This is an old article from 2017, but hopefully may be still be relevant in that SLO is ranked #14 and UDub is ranked #18, which is essentially the same, in terms of jobs in SIlicon Valley “back in the day.”
My guess is that job prospects will be similar.
My D21 attends SLO. Whenever she calls me during the day, she’ll be sitting on some green area/space on campus and it’s so quiet around her you can hear a pin drop. I don’t know much about UDub, we visited for D18’s admissions cycle, but it’s roughly twice the size when you add graduate students and it’s very, very busy on campus.
SLO is laid back, less stressful IMO, but D21 has gotten an excellent research opportunity and also a great local job in her career field. And while she was interviewing for the job, the HR people said that they love SLO students, because they already know what they’re doing in terms of the job requirements.
ETA: She also can see any professor, let’s say in the Chem department, if she has a question, not just her professor. They all post office hours and she can see any of them.
