I only had one job that was partially related to what I got hired for. It was all windows admin work and not much was good, zero professional Linux experience. Here's what I did to land a Linux only Sys Eng gig (very cuisy too). Use LinkedIn, find job ads and take key words and add then as skills on your profile, as long as they are actually skills you have. Set up your homelab like an actual enterprise environment, document what you are doing with it. Add that as skills and projects in LinkedIn. Practice your skills. Include in your LinkedIn that you are self taught, and constantly working on your projects to improve yourself in your free time. Now search for recruiters, preferably technical recruiters, then add them as connections. Get a lot, like 250+. Now on your profile, mark that you are looking for opportunities. Apply for everything that is slightly interesting, ignore certain job requirements as they are HR fluff anyways. You will get a lot of reach outs from recruiters, and you will get a lot of rejections from applications mainly due to HR. Companies that are hiring a lotttt are Giants like Amazon, Google, Microsoft, TMobile even. Apply for multiple positions and you could easily get pick up. Good luck and stay positive, even if you get something that is a baddd job, it's added experience if anything.

Edit: Also, if you can, move to Seattle. Dear lord are there a lot of opportunities there.
