Hold on, so you raised to your manager that you're getting burnt out my late night meetings & his solution was to move you to a role where late night meetings are inevitable?

To be honest, he doesn't sound very good — I'd either try to change manager or change company.

To your wider point — there are still companies that have a more traditional dev vs ops/sysadmin separation. Especially bigger, more traditional businesses (non tech start-ups) that still do their own software dev in-house.

Otherwise, you could get a role where the quality of tooling & support while on call is better. There's a difference being 1st line support in a place where things are always on fire and being 3rd line support in a place where the only time you're getting a call is once in a blue moon and there's a postmortem afterwards to work out how it could've been prevented.
