I would heavily advise that you don't do a devops/sysadmin job. I think you'll find that your idea (probably as a software developer) of what that work entails is grossly incorrect. It has /higher/ expectations than most developer positions, because your changes has more direct impact on production with less guard rails. Career advancement possibilities and salary may not be there, but the expectations are very high, and it is usually highly involved in the product if the product is something served over a network (SaaS/Cloud).
