An Insider's view of System1

What are some social events your company does?

One thing that System1 really prides themselves on is company culture. We want everyone to feel like family at the company and nothing brings people together better than our social events.
I enjoy attending events like LunchNLearns, team happy hours and anniversary or holiday parties because I learn more about my teammates outside of the office.

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.
