Senior Offensive AI Security Engineer

What You Can Expect

This role sits at the intersection of offensive security and applied AI, focused on surfacing critical risks across Zooms products, applications, services, and infrastructure before they become incidents. Day to day, you will combine deep target knowledge, threat analysis, and cutting edge models to form hypotheses about where complex systems are likely to fail, validate exploitability, and trace attack paths that standard testing would miss. This is not a vulnerability-scanning or prompt-engineering role: a strong hands-on research craft is the foundation, and success is measured by whether your findings change how Zoom understands its risk, not by finding volume. Zooms Offensive Security team conducts vulnerability research across products, applications, and infrastructure, concentrating on high-impact issues that escape standard secure development processes or wouldnt surface through routine testing. The team is actively evolving towards AI-native research, where models extend how much ground experienced security engineers can cover and how quickly, paired with real target knowledge, a sound research strategy, and rigorous verification.
Leverage AI to conduct vulnerability research across Zooms products, applications, services, and infrastructure, with a focus on high-impact issues, subtle vulnerabilities, confirmed exploitability, and attack paths that cross component and trust boundaries.
Use experience, threat analysis, architecture knowledge, source code, and observed system behavior to choose targets and guide investigations.
Apply frontier and open-weight models, agents, and other AI capabilities across the research lifecycle: reconnaissance, code analysis, hypothesis generation, exploit development, and verification.
Develop custom tooling, including analysis utilities, fuzzers, agents, test harnesses, proofs of concept, and full exploits, when it helps answer the research question.
Convert promising model output into defensible security evidence: reproduce findings, rule out false claims, establish preconditions, and distinguish a possible weakness from a demonstrated vulnerability with real impact.
Improve the reliability and reach of AI-driven research by tackling false positives, false negatives, context limits, nondeterminism, and reproducibility.
Work directly with Engineering and Product Security to communicate findings, support remediation, surface related risks, and verify fixes.
Share tools, techniques, and lessons learned so Security Assurance and the broader Security org can enhance their processes through the use of AI.
5+ years of hands-on vulnerability research, offensive security, application security, or penetration testing, with a demonstrated track record of choosing targets, forming and revising hypotheses, and establishing exploitability and impact in complex software or production systems.
~ Experience assessing the quality of AI-driven research processes, including identifying false positives, missed vulnerabilities, unstable results, and reproducibility gaps, as well as sound judgment on agent architecture trade-offs: when constrained, orchestrated pipelines deliver reproducible results and when open-ended tool-using agents are worth the nondeterminism.
~ Deep technical expertise in at least one security domain: web applications and APIs, Java applications, cloud or service infrastructure, client software, operating systems, or reverse engineering.
~ Strong programming and debugging skills: ability to read unfamiliar code, build research tooling, write proofs of concept, and trace behavior across system boundaries.
~ Salary Range or On Target Earnings:
$base salary, bonus and equity value.
