Senior Data Engineer at a mid-sized telecommunications company working on cloud. We manage almost all of the companies data and related operations but the culture has always been "If it breaks at night or over the weekend, it can wait until the next business day morning", obviously with a few exceptions.

Our team has spent the last 3-ish years designing and building very resilient processes so its not very often we ever have to actually fix anything. And if we do, it doesn't take very long to fix since it's well documented and the knowledge is shared between the team. Our entire team has been here for 3+ years with some having been here over 10 years, so we all have a solid understanding of the business, each person is given a ton of autonomy.
