​A closer look at real job descriptions—from responsibilities and tech stacks to projects and interviews. 🔍
​“AI Application Development Engineer,” also known as an LLM Application Engineer or Large Model Application Engineer, is becoming an increasingly popular career direction for developers in China. 🤖
​Yet when you browse job listings, you’ll find very different requirements. Some roles focus on integrating LLM APIs, while others require experience with RAG, AI Agents, MCP, private deployment, model evaluation, data security and cost optimisation.
​After reading dozens of job descriptions, many people still have the same questions:

• ​💼 What does this role actually involve day to day?
• ​🔄 How is it different from a traditional backend or algorithm engineer?
• ​🧠 What technical skills and project experience do companies really value?
• ​🛠️ If you already have software development experience, what else do you need to learn?
• ​📄 What kind of AI project can strengthen your resume and stand up to interview questions?

​In this livestream, we will break down representative AI application development job descriptions from the Chinese market. We’ll examine the role from four perspectives: responsibilities, technology stack, project experience and interview expectations.
​This is not a discussion of vague industry trends. We will focus on real job requirements and practical projects: what problems companies expect you to solve, what capabilities they are looking for, and how your existing experience can transfer into AI application development.

## ​🔍 What We’ll Discuss

1. ​What does an AI Application Development Engineer actually do?
   From business requirements and model integration to knowledge bases, AI features and production deployment.
2. ​What are real job descriptions asking for?
   A breakdown of responsibilities, technology stacks, experience requirements and project expectations.
3. ​Why is calling an LLM API not enough?
   The gap between a quick demo and a production-ready AI application—including evaluation, logging, security, reliability and cost.
4. ​What should you learn first: RAG, Agents, MCP, evaluation or deployment?
   Build a structured capability map instead of following isolated buzzwords.
5. ​How can developers from different backgrounds make the transition?
   Transferable skills and knowledge gaps for backend, frontend, full-stack, testing, data and DevOps professionals.
6. ​What projects can survive resume screening and interview deep dives?
   How interviewers evaluate business context, technical choices, results, system design and deployment.

## ​👥 Who Should Attend?

• ​Backend, frontend and full-stack developers considering a move into AI application development
• ​Testers, data professionals and DevOps engineers looking to enter AI projects
• ​Developers who have learned RAG or Agents but are unsure how close they are to a real role
• ​Anyone who has built an AI demo and wants to turn it into a stronger portfolio project
• ​Computer science students planning their AI career path
• ​IT professionals who want to enter the AI industry without starting from algorithm research
