As a cyber researcher at Irregular, you will be at the forefront of research on AI security. You will engage with questions such as how to protect the weights of an advanced model against cyber threats, and how to evaluate cyber capabilities such as AI’s ability to exploit vulnerabilities, carry out network attacks, and develop malware. This role sits at a unique intersection of cybersecurity expertise and AI capabilities, where your background in vulnerability and security research will help shape the future of AI security.

Representative projects:

  • Expanding the quantity, quality, and variety of our cyber capabilities evaluation challenges (e.g. constructing original CTF-style vulnerability & exploitation challenges, network attack simulation challenges, and more, including original types of challenges).

  • Leading research into methods to mitigate cybersecurity risks related to the misuse of AI, the theft of model weights, or risks associated with integrating models with dangerous capabilities in AI agents.

  • Publishing your research and/or delivering research to our customers.

  • Advising and supporting the development of the products we’re building.

Representative research questions about AI frontier models:

  • Can an AI find and exploit 0-days?

  • What’s the best way to measure a CTF challenge's difficulty level vs. an AI player's skill level?

  • Can an AI elevate an average computer science student’s cyber capabilities to that of a nation-state?

You may be a good fit if you:

  • Have a strong background in vulnerability/security research & development such as having found vulnerabilities/CVEs, analyzed malware, researched detection methods for attacks, developed pentesting products or other attack tools, participated in CTF competitions or authored CTF challenges, or participated in other types of security research & development.

  • Work well in a multidisciplinary team and can adapt to rapidly evolving challenges.

  • Care about the societal impacts of your work.
