The first thing you should do to look like a professional user is to spell them correctly:
LabVIEW is an acronym (hence the capital letters)
TestStand is one word with a capital S.
I automatically disqualify resumes that don't spell them correctly. My assumption is that the person is sloppy in the details and will write bad code. Especially on a resume that should be reviewed multiple times.
As buton mentioned you can go to indeed.com and type in TestStand and see what is out there. Same goes for LabVIEW.
Most companies that would hire experts in these areas are testing hardware. However, LabVIEW has recently taken off into other areas, specifically control systems. In my opinion there are different types of LabVIEW users out there, especially given that there is LabVIEW Embedded and LabVIEW RealTime. The other thing I notice with LabVIEW jobs in particular is that they want other expertise, for instance RF knowledge or digital knowledge or someone who is great with FPGAs. In other words, they expect you to be both a Hardware and Software engineer.
Finally, it doesn't hurt to become certified through National Instruments. For more on that check out this website: http://www.ni.com/training/certification/
Good luck in your search and hope this helps,
