i can't even begin to know what the fuck a 'volunteer' Enforcer is, especially for a profitable company. quite frankly it sounds like the typical 20 foot pile of horse shit that only the games industry could come up with. and i've seen some really mind-bendingly exploitative behavior after being based here in LA for a decade.
anything significantly less than the above salary + benefits, and you are being ripped. off. by. people. who. know. better.
i know this because i have several senior devops guys on my staff who fit that description and have been with us for over 3 years. this is also what I used to make as a senior engineer before i started up my company as an owner/executive.
people should be FAR AND AWAY your most expensive resource. with a few notable types of exceptions, if you pay your people less than your hosting provider or your rent or marketing, you're doing something very, very wrong, and it will catch up to you in some way or another. see: penny arcade job post.
