## The short version

Judged by social media, design engineering looks like animated eye candy, which Jakub says is well wide of the mark. Ten people will give you ten definitions of the role, so he wrote down what the job actually involves day to day. Most of it is accessibility, responsiveness, performance and the edge cases that only surface once people use the thing. None of that is interesting enough to post, and all of it decides whether the product feels good. The piece makes the case with live demos of hit areas, reduced motion, locale formatting and a 500ms action next to a five second one.
