Full-Stack Developer (AI Agent)

About the role

We are looking for a Full-Stack Developer to design, develop, and maintain scalable web applications across both frontend and backend, with deep involvement in building AI-powered applications. You will leverage AI coding tools to boost productivity while being able to review and refine AI-generated code, working on cutting-edge areas such as LLM integrations, AI Agents, chatbots, and workflow automation.

Key responsibilities

• Full-Stack Development: design, develop, and maintain scalable web applications across frontend and backend
• Backend Development: build and optimize backend systems using PHP (Hyperf / Laravel or other MVC frameworks), MySQL, and Redis; may also contribute to Java, Python, Go, or Node.js stacks for APIs and business logic
• Frontend Development: develop responsive, user-friendly interfaces using modern JavaScript frameworks (React, Vue.js, Next.js)
• API Development: design, develop, and integrate RESTful APIs and third-party services
• AI Application Development: develop and deploy AI-powered applications including LLM integrations, AI Agents, chatbots, workflow automation, and intelligent assistants
• AI Service Integration: integrate AI services such as OpenAI, Anthropic Claude, Google Gemini, or other LLMs
• AI-Assisted Development: proficiently use AI coding tools (GitHub Copilot, Cursor, Claude) to write, complete, and debug code — quickly understanding requirements, generating code skeletons, and shipping them
• Database Operations: perform database design and CRUD (MySQL, Redis, MongoDB); write and optimize SQL; improve database efficiency, scalability, and security
• Code Quality: review, test, and correct AI-generated code — understanding its principles rather than copying blindly — keeping code clean, readable, maintainable, and runnable; follow best practices and participate in code reviews
• Bug Fixing & Testing: locate and fix defects across the full stack; write basic unit tests; support integration and self-testing

Requirements

• Bachelor's degree or above in Computer Science, Software Engineering, or a related field

• Full-stack development experience; command of at least one backend language and one frontend framework

Strong experience with:

• PHP (Hyperf / Laravel or other MVC frameworks)

• MySQL, Redis

• JavaScript, HTML5, CSS3

• Modern frontend frameworks such as React, Vue.js, or Next.js

• RESTful API development, Git version control

• Basic database and networking knowledge

• Familiar with or willing to deeply use AI coding tools (Copilot / Cursor); able to read and judge the correctness of AI-generated code rather than copy it blindly

• Strong analytical and problem-solving skills; fast learner, responsible; able to work independently and collaborate effectively

Preferred / Plus

• Experience with Nginx, Linux, and Docker

• Experience integrating AI APIs such as OpenAI, Claude, Gemini, or similar LLM platforms

• Knowledge of AI Agent frameworks (LangChain, LangGraph, CrewAI, AutoGen, OpenAI Agents SDK, MCP)

• Experience with RAG (Retrieval-Augmented Generation), vector databases, prompt engineering, function calling, and AI workflow automation is preferred
