Senior🎓
Top SchoolChristopher Ellis is a network security engineer with nearly a decade of hands-on experience in offensive security, red teaming, and penetration testing, now focused on securing enterprise networks at Plaid. He built and led Workday’s Red Team, driving vulnerability research, credential audits, and pragmatic mitigation strategies that bridged technical findings with organizational risk reduction. Earlier roles at Kaiser Permanente honed his consulting instincts and tooling development for PCI and targeted assessments across complex environments. Comfortable both leading programs and executing technical engagements, he blends deep exploit knowledge with enterprise-scale security operations. Based in Livermore, CA, he pairs a Computer Science foundation from San José State with a track record of turning intrusive testing into measurable security improvements. An unexpected strength is his background teaching programming, which he leverages to mentor teams and communicate complex attack paths to nontechnical stakeholders.
