Engineers who engineer need to deliver. if you're a ninja and can do your weekly work in 5 hours, go for it. you can also be an engineer who doesn't engineer, but rather "guides" and "leads". this requires no work at all but you'll need to spend time politicking around writing docs and doing the leadership thing.
In science, it's like that too but more extreme, if you're a genius you can deliver your annual contribution in a week. if you're a "leader" you can do negative amount of work, i.e. deploy garbage, have your angry colleagues fix it, and then take credit for the fix and team leadership in crucial times.
However, if you can't do either, can't deliver with ease nor "lead" with venom, prepare to work your ass off.
Regarding culture, it's really nice and it's nice for real. Lyft takes the woke thing very seriously and anyone slightly not woke is promptly beheaded.
A bro was talking shit. fired. A manager didn't listen to women. fired. Some dude had a tantrum and scared another employee. fired. They don't fuck around with that stuff. be nice.
