I work at AWS on EC2. It's really not bad. Very competent coworkers, technical leadership, plenty of principal engineers willing to help... Oncall's tough, and we definitely need more engineers but otherwise, you learn a lot
EDIT: Added last sentence.
When was this? Just to confirm, you're referring to a data plane team and not a control plane team?
I'm just saying, it's worth giving a shot. You might like it. If you don't, switch orgs/teams. You can switch just a couple months after joining if it doesn't work out for you. I switched from my last org quite quickly cause while I had good work life balance, the work was just so boring.
