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
VulnCheck is hiring a Principal Threat Hunter to discover, investigate, and document real-world exploitation and attacker infrastructure, and turn those discoveries into durable improvements to VulnCheck's detection capabilities.
VulnCheck operates infrastructure across the internet that gives us a direct view into attacker activity. Canary Intelligence deploys intentionally vulnerable systems and captures real exploitation attempts, giving researchers a steady stream of attacker binaries, source infrastructure, payloads, and exploitation techniques. Target Intelligence maintains a continuously updated view of internet-facing systems, including their exposure to known vulnerabilities and their relationships to scanners, proxies, C2 infrastructure, and other attack infrastructure.
Together, these datasets provide a foundation for research that is difficult to replicate elsewhere. You can observe exploitation as it happens rather than infer it from secondary telemetry, analyze what attackers deploy after gaining access, and pivot from an attacking host into the broader infrastructure behind it.
The role spans the full research process. You will hunt for interesting activity, investigate what you find, develop methods and detections to identify similar activity at scale, and turn those investigations into original threat intelligence. You will help build the tooling and detections needed to support your research and improve VulnCheck's ability to identify meaningful attacker activity.
You will be the first full-time threat hunter at VulnCheck, so there is no existing threat hunting pipeline or playbook to inherit. You will have substantial latitude to define areas of research and help establish how VulnChe
