Ten years ago, the best engineers were the ones who could build anything. That's not true anymore.
AI already writes production code, reviews pull requests, and ships features faster than most teams. And it's only getting better. So what happens to the engineer who spent a decade getting really good at code?
Here's what we've seen firsthand. The engineers who keep getting promoted, who get pulled into the important rooms, who become the people companies can't afford to lose... they're not the best coders. They're the ones who understand why something should be built in the first place. They think about users, trade-offs, business outcomes. They think in products.
Nobody teaches you this. Not your CS degree, not your bootcamp, not the twelve tutorials you binged last weekend. You're expected to just pick it up on the job. Most people never do.
We wrote this book because we were those engineers. We spent years figuring out product thinking the hard way. Bad launches. Misread priorities. Watching less technical people get the roles we wanted. Everything in here comes from real decisions at real companies. The frameworks, the mental models, the product instincts that actually matter when it's your call to make.
If you're an engineer who's great at building but keeps wondering why that's not enough anymore, this book is the answer we wish someone had handed us five years ago.
