Do you need machine learning to be an AI Engineer?

Two different jobs. One confusing title.. Why most AI Engineer roles never ask you to train a model, and what they test you on instead. A terminal checks a job description and returns: AI Engineer, no model training, ML degree not required.

Hi {{ name }},

“I am in confusion, some people say ML is required for AI engineering.”

I’ve received some version of that message more times than I can count this year. So here’s the short answer, side by side.

ML Engineer

AI Engineer

Main job

Trains and tunes models

Builds products on top of existing models

Daily tools

PyTorch, GPUs, training pipelines

Python, LLM APIs, RAG, agents, LangGraph

The hard part

Getting a model to learn

Making a system accurate, safe and affordable in production

Needs first

Strong maths and statistics

Solid Python and engineering habits

Many job posts still say “AI/ML” because they were copied from older templates. Read the responsibilities and ignore the title.

If the work is LLMs, RAG, agents and evaluation, it’s an AI Engineering role, and you won’t be quizzed on backpropagation.

// NOTE

A 30-second test for any job description

Count how many of these appear: LLM, RAG, agents, LangChain, LangGraph, vector database, prompt engineering, evaluation.

Three or more? That’s AI Engineering. Mostly PyTorch, model training and feature engineering? That’s ML, and a different path.

AI Engineering is where most of the new roles are being created right now. It’s open to anyone who can write good Python and think like an engineer, whether you’re in college or 15 years into your career.

If you want to see the full path, from your first line of Python to a deployed multi-agent system, I walk through it in this video.
