I have had two tech jobs like that, even before COVID, starting in 2016. The first time, it was a company that outgrew their workspace. They put us in ‘rent-an-office’ spaces for a bit, and then my boss started working from home a few days a week. Then he allowed me to. We moved to a new office, but it was always empty in my section. That was fine, too, but the commute was terrible, so I started doing 2 days a week, then once a week, then a few times a month. I rarely saw my other coworkers in person, and nobody said anything aloud.
The next job started because of COVID, and when they started doing RTO, they also wanted to do “hot desking” (no assigned seating) and open office plans, and I was not having that. I was not going to work in a “cafeteria” like setting. So I got contracted work and have worked from home 100% for several years now. Nobody has office space, and we work all over the world to collaborate. I get paid very well.
I hope i never had to go back to an office. I reach retirement age in about 15 years, and I am hoping to make it.
