Frontend Developer

Responsibilities

• Lead architectural design, core module development, and continuous iteration of the company's Flutter-based cross-platform mobile applications, ensuring exceptional user experience and high stability.
• Responsible for the development and maintenance of the company's web platforms and admin systems, ensuring cross-browser compatibility and responsive design.
• Continuously optimize both mobile and frontend architectures for peak performance, robust security (anti-reverse engineering/anti-debugging), and seamless maintainability.
• Contribute to Flutter engineering and modularization standards, build reusable Widget libraries, and drive scalable development practices across the team.
• Proactively identify product gaps, UX friction points, and technical risks across both App and Web platforms, proposing and implementing actionable solutions.
• Explore and integrate AI-assisted workflows and modern development tooling into coding and delivery pipelines to boost velocity and quality.

Requirements

• Proficient in Dart with 3+ years of hands-on experience in production-level Flutter cross-platform mobile development and app store deployment.
• Deep understanding of Flutter core principles (e.g., Widget lifecycle, custom painting, animations, memory management) and state management solutions (e.g., Bloc, Provider, or Riverpod).
• Familiar with Flutter-to-native communication via MethodChannel; hands-on experience with native iOS (Swift/Obj-C) or Android (Kotlin/Java) is highly preferred.
• 3+ years of frontend development experience, proficient in the React ecosystem (Redux / Mobx / Zustand, Next.js), TypeScript, ES6+, and CSS3.
• Solid experience with SSR applications, with a deep understanding of web rendering lifecycles, hydration mechanisms, and web performance tuning.
• Extensive experience in mobile and frontend troubleshooting and problem diagnosis (e.g., app crash analysis, memory leaks, production outages, root-cause analysis).
• Hands-on experience in writing robust automated tests, including Unit tests, UI tests, and End-to-End (E2E) tests across both Web and App environments.
• Thrive in a fast-paced, highly autonomous environment with the ability to think big and look beyond just implementation details.

Will be advantages

• Familiar with mobile automation deployment pipelines and delivery workflows (e.g., GitHub Actions, CI/CD pipeline design).
• Experience in AI Agent development or successful deployment of AI applications in real-world business scenarios.
• Experience in Fintech or high-security applications, with knowledge of mobile code obfuscation, sensitive string protection, and cryptographic techniques.
