Cal Poly SLO and SJSU have excellent CS programs and great job placement. They have a lower price tag than the California UC’s around $36K-40K/year but you will not be eligible for FA since you are an OOS applicant.
SLO’s acceptance rate for CS is around 10-13% so definitely not a guaranteed Match. SJSU is bit easier of an admit but extremely popular due to its location: Silicon Valley.
If finances are not an issue, consider applying to both.
