I read this article with a bit of hunger and nostalgia to return to my former life as a startup engineer... but I think upon further thought I'm leaning against it again. As a bit of history, I worked as an engineer at startups for most of my early career. Mostly frontend work, all SaaS businesses. I enjoyed it. I wore many hats, and got to think about the customer a lot. I didn't like always worrying about my paycheck and job security. 2 years ago I transitioned to a Platform Support Engineer at Heroku. Now I manage folks on that team. The thing I loved most about startup life was getting to be engaged in every facet of the business - my voice carried weight in technical aspects, financial aspects, support, culture, etc. I have a natural aptitude for things beyond just programming, and think often about the larger business and customer impact. It was great being able to speak up and leverage those parts of my brain. However, part of me thinks that perhaps the joy I found in being involved everywhere was that it made me feel smart. I felt like I could be an expert in every domain. But that's not really realistic, is it? Today I work in a very small domain with a limited breadth of responsibility... but I am _the_ expert on developer support. There is no one else in the organization (outside of my team, of course) that can challenge my thoughts on support, because I am the expert. Similarly, I would not dare challenge the expertise of our finance team. I know quite a bit about finance, but they blow me out of the water. They're specialized, and undeniably make better decisions than me. Is it really that much better to feel smart and make average/bad decisions based on intuition? I'm not sure. I think as far as output goes, specializing is better.
