System1 has the highest caliber of talent I’ve experienced in a company. I work with so many smart people that push me to think differently. I am constantly evolving because I am immersed in really thoughtful and intelligent conversations.

Since joining System1, I've grown in both my technical abilities as well as my interpersonal abilities. I've been given the opportunity to steer a complex migration that spans across teams and then provided with the freedom to pursue solutions that have a real impact on the daily operations of our engineering team.
