In this episode, we are talking about adaptability in engineering orgs, building out impactful management systems, and navigating complex transitions as eng leaders with Cosmin Nicolaescu, CTO @ Brex. He shares how his experience moving from Romania to the United States taught him vital lessons in adaptability that he has applied throughout his eng leadership career. We also discuss how to define what success as a manager looks like, Cosmin’s approach to putting out fires (and deciding which ones to prioritize), why you should restructure your meetings to focus on output vs. review, and how to implement a succession plan.

"How are you actually changing the trajectory of something. If the person wasn't there, would things have come out differently? If the person jumped in on something, did that meaningfully change the trajectory of that particular project? The answer should be yes and I think that is a good proxy for, as a manager, are you actually leading teams, people, projects, initiatives, and moving the company forward or are you just operating the machinery?”
