There is a term for what you need to do. Autodidacticism. You obviously have grown into the job you have and now you administer the works of others who are at the cutting edge of the assorted tasks your company needs. Many senior engineers 'rust' out and would no longer qualify as a new hire. How often do you find yourself out of your depth on a project? This happens nall the time. There are huge chances for online learning that have been expanded by this pandemic. What to study? That is the question. You do not want to make yourself into a new hire. You need to identify what aspects of your current degree of education you need - and your company needs, to grow you into your role. Obviously this sort of self teaching is what you need. The problem is to find just what you need and in a disciplined manner get about learning this. There are huge numbers of free online courses. The MIT academy is one. There are also a large number of fee based institutions that offer the courses for free as long as you do not want the diploma that you can market. You are in your mid 30's from your timeline. I do not know if you have the free time, as you may be married with kids etc by this time. Hopefully your significant other will be completely behind you. Modern computer tech, thousands of youtube/Vimeo/etc instructionals are there to assist you while you do this in a stealthy way as you keep your regular job properly done. You will need to avoid game playing, consumer TV, etc., except as a limited relief from your future studies. Tens of thousands of people have done this with success, and you can as well - with discipline. Avoid scams and schemes, multi-level marketing etc = traps. Some other good ideas may emerge from others. Good luck.
