Gray Swan is an AI security company that builds a research-backed platform to protect AI deployments across the entire lifecycle, offering input/output filtering, continuous monitoring, automated vulnerability testing, and enterprise-focused red-teaming services. The company combines frontier research, benchmarks, and large-scale red-team competitions to discover emerging attacks and deliver adaptive, integrable protections for AI agents, models, and connected tools. Gray Swan’s products and services are aimed at enterprises, AI labs, and security researchers seeking pre-deployment assessments, post-deployment monitoring, and compliance-ready defenses.

📋 Description

• Design and lead adversarial evaluations of frontier LLMs for biological misuse risks, including agent acquisition, pathogen characterisation and enhancement, biosecurity screening bypass, and emerging biotechnology capabilities across text, agentic, and multimodal systems • Partner with machine learning engineers and AI researchers to translate biological expertise into technical requirements for scalable evaluation datasets, classifiers, guardrails, benchmarks, fine-tuned models, and automated red-teaming • Develop and maintain the B in Gray Swan's CBRN harm taxonomy • Produce technical risk assessments and actionable recommendations for frontier AI labs, enterprise customers, policymakers, and internal stakeholders • Build, mentor, and lead a team of biology subject matter experts while establishing evaluation standards, quality processes, and scalable safety infrastructure • Represent Gray Swan as the company's biology safety expert through collaborations with AI labs, biosecurity organizations, government partners, and the broader AI safety research community
