I feel like if you care enough about your other job that you don't want to lose it, the best route is to ask your employer about moonlighting.

You don't tell them and you get caught: You're ****ed.

You ask, they say no, and you get caught: You're ****ed.

You ask them and they say "you can moonlight when you aren't on the clock and as long as it doesn't impact your work here," and you get caught on the clock: You might be ****ed, but can at least play it off as a one time thing or hell, tell them you're quitting the other job because the other company ****ed up by calling you or whatever. And at worse... you're ****ed.

But, what if the question raises suspicion? ....well, if you care about your current job not to **** it up, wouldn't you already be trying to not raise suspicion if you hadn't told them? In other words, not sure I'd be MORE paranoid after asking than not asking at all. The outcome is the same: do what you need to do to keep your primary job.
