About VulnCheck
VulnCheck is transforming vulnerability intelligence by helping security teams act faster and with more confidence. Our platform delivers early, high-quality exploit intelligence, deep asset correlation, and contextual insights to help organizations stay ahead of emerging threats.
About the Role
VulnCheck is looking for a Senior AI Software Engineer to design and build AI systems. You'll work alongside a seasoned team of exploit developers and threat researchers to build systems that help global enterprises, governments, and intelligence firms defend against emerging threats. This is not a wrapper around a chatbot. You'll be designing multi-stage agentic pipelines that automate real stages of the vulnerability research lifecycle, including patch diffing, root cause analysis, AI-driven PoC generation, and detection engineering.
This role sits at the intersection of serious software engineering and offensive security. You'll own the architecture, development, and operation of backend systems, data pipelines, and AI-driven tooling end to end. You won’t be writing exploits yourself. Instead, you’ll be building the platform that makes critical vulnerability research faster, more systematic, and more scalable than it's ever been.
This is a 100% remote role in the United States.
Why Join VulnCheck?
VulnCheck stands behind its mission to influence how organizations worldwide understand, assess, and remediate security vulnerabilities — and to deliver intelligence-based solutions that change the world.
You'll be joining a collaborative, supportive environment that values intellectual curiosity, technical mastery, and personal growth.
