I think it might also end up not really working to reintegrate someone into the community, particularly dangerous jobs are not usually that open to the public to observe, and if they are deliberately filled with "habitual criminals" then that might create a bad reputation for people who have performed those jobs.

I havent put an extreme amount of thought into it but it seems like it might work better to try and spread "community service" or whatever equivalent program this would be into as many appropriate workplaces as possible to not form a specific reputation of any one type of job as relegated to criminals, plus some jobs will be more immediately connected to the community and help build or rebuild a connection between someone that has done a crime and their community.

Better IMO to provide incentives and respect for those who choose to do risky work, unless there is an immediate emergency need to fill those positions.
