İşler Teknoloji · Istanbul/Ankara · Full-time



We’re looking for a Senior Mobile Engineer who doesn’t just ship features, but understands how mobile systems actually work under the hood. You’ll work on high-scale mobile applications where JS, UI, and native layers intersect, and take ownership from first brainstorming session to production releases.



What You’ll Do

Own new and existing mobile projects from idea to App Store / Play Store release
Architect and build scalable features using React Native (New Architecture)
Write and maintain native modules (Swift / Kotlin) when needed
Optimize performance across JS thread, UI thread, and native layers
Identify and fix bottlenecks in rendering, memory, and startup time
Own CI/CD pipelines and App Store / Play Store release processes end-to-end
Collaborate with backend, design, and product in a fast-paced environment
Mentor mid-level engineers and contribute to technical decisions




What We’re Looking For

4+ years of mobile development experience
Deep understanding of React Native internals (bridge, threads, rendering)
Solid fundamentals in concurrency, parallelism, and threading
Experience writing native modules and platform-specific integrations
Proven ownership of CI/CD pipelines (Fastlane, GitHub Actions, Bitrise, etc.)
Experience profiling and optimizing render performance, memory, and startup time
Ability to explain trade-offs and make pragmatic engineering decisions




Tech Stack

React Native · JSI / Fabric · Swift · Kotlin · TypeScript · Fastlane · GitHub Actions · Firebase · Expo / EAS



Nice to Have

Flutter experience in production
App security & obfuscation




What We Offer

Real ownership — from architecture to production
Hybrid work setup in Istanbul
A strong team that pushes each other
Clear growth path toward tech lead or architect roles
