Mô tả công việc
DatVietVAC Group Holdings is looking for a Senior AI Native Engineer (React, Next.js, Flutter) to build web and mobile applications for our Fan Commerce Platform. You will develop web applications using React and Next.js and cross-platform mobile applications using Flutter for Android and iOS. This role follows an AI-native development approach, using coding agents and AI-assisted tools to accelerate delivery while maintaining high standards of code quality, security, performance, and maintainability in production. 1. Web and Mobile Application Development Build and maintain web applications using React, Next.js, and TypeScript. Develop cross-platform mobile applications using Flutter and Dart for Android and iOS. Deliver product features from UI/UX designs and product requirements through development, testing, release, and production support. Translate product requirements and designs into well-structured, testable, and production-ready code. Develop core user journeys across web and mobile, ensuring a consistent experience across platforms. Build responsive, accessible, and high-performing interfaces for different devices and network conditions. Optimize application performance, stability, loading time, and overall user experience. 2. AI-native and Coding Agent Development Use coding agents and AI-assisted development tools such as Cursor, GitHub Copilot, Claude Code, or equivalent solutions for code generation, refactoring, debugging, documentation, and repetitive engineering tasks. Design effective prompts, context, rules, and development workflows so that coding agents produce code aligned with product requirements, project architecture, and engineering conventions. Review, test, correct, and improve AI-generated code before merging or releasing it. Identify security, performance, maintainability, and architectural risks in AI-generated code. Balance development speed with code quality, testing coverage, maintainability, and long-term product stability. Evaluate new AI-assisted engineering tools and recommend practical applications for the development team. 3. System Integration and Product Quality Integrate web and mobile applications with backend services through REST or gRPC APIs. Implement authentication, authorization, state management, error handling, and end-to-end data flows. Write and maintain unit, integration, and end-to-end tests for core product journeys. Debug application issues and identify root causes across frontend, mobile, API, and integration layers. Participate in code reviews, CI/CD pipelines, release processes, and production troubleshooting. Ensure stable user experiences across supported browsers, operating systems, devices, and screen sizes. Collaborate with QC Engineers to define test scenarios and resolve issues before release. 4. Engineering Standards and Collaboration Develop and share best practices, reusable prompts, templates, and guidelines for coding-agent-assisted development. Contribute to frontend and mobile architecture, coding standards, reusable components, and shared libraries. Collaborate closely with Product Owners, UX/UI Designers, Backend Engineers, QC Engineers, and SRE/DevOps Engineers throughout the product development lifecycle. Communicate technical decisions, risks, dependencies, and trade-offs clearly to relevant stakeholders. Mentor team members on the effective and responsible use of coding agents. Continuously improve development workflows, code quality, engineering productivity, and release efficiency.
