabled features. WHAT YOU WILL DO Feature Development - Design, build, and ship user-facing mobile features end-to-end — native client work on iOS and/or Android, plus the backend services and APIs that power them. - Implement clean, readable, testable code that follows platform best practices on the client and Level's service conventions on the backend. - Take responsibility for features from initial design through release and ongoing maintenance. Architecture & Cross-Platform Decisions - Evolve module boundaries, navigation, state management, and offline behavior in the mobile clients. - Make sharp build-vs-share decisions between fully native code and cross-platform approaches (Kotlin Multiplatform, shared protobuf
