The Role
As an Applied Cryptographer, you'll design cryptographic systems for secure identity and data protection, evaluating existing protocols and developing new techniques.
Summary Generated by Built In
Mindset

You think about how cryptographic primitives can be used to secure identity, access, communication, and storage of data. Have opinions on how trust, authorization, and credential systems should evolve with newer advances in computing and algorithms. Understand the principles that go into designing robust and adaptive cryptographic systems. Are able to identify potential flaws in a given cryptographic scheme, protocol, or implementation.


What you’ll do

You will work on the cryptographic foundations that let people, agents, and systems establish identity, delegate authority, and protect sensitive data. The job is to turn messy security requirements into mechanisms that are precise, durable, and usable in practice. You might design identity and access systems, build credentialing and key management infrastructure, develop secure and privacy-preserving protocols, or evaluate existing systems against realistic attack models. The aim is not just elegant cryptography, but systems that remain trustworthy under real-world use.

Preferred Background
  • Designed and implemented identity and access management systems that use cryptographic techniques to ensure the integrity and confidentiality of sensitive data.

  • Developed cryptographic protocols to enable secure communication between distributed systems and trusted services.

  • Designed and implemented privacy-enhancing technologies to enable secure transactions and communication while preserving users' privacy.

  • Built secure key management systems, credentialing infrastructure, and other tools to enable users to manage cryptographic material securely.

  • Analyzed and evaluated the security of existing distributed systems and identifying potential vulnerabilities or weaknesses that need to be addressed.

  • Researched and developed new cryptographic techniques to address emerging security challenges in modern software systems.

What We Do

Mem Protocol builds tools to help agents (humans, bots, organizations) manage relationships. Today, you have many representations of yourself online, with each of those identities tied to specific apps. This limits how you can express yourself and the actions you can take. We’re building tools so you can represent yourself however you want, wherever you go.
