I've also noticed that having dealt with Open Source software, knowing the software and exposure to it is important.
I have a CCNA which expired lol but I have dealt with a lot of Linux. I was going to get a RHCSA/RHCE (literally missed my RHCSA by 14 points and never re took it!) but a lot of the stuff I touch is Ubuntu/SuSE at the moment and I personally use a lot of ArchLinux myself.
With that said it would be nice to have certain certifications, outside of the Saltstack one I have (configuration management) to get more looks.
The biggest thing that is hurting me now is that I haven't been in development roles. I interviewed with IBM and they told me they want someone with more development experience for the role, but the guy I talked to simply talked to me about systems and OpenStack which I worked with for years.

It kind of pissed me off because it was a time waster knowing what they want. She is going to refer me to an Operations role though but I've heard bad things about IBM.
Another thing is that I don't have a degree and that may or may not be a deal breaker for some positions. I have some college at a really good university but stress/depression got the better of me at the time.
Honestly though given my experience I have had Facebook, Google, and LinkedIn contact me for high roles. When I left the web hosting company I was at I was making 70K in Texas. I was making six figures in my last role. The roles I look at I say that figure and they are cool with it.
I know with some roles with certain companies, and especially dealing with Government hardware they require a Degree. I do see some of my white counterparts with fukking history / polysci / and other Liberal Arts degrees though and they get these lucrative roles by working through the ranks.

Always as a black person you have to do more.
With that said though I am in my early 30s and been fukking with Linux since I was a teenager so I'm comfortable with my Operating System knowledge and I'm fortunate enough to get the exposure I have had thus far. Once I get established in my next role though I AM going back to school for Data Science.
I'm only two weeks into my job search though and things look promising enough that Indeed is flying me out next week for a Site Reliability Engineer role. Also some other companies are talking to me in the first stage of things. I just hate the process.
