Clever Eng Blog — Always a Student

Always a Student is one of Clever's culture tenets: we love to learn, and this blog is where we share what we learn on topics that matter to engineering, from small but critical technical details to how we organize our engineering teams. This blog is cross-published on Medium.

Defining Clever’s Engineering Culture

By Caroline Modic on

At Clever, we chose early on to deliberately define the key principles we wanted our culture to reflect. These tenets are a part of day-to-day vocabulary, and we think they make us a stronger team.
