Zoom Security Engineering is hiring a Cryptography Intern for Summer 2022 to join the End-To-End-Encryption (E2EE) team. Come have a tangible impact on the security of a product used by millions of people, and help us design and deploy new cryptographic features across all of Zoom's products!
In particular, we are developing and deploying new cryptographic protocols for privacy preserving and auditable data structures (such as transparency trees), e2ee communications and identity assertions.
Candidates should have a love for cryptography and security, an interest in bridging the gap between the academic literature and industry requirements/constraints, and an appreciation for simple and elegant solutions.
Job Responsibilities:

• Survey the academic literature for existing solutions to a problem, recommending the most suitable given Zoom's constraints
• Develop new solutions to the problems above that are tailored to Zoom's needs, analyze their security and submit academic papers to crypto/security conferences
• Write architecture and design documents describing the problem, solution and security tradeoffs. These will both be shared internally to guide the implementation, and externally for transparency and community feedback. See https://github.com/zoom/zoom-e2e-whitepaper/ for an example
• Occasionally review implementations for security vulnerabilities and compliance with the specifications above

Job requirements:

• Pursuing a PhD in Computer Science or related field, with a focus on Cryptography
• Experience with threat modelling, formalizing new cryptographic primitives/protocols, and formally proving/analyzing their security
• Ability to clearly and concisely communicate ideas about complex systems, both in written and spoken word

(Preferred) Some experience writing Go and/or C++, with awareness of secure coding practices
