Pretty sure you're being facetious, but yes, each team of SDEs is responsible for their own operations. Reliability Engineer positions do exist, but there doesn't seem to be a company-wide standard job title.

There is a group (Operational Excellence) that focuses on things you'd expect SREs to focus on, but I think they focus more on building the tools than actual operational support.
