We are looking for a skilled Flutter Developer to join our growing team. In this role, you will be responsible for building and optimizing high-quality mobile applications using Flutter. You’ll work closely with cross-functional teams to deliver seamless, performant, and user-centric app experiences. If you're passionate about clean code, UI excellence, and continuous learning, we would love to hear from you.

What You'll Do:

• Responsible for the feature iteration, daily maintenance, and performance optimization of existing Flutter-based mobile applications.
• Participate in the mobile architectural evolution toward a "Native Shell + Web SPA" Hybrid setup, focusing on the construction and customization of core native containers (WebView).
• Implement highly efficient and secure cross-platform communication bridges (JSBridge) to ensure smooth integration between native OS capabilities and web applications.
• Target common Hybrid architecture bottlenecks, optimizing WebView loading speed, memory footprint, blank-page rates, and offline caching mechanisms to achieve native-like smoothness.
• Investigate and resolve cross-platform compatibility issues, low-level framework bugs, and system-level performance bottlenecks.

What We're Looking For:

• Bachelor’s degree in Computer Science, Computer Engineering, or related fields, with at least 3 years of professional mobile development experience.
• Proficient in at least one native platform — Android (Java/Kotlin) or iOS (Swift/Obj-C); profound understanding of mobile OS architectures, native rendering pipelines, and multithreading.
• Familiar with WebView container technologies; hands-on experience with Web-to-Native setups, micro-frontends, or Hybrid frameworks, with a solid understanding of underlying JSBridge mechanics.
• Strong command of Dart and Flutter core components, state management, lifecycles, and asynchronous programming, with the ability to quickly adapt and maintain current Flutter projects.
• Strong coding discipline and proficiency with Git for version control.
• Possess exceptional logical thinking, strong implementation skills, and a supportive attitude towards architectural evolution and technological change.
• Proficiency in both English and Mandarin, as you will collaborate with Chinese vendors.
• The role is based fully onsite, requiring your presence in the office.
