I'm sure you've started figuring out the tricks to finding positions that are friendly to people with criminal backgrounds, but if you're checking for positions on places like LinkedIn, they have a flag for people posting jobs that shows they are open to candidates with criminal backgrounds. You'll see the postings show "People with a criminal record are encouraged to apply" which I think is placed on the job description if an employer selects the "Fair chance" flag.
So you could narrow your searches down using "Fair chance"
Others like Glassdoor just use "People with a criminal record are encouraged to apply"
Now, whether those employers really mean it, or if it's a legal requirement they check that box, I'm not sure.
