Senior Offensive Security Engineer (Web)


Zoom is looking for a Senior Offensive Security Engineer to join our Offensive Security team. While you will be involved in anything from high level threat analysis and finding vulnerabilities, to helping patch vulnerabilities, a large portion of your time will be self guided. You will act like an in-house security researcher attacking the Zoom ecosystem, as well as contributing to team projects with predefined targets. 

Ultimately, we’re looking to find the highest-impact issues, and to prioritize remediation as part of a collaborative effort to create the most secure product. 




  • You will perform security research into Zoom products, features, and technologies.

  • You will conduct assigned and self-guided security testing of Zoom's applications and dependencies.

  • You will develop (independently or with a team) custom tools to attack said products and features.

  • You will assist with high priority issues (i.e. investigating a specific vulnerability to better understand it, fix validation, helping teams understand the details of a vulnerability, and helping developers fix critical bugs). 

  • You will communicate discovered issues, how to exploit them, and how to fix them for both technical and nontechnical audiences.



  • 5+ years of experience performing security assessments, penetration tests, and code reviews on Java, JavaScript, and Golang based web applications.

  • Experience manually identifying and remediating OWASP 10 vulnerabilities (CSS, CSRF, SSRF, and SQLi) as well as business logic flaws.

  • Have a command of your most liked pentesting tools, and know how to use them to your advantage (Burp Suite, Charles Proxy, nmap, etc.).

  • Proficiency in one or more programming languages, and can both read and understand code written by others well enough to break it.



Nice to have:

  • Familiarity with fuzzing (Libfuzzer, AFL++, custom, etc.)

  • Familiarity with CodeQL

  • Experience testing cloud environments (AWS, Azure, etc.) and identifying key risks to these environments
