IMO, sysadmin and devops could be a perfect part-time or retainer type role for many smaller companies. They might need someone to help them occasionally, but not full-time. If I were you, I'd reach out to a lot of smaller (say <10 engineer) startups and present a consulting package of sorts. This could be as simple as a paragraph and bullets on things you can help them with, the hours, and your rate. You can probably source companies by looking at LinkedIn or searching for whatever tech stacks you're best on and filtering in your results from there.

Shamelessly, I've also started https://parttimetech.io/ to try to cover cases like yours where people don't want to work full time but still have very valuable skills to share. We don't have devops roles up yet, but hopefully will in the future.
