## Description

* Pragmatic: you like to move forward and make decisions based in reality (not theory). We don't debate if Cassandra has the most theoretical scalability - we use Postgres until it breaks
 * Hard working: 'You can work long, hard, or smart, but [here] you can't choose two out of three" - Jeff Bezos. We wrote this job post during the weekend
 * Curious: you love to learn, are highly curious about new frameworks and solutions to engineering problems
 * Fast-moving: you deploy daily, iterate quickly, and never wait for permission
