Dir of Eng @ Mosaic | Over 90% of Their Code Is AI-Generated

What does engineering leadership look like when more than 90% of your team's code is written by AI?

Adrian Chang, Director of Engineering at Mosaic, joins Josh to talk through what that actually means day-to-day: how the old LeetCode interview stopped telling you anything useful, why AI fluency is now a requirement for every hire, and what happens to code review when the machine is writing (and approving) most of the pull requests.

They also get into the part that doesn't change. The tooling has flipped completely, but the job of growing the business, shipping quality, and keeping a team steady through the noise is the same one it always was.

Adrian shares the advice he wishes he'd had on the way up: when you move into leadership, treat yourself like a junior engineer again. Year zero. Your years of experience get you maybe 10 to 20% of the way there.

A good one for anyone leading a team through the AI shift, or building the mental model for the seat they're heading toward.
