There are a lot of industrial physicist jobs out there which are fairly unknown. After my fusion startup went under, I had a lot of trouble finding a position. I had engineering experience, but no engineering degree, and I didn't have the academic credentials to get a decent position in academia.
After months of searching, I ended up working for a medical physics company by complete chance. I was getting a haircut for a job interview at a defense contractor, and I mentioned to my hairstylist that it was really tough to find a job as a physicist. She said, "Oh, I know a guy who's looking for physicists". It turned out she also cut the hair of another physicist who had started a small company. She gave me his number, and I got hired.
It may be helpful to look at industries which hire physics undergrad degrees. These include anything which uses radiation or high vacuum. Math-heavy industries do as well.
It's a bit out of date, but here are some articles from the old Industrial Physicist magazine (check the careers and hidden physicist sections) which may provide some ideas: https://web.archive.org/web/20071017063629/http://aip.org/ti...
