Is This Job For You?

A five-minute orientation before the real chapters: what an AI Evaluation Engineer actually does, whether it fits you, and how to get everything out of this course for free.

The job, in one sentence

You are the person who can answer, with data, the question every team building with AI is desperate to answer: "is this thing actually working, and did our last change make it better or worse?" Models are easy to plug in now; knowing whether they're good enough to ship is the hard, unsolved part — and that's your job.

Do you need a PhD or years of ML? No.

What you need is comfort reading and writing basic Python, curiosity about numbers (you'll meet a little statistics, explained from scratch), and care about detail — the instinct to ask "how do we know?" instead of "it looks fine." If that sounds like you, you can do this job.

Why it's a great first role in AI

Evaluation is one of the most in-demand and least-staffed roles in AI right now: every company shipping LLM features needs it, and few people specialize in it. It's also a way into AI that doesn't require training models — you work on top of them. And because the discipline is only a few years old, there are no veterans to compete with.

How to use this book

Each chapter is a short worked read → a hands-on Try-It lab → a worked solution → a quick quiz. Do the labs. Every one runs free — no API key, no credit card, no spend — so there's no excuse to just read. By Chapter 12 you'll have built a small but real evaluation system you can keep on your laptop and show in interviews. That portfolio piece is worth more than any certificate.
