Money is good. There are mentors available for SDE1s, and managers have incentive to get you promoted.

There are also tech talks every week and a strong engineering culture.

If you want to learn, you have infinite opportunities to do so.

Oncall - getting woken up at 3 AM to work is the worst feeling ever. Depending on the team you join, it might happen way too often.

It can also be hard to find senior engineers to learn from or to have as a mentor. The company is very young, and the turnover is high.

I've been there 3 years, and my tenure is longer than 66% of the employees in Seattle.

Do more to attract experienced talent and get them to mentor, give talks, maybe even teach classes. There are not enough experienced engineers to learn from, and the ones who are there don't have time to help others learn and grow.
