Remote federal employee? I suggest you double check with your manager about working remote from overseas, especially if you are talking about the American government.
I’ve flown in and out of Singapore maybe 6-7 times (I’m a Pass holder) after I got my DTV with no issues on either side. Just make sure you submit your arrival card online so you can use the e-gates with no issues.

You will get a receipt for your arrival card via email that you can show if anyone asks for whatever reason.
