"Not the profile they are looking for" in this case sounds like "overqualified", possibly with the expectation that you'll want to much money or are going to try to get a higher-level job soon. To much experience on the software side.

"DevOps for a Fortune 500" doesn't sound like you spent much time fixing hardware, CS degree isn't all that relevant either. Note that "Basic knowledge of Linux and networking" is quoted as a "preferred qualification", vs "Intermediate knowledge of computer hardware systems" and "Able to lift/move up to 20kg equipment on a daily basis" being basic requirements.
