I had a word with my SPE today. He says you need to apply through the Patent Office website. Then your name will be on a list, and supervisors may want to make offers to you. It depends on just what your skills are, which sublists you'll appear on (mechanical electrical, biotech, etc.) if I understood correctly. Then if a SPE in the appropriate art has a vacancy, he may get in touch with you, depending. Alos, the USPTO is hiring for now; it may or may not be, as of January 20th. The new administration may impose a hiring freeze for a while. We'll see.

Good luck finding a decent job somewhere.
