Testing is typically referred to as Quality Assurance, so that's what you need to look for. It's a fairly niche role you're looking for, so there's not a lot around. A bit of googling turned this up :
XR Quality Analyst
An exciting opportunity has come up for a VR Content Analyst to join the in-house QA team working on ground breaking VR and Mixed Reality enterprise projects.www.luminousgroup.co.uk
I have no connection to the company at all. The job description might give you an idea of what you'd need skills wise.
FWIW testing is an under-paid, under-appreciated, surprisingly skilled profession. It's not just playing around in VR or whatever all day, it's very process-oriented and suits very well organised people.
I'd say it's pretty straightforward these days, with the skill shortages. Loads of opportunities for junior developers and people without industry experience at the moment. You're not going to walk into the industry easily, but anyone who puts a bit of work into their profile will manage it.Getting a job in games is hard enough (even with industry experience), let alone a part time, WFH one. Not meaning to put you off, but I wish you good luck because you're gonna need it.
I wouldn't limit yourself to VR in that case.I thought it would be great if I could use my computer to help me generate an income, if possible, as I have a VR set up and the hardware to match then maybe they might need people like myself to help them test during the day while my son (5) is at school?
