30+ security engineer jobs in San Francisco from 18 employers. Get referred by a verified employee instead of applying cold.
RefOpen currently lists 32 live security engineer roles in San Francisco, posted by 18 different employers, 25 of them in the last seven days. The companies posting most often right now are OpenAI, Anthropic and Harvey. Every one of these is a real opening pulled from the employer's own careers page or an aggregator, not a reposted listing.
Job titles in this market cluster around Security Engineer, Product Security Engineer, Staff Product Security Engineer and Senior Security Engineer, Detection & Response. Titles vary far more than the work does, so it is worth searching the family rather than one exact phrase: a "Security Engineer" at one company and a "Product Security Engineer" at another are frequently the same job at the same level.
San Francisco is a competitive market for this function, and with 18 employers hiring at once the same candidates are applying to many of them. A cold application lands in an applicant tracking system alongside hundreds of others and is filtered before a human sees it. A referral is submitted from inside the company, which puts the application in front of a recruiter as a named recommendation rather than another row in a queue.
Create a RefOpen profile, find the security engineer role you want in San Francisco, and request a referral from a verified employee at that company. You do not need an existing connection there. If nobody takes up your request, the cost is refunded in full, so the downside of asking is nothing.

Yes. That is what RefOpen is for. Verified employees at the company opt in to refer candidates they do not already know, so you are not dependent on an existing network.
No, and any site that promises one is misleading you. A referral gets your application read by a person inside the company instead of filtered by software. If no employee takes your request, RefOpen refunds it in full.
Browsing jobs and creating a profile is free. Requesting a referral costs a small amount, priced for the local market, and is refunded if the request is not taken up.
