Quite the opposite, interestingly, I’m usually in “Platform”-ish roles which touch or influence all aspects of the business, inc. building and operating services which do a couple orders of magnitude more than OP’s referenced scale (in the $job[current] case, O(100B - 1T) requests per day) and while I agree with the “Upside” (career progression, intellectual interest, caliber of people you work with), I haven’t experienced the burnout and in 2022 am actually the most energized I’ve been in a few years. I expect you can hit burnout building services and systems for any scale and that’s more reflective on the local environment — the job and the day to day, people you work with, formalized progression and career development conversations, the attitude to taking time off and decompressing, attitudes to oncall, compensation, other facets. That said, mental health and well-being is real and IMO needs to be taken very seriously, if you’re feeling burnout, figuring out why and fixing that is critical. There have been too many tragedies both during COVID and before :-(
