OK so SOC.
Low level:
I think you should probably look at E/N/X/DR tools out there, but also SIEM. I suggest you search for these tools(and others) in the areas you want to work in. Examples Crowstrike, Sentinel One, Carbon Black, Microsoft, Symantec etc - Splunk, Sumo Logic, QRadar, Exabeam, Securonix, Arcsight… tweak these as appropriate work out the ones that companies use where you want to work attack rank and learn you top options. Download Kali Linux and practice.
Mid level look at your managerial experience, leadership chops and see if you think you can help setup.
Better yet get some mates who work there(in one) to introduce you.
Further education - Security+, Google Certified Cybersecurity Professional will likely be quite valuable, and any security vendor certs. SSCP may also help but frankly hands on certs(those with a portion of practice) are best here, and more useful than ISC2 IMHO.
