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

As a Customer Success Engineer (CSE) at VulnCheck, you will serve as a trusted technical advisor to our existing customers, helping them successfully adopt, integrate, and operationalize VulnCheck intelligence across their security programs. Customer Success Engineers at VulnCheck are product experts, implementation specialists, and long-term customer advocates. This role is focused on driving customer outcomes, ensuring deployments are successful, integrations are effective, and customers realize ongoing value from VulnCheck’s solutions. By deeply understanding customer environments and objectives, you will help turn VulnCheck from a data source into a core operational capability within their security stack. You will work closely with Enterprise, MSSP, and Cyber Vendor customers across the EMEA geography, partnering with Security Operations, Vulnerability Management, Threat Intelligence, and Engineering teams to embed VulnCheck into day-to-day workflows. You will play a critical role in ensuring customers not only deploy VulnCheck successfully but also continuously evolve how they use our intelligence to improve detection, prioritization, and response. Although this is a 100% remote role, candidates must be located in Cheltenham, UK for occasional onsite meetings with our federal and public sector customers.
