I've been working for over a year now in this remote job as a sysadmin for a local client. I personally find this job quite intimidating at first with all of the infrastructure and all of its many microservices running in high availability set up. I enjoyed learning everything about them and why it's been set up this way, which gives me ideas if I were to build my own app (not competing with my current employer, of course).

But now I don't feel comfortable managing this beast in its many environments.

From time to time, I would hear from my old colleagues at my old sucky company for help in their work and that they know I'm an expert in. I help and it makes me feel good.

Now I'm at a career dilemma. I don't want to lose my current job because I feel "uncomfortable" with managing and administrating the tech holding the whole infrastructure. And I don't wanna go back to my old job with the sucky pay and the feel of being unchallenged. And if I try to find another job, I might be as lucky as I do now, especially good difficult it is for me to find a remote job to begin with.

Objectively, I just need to clear off my debts (at this rate, in 4 years), and have a side income to support my family. But I don't think I can follow through on that plan. Should I look for a new job or do better with the current job that I have now?
