Q: How long does it take to become an AI Engineer?

Assuming you're coming from an engineering background, with structure and consistency: around 3 to 6 months alongside a full-time job to reach a job-ready level. Without structure: often years, and many people never get there.

Here's what job-ready means concretely: you understand the stack from first principles (LLM APIs, RAG, embeddings, vector databases, agents), you've deployed real systems to production, and you have a portfolio a recruiter can click.

Note: many capable engineers take much longer to transition to AI Engineering because they get stuck, and it's mostly due to one of two things: structure and accountability. There's a lot of ground to cover and without a solid structure, you can waste months bouncing between Youtube tutorials learning things in random order. On the other hand, even with a great structure doing this alone with no accountability can feel challenging and most people stop after a few weeks.
