> Some companies hire dedicated tech people whose only job is to be oncall, handle alerts, and improve the oncall infrastructure. This role is called ‘DevOps Engineer’ at some companies, SRE (Site Reliability Engineer) at others, and may also be called ‘Operations Engineer.’

Any company that I've seen put SRE/"DevOps"/... as the sole primary on-call rotation basically just created a glorified operations team.

Unless you have shared pain for botched releases, you will never get rid of these problems.
