Job Responsibilities

Lead the design of front-end technical solutions for complex business scenarios, take charge of the architectural design and implementation of core modules/systems, and ensure the scalability and stability of the system.

Deeply optimize the performance of the React technology stack, and solve performance bottlenecks in large-scale applications (such as rendering optimization, bundle size optimization, first-screen loading optimization, etc.).

Promote the upgrade of the front-end engineering system, including build tool optimization, implementation of automated testing (Jest/Cypress), and formulation and promotion of technical specifications.

Lead the development of map-related core functions, such as large-scale POI data visualization, real-time trajectory display, geospatial analysis, etc., connect with map SDKs, and solve complex map interaction problems.

Be responsible for cross-end architecture design and technology selection, build a unified multi-end solution based on frameworks such as React Native/Taro, and improve development efficiency and experience consistency.

Guide junior developers, participate in code reviews, and promote the improvement of the team's technical capabilities.

Track cutting-edge front-end technologies (such as SSR/SSG, micro-frontend, WebAssembly, etc.) and implement them in combination with business scenarios.

Requirements

Bachelor's degree or above in Computer Science or related majors, with more than 5 years of front-end development experience and at least 2 years of experience leading development with the React technology stack. Priority is given to candidates with architectural design experience in large-scale Web applications (DAU 100,000+).

Must have a deep understanding of React's underlying principles (Virtual DOM, Fiber architecture, Diff algorithm, etc.), and be proficient in state management, routing design, and complex component communication solutions.

Proficient in front-end performance optimization methodologies, with successful cases of performance tuning for large-scale applications, and familiar with debugging tools such as Chrome DevTools.

Familiar with the entire front-end engineering process, able to independently build front-end scaffolding and design modular architectures. Priority is given to candidates with micro-frontend/cross-end architecture design experience.

Preferred Qualifications:

Led the development of map-related projects, extensively used tools such as Mapbox GL JS, Baidu/Google Maps SDK, and solved problems such as large-scale geospatial data rendering and complex map interactions.

Led the from-scratch construction of cross-end projects (React Native/Taro) and can solve core issues such as cross-end compatibility and performance loss.

Possess technical foresight, able to proactively identify technical risks and propose solutions. Priority is given to candidates with team management or technical mentoring experience.

Excellent communication and coordination skills as well as project promotion capabilities, able to balance technical and business objectives in complex business scenarios.
