Honestly, depends. Some teams at FAAMNG are really stressful and if you work on a Tier 1 service even with loads of SRE support you have to be working a fair bit. That being said, the pay is for design decisions at the higher IC level (senior or staff) and most people at that level are very smart. I’m not saying this salary is for 10x engineers or anything.
I would say 50% the work is harder and consuming and then 50% they can just afford to pay you more and lock up talent because of the wild margins on their products.
