Pros
Every company says their employees come first, this one honestly means it. All benefits are fully paid by the employer. They're very generous benefits, and the benefits keep getting more expansive each year. It is the most diverse workforce I've experienced in my career, and it is wonderful. The management is genuinely honest and transparent, you can literally ask them anything, and they give you that opportunity frequently. As a certified public benefit corporation that focuses heavily on providing free, open source data science tools you get to work in an environment that doesn't put the dollar first and foremost. There's no shareholders to push leadership around. Remote-first means everyone works remote, it is baked into the company culture. There is amazing work life balance, you're encouraged to take time off. Frequently. You'll get to work with smart, friendly, honest, nice human beings. Nobody yells, points fingers, or blames. We make mistakes and then have honest discussions about the process instead of the people. At the end of the day it's still a job, and you still do work, and the company still wants to make money so it can keep striving towards its many goals. But it's a great place to do all of that. There are no employee referral bonuses, but I still refer everyone I can.
Cons
It is still a small company, with small-company immature processes. That small company now has hundreds of employees after hiring significantly over the past couple of years. So there's a lot of growing pains around trying to determine and implement process and efficiencies and figure out how to make all of the parts of the machine work well together. Remote-first is definitely not for everyone. You have to posses fairly good self-motivation, and be willing to connect virtually, and know when to take breaks, go for a walk, work from a co-working place or coffee shop so you don't forget there's a society outside of your personal work-from-home environment, and time off to stay fresh.
