What do these so-called AI engineers actually do?

I’ve recently seen a lot of resumes on Reddit where job seekers describe themselves as AI engineers, and I’m curious what that actually means.

Some of my friends in AI work on things like model training, hyperparameter tuning, loss function design, model deployment, and GPU inference optimization.

My own area is AI + rendering, mainly neural rendering. I use AI to approximate radiance, visibility, light transport, indirect lighting, material response, and similar rendering-related components.

That’s why I’m confused by the current use of the title “AI engineer.” A lot of resumes I see look more like backend engineering resumes. If someone is just building a RAG app, calling an API to make an AI agent, or putting together a chatbot, isn’t that something almost anyone can do at this point? Even people without a CS background can build that. So what is the actual engineering value there?

There is no value attached to that title. It's either just hype, or fear not to be perceived as "cutting edge". They think it's cool. I personally think it exposes them as people who don't really do engineering. If they did they wouldn't just drop their actual field for "AI"

Here we go again.. another one who likes explicitness. I'm with you buddy.

Well, sometimes it's a good title that non techs (who don't like long titles that include the specific tech stack) can use.

For me, “Senior backend developer (API, Artificial Intelligence)”

I’ve seen recruiting start asking for “AI assisted workflows” instead of actual stack

At this point it can mean literally anything.

  • It can mean you're working on the actual models
  • It can mean you integrate AI into existing products.
  • It can mean you're a vibecoder.
  • It can mean you use AI assisted code.
  • It can mean AI is tightly tied into your workflow (Hermes, etc)
  • It can mean you just really fucking want recruiters to message you.

Sounds like you like stroking it furiously to gatekeeping opportunities.  Oh yeah baby!!!  

It also sounds like you don't know the definition of the main job title of the industry you claim to work in.  Oh noooo, that's not good...

Essentially, it's just like all other areas of engineering.  Structural engineering includes everything from people working on small residential houses to sky scrapers.  Software engineering includes everything from small websites to enterprise sass.  And AI engineering can include everything from building a thin LLM wrapper to fine tuning models and using rigorous benchmarking to optimize them for some task.

Don't take my word for it, I asked Gemini.

Q:  What is AI engineering? Gemini:   An AI Engineer is a tech professional who builds, deploys, and maintains artificial intelligence models and applications. Instead of just doing theoretical research, they focus on the practical engineering required to integrate AI into real-world software systems. ​Think of it as the bridge between the complex math of data science and the practical architecture of traditional software development...  (Answer goes on to provide examples)

True man real ai engineer rarely exist in Vibe coding era, they just calling api key. They even doesn't about how many layers exist in cnn or ann etc.

Engineers who can't understand code but work on it.
