Irregular

About Irregular Irregular is the first frontier security lab with the mission of protecting the world in the time of increasingly capable and sophisticated AI systems. We build next-generation defenses through high-fidelity research platforms that simulate and monitor real-world AI security scenarios. As AI systems become more powerful, we focus on staying ahead of emerging threats and vulnerabilities, ensuring these transformative technologies can be deployed safely and securely. About the Role 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.

As AI systems become more powerful, we focus on staying ahead of emerging threats and vulnerabilities, ensuring these transformative technologies can be deployed safely and securely. About the Role As a Technical Policy researcher at Irregular, you'll tackle some of the biggest and most complex questions of AI development and deployment. Your work outlining problems, solutions and principles for governments, frontier labs, and deployers will shape the emerging field of AI security. Representative projects: * Threat modeling and fleshing out in what specific way could a strong cyber-capable model cause harm. * Taxonomies for dangerous AI capabilities or mitigations. * Policy proposals for models' refusal policy (which prompts models should refuse to follow). * Following up on publications and news on AI policy, AI risks and mitigations, and technical AI research. * Writing academic papers and blog posts detailing our research around evaluation theory or mitigation recommendations. * Publishing your research and/or delivering research to our customers. You may be a good fit if you have * Strong research skills in both quantitative and qualitative methods. * Strong writing skills, and experience as an academic (or industry equivalent) writer or analyst. * Interest in AI and specifically AI security. * Technical proficiency. * Background in AI/cybersecurity - a big advantage
