Where's a good place to look for entry-level GRC jobs?

If you are located in the US and aren't currently a complete fuck-up, the Federal Government can be a way into the GRC side of cybersecurity. Between civilian and DoD sites, they have analysts and auditors all over the place and always seemed in need of folks willing to pour over checklists and OQE artifacts. This first place to look for positions in that vein would be on usajobs.gov. Though unfortunately, the FedGov made the decision to classify both GRC and sysadmin positions under the 2210 category; so, you'll probably have to dig through a lot of sysadmin listings.

Another path into similar positions is to look for FedGov/DoD facilities in your area. Once you find one, take a drive around the area and look for the names of businesses in the area and start researching those businesses and their open positions. There will almost certainly be the big ones, like Booze-Allen Hamilton, BAE, Boeing (yes, that Boeing. They do a lot outside of crashing aircraft), etc. But there will be a plethora of smaller companies with seemingly random names and little public facing who supply the local site with hordes of contractors. And, while these are contractor positions, they are a lot more stable than contract positions in the private sector. I spent 6 years as such a contractor and only stopped being one when I took a job elsewhere.

I will say that "entry level" is going to be harder. No one wants to hire an train someone without experience, which puts you in a catch-22. For all the suck involved, you may want to consider putting in some time working a help desk. At minimum, it keeps you in proximity to the field, teaches you something about systems and provides related, if not direct, cybersecurity experience.

Best of luck.
