Offensive Security Engineer (Client/Backend)

REMOTE / PRODUCT SECURITY / FULL-TIME

 

Zoom is looking for a Senior or Staff Offensive Security Engineer to join our Offensive Security team. While you will be involved in anything from high-level threat analysis and discovering vulnerabilities to providing guidance on vulnerability remediation, a large portion of your time will be self guided. You will act as 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. 

 

Responsibilities:

  • You will perform security research into Zoom products and features, including contributing to custom tool development (such as fuzzers, proof of concepts, or full exploits) to attack said products and features.

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

  • 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 security issues). 

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

 

Requirements:

  • 5+ years of experience performing security assessments, penetration tests, and code reviews on C/C++ (Objective-C, Swift, Java, and Python a plus).

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

  • Familiarity with intercepting and modifying traffic using your tool of choice  (mitmproxy, proxyman, Charles Proxy, Burp Suite, etc) 

  • Security-specific knowledge for one or more OS (Windows, macOS, Linux).

  • Familiarity with building and instrumenting applications (such as using frida-dynamic instrumentation).

  • Ability to find vulnerabilities and create proof of concepts without being able to fully instrument a target nor attack it very aggressively.

Nice to haves:

  • Knowledge of Erlang, Lua, xmpp, or SIP 

  • Knowledge of network packet handling/traffic routing

  • Proficiency with IDA Pro, Ghidra, or Binary Ninja

  • Prior development experience

  • Familiar with advanced traffic interception setups in which the the client and the server communicate simultaneously over a variety of protocols that transport plaintext (e.g. HTTP) as well as binary encoded (e.g. protobuf) messages over secure channels

  • Familiarity with CodeQL

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

  • Knowledge of reverse engineering Linux binaries without source code

  • Experience debugging and automating detection of error states and causes

  • Ability to quickly pick up programming languages for code review

Fraudulent Employment Offers

Zoom is aware of scams that involve fake Zoom job listings posted on third-party sites. Responding applicants are contacted primarily over email, InMail and/or chat applications by people impersonating Zoom employees. Eventually a fake offer letter is sent in exchange for personal identification information as part of a fake new-hire screening process.

Please be advised that these offers, communications and impersonations are illegitimate and fraudulent. All communication with Zoom employees come from a “@zoom.us” email address. Zoom job applicants complete an interview process including in-person (on Zoom) meetings and phone calls. Our process also requires you to create an account with our applicant tracking system, Workday.

Zoom will never ask for your personally identifying information during the interview process or ask you to pay money or purchase equipment. If you have received a message from Zoom that appears suspicious, please contact careers@zoom.us.
