Senior🎓
Top SchoolJon Barber is a founding engineer and security-focused technologist with 12 years of experience building large-scale security programs and tooling for major tech companies and startups. He led security automation and shift-left initiatives at Cruise, designed large-scale asset discovery infrastructure as a researcher, and ran bug-bounty programs and private bounty initiatives at Facebook. Jon blends deep offensive security experience with pragmatic engineering—shipping company-wide vulnerability scanning, DAST/SAST pipelines, and pre-commit/PR-time checks that scale across hundreds of services. Now based in Seattle, he’s applying that background to early-stage product and platform design at RunSybil, pairing a creative film and animation background with rigorous computing security training from RIT. Colleagues describe him as someone who genuinely enjoys “building and breaking things,” turning attacker insights into resilient, developer-friendly defenses.
