About VulnCheck
Exploitation prevention is only as strong as the intelligence driving those efforts, and most of the industry is still running on intelligence that lacks exploit context. VulnCheck, The Exploit Intelligence Company, delivers structured exploit intelligence on what is actively weaponized in the wild, purpose-built for the data lakes, ETL pipelines, automation, and AI and LLM workflows your infrastructure already runs on, raising the capability of everything it powers.
About the Role
We’re looking for a Senior Vulnerability Researcher to join our agentic vulnerability discovery team. This role sits within our Initial Access Intelligence group, which delivers exploits, detections, and other artifacts designed for active cyber defense. You'll work with a seasoned team of hackers and threat researchers to find and weaponize new vulnerabilities across a range of operating systems, platforms, and devices — before adversaries do.
You'll drive original research from exposure analysis and reverse engineering through vulnerability discovery and weaponized exploit development. You'll also help push the state of the art in how VulnCheck finds bugs by applying novel agentic approaches to vulnerability discovery and exploit creation. This is a 100% remote role based 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. (And more, below!)
