Sr Software Engineer - Mobile (React Native) at Playlist

Job description

About the Company: At Playlist, life's richest moments happen when people step away from screens to move, connect, explore, and play. We're building the definitive platform for intentional living, connecting people with inspiring experiences in fitness, wellness, and beyond. With popular brands like Mindbody and ClassPass, Playlist empowers businesses and individuals, making it effortless for aspirations to become actions. Join us in reshaping technology's role to foster meaningful, real-world connections. The Role You'll Play You'll build and evolve cross-platform mobile experiences at Playlist with React Native, shipping customer-facing features to iOS and Android across our consumer apps, from the interface down through networking and on-device data layers. You'll partner closely with Product, Design, and QA to take ideas from concept to production with high quality, reliability, and strong UX. You'll also operate at the edge of what's possible by leveraging AI (LLMs and agentic tooling) to accelerate delivery, improve quality, and push product capabilities forward. Partner with Product and Design to deliver features from ideation through App Store and Play Store release, iterating based on feedback and outcomes Own mobile features end-to-end across iOS and Android: UI, state and view logic, client networking, local persistence, and production rollout Build polished, accessible interfaces in React Native with a strong focus on performance, responsiveness, and UX quality on both platforms Design and integrate client-side networking against GraphQL/REST APIs, collaborating on schemas, contracts, authentication, and authorization Build reliable data flows on device: persistence, caching, background tasks, offline support, and sync Drive engineering excellence and operational health through automated testing, thoughtful code reviews, and strong crash reporting and observability, strengthening logging, error handling, resilience, and release readiness while identifying risks early Use AI effectively to move faster without sacrificing correctness: AI-assisted debugging, test generation, accessibility checks, refactors, and design/UX iteration Help foster a collaborative team culture that values autonomy, accountability, and impact What We're Looking For 5+ years building and shipping cross-platform mobile applications with React Native for large-scale consumer or SaaS products Strong proficiency with TypeScript and JavaScript , including strong fundamentals in the language and ecosystem Deep experience with modern React Native, including the New Architecture (Fabric, TurboModules, JSI) and the Hermes engine, plus core React patterns (hooks, composition, state management, render performance) Experience with the Expo toolchain (Expo Router, EAS Build/Submit/Update) or comparable bare-workflow and native build setups Solid experience shipping to both iOS and Android , including an understanding of platform differences and when to drop down to native code Comfort writing or maintaining native modules and bridging to native code (Swift/Objective-C, Kotlin/Java) when the situation calls for it Experience consuming GraphQL APIs (schema-driven development, client caching, pagination patterns) and/or well-designed REST APIs, including client data-fetching patterns (e.g., TanStack Query) Solid understanding of on-device persistence (e.g., AsyncStorage, MMKV, SQLite, WatermelonDB, or Realm), offline-first patterns, and networked-client fundamentals (timeouts/retries, idempotency, offline handling, graceful degradation) Familiarity with app architecture patterns (MVVM, TCA, or similar) and modular, testable codebases Solid debugging skills; comfortable using Xcode Instruments (Time Profiler, Allocations, Leaks) and the Xcode debugger Experience with testing across the stack: unit, integration, and UI (e.g., XCTest, XCUITest, snapshot testing) Experience with the release pipeline: App Store Connect, TestFlight, code signing, and provisioning Clear communicator who collaborates effectively across roles and working styles AI-native builder mindset with strong ownership and judgment: leverage AI to amplify output and quality, and bring (or quickly build) experience with AI-adjacent systems like evals, guardrails, prompt/tool design, and agentic workflows Tools and systems This role is cross-platform mobile with React Native, with ownership across product experiences, client services, and on-device data. You do not need to have used every tool here, but you should be comfortable learning new technologies and choosing the right approach for the problem.
