Senior AI Security Research Engineer

Zoom; Augusta (ME); Hybrid; USD 124,000 - 271,000; Full time

Job summary

Zoom is seeking a Senior Offensive Security Researcher to surface critical risks across Zoom's products, applications, services, and infrastructure. You will combine hands-on vulnerability research with AI-native methods to form hypotheses, validate exploitability, and trace attack paths that standard testing would miss.

In this role, you will collaborate with Security Assurance teams, design custom tooling, and produce defensible security evidence.

Qualifications

• 5+ years of hands-on vulnerability research or offensive security experience.
• Experience with frontier and open-weight models in offensive workflows.
• Ability to assess AI-driven research processes and reproducibility.
• Deep technical expertise in web apps, APIs, cloud or service infrastructure, client software, OS, or reverse engineering.
• Strong programming and debugging skills; ability to read unfamiliar code.

Responsibilities

• Leverage AI to conduct vulnerability research across Zoom's 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.
• Design and tune research harnesses that give models the right context, tools, execution environments, and feedback to investigate real targets.
• 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.
