An Insider's view of System1

What does your typical day look like?

I definitely never have the same day twice! I truly look forward to going to work and a big part of that is the variety of projects I get to work on and people I get to work with. While I love digging in on the latest anomaly in the data, I’m also a people person, and this role is really the perfect balance of screen time and face-to-face time.

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.
