Growth & Demand Generation Marketing Manager

Location: Remote or Hybrid in Charlotte, NC

Industry: Open Source Software Security

Reports to: Chief Growth Officer

Kosai is on a mission to eliminate CVEs across a company’s entire open source software stack, regardless of version or type. The world runs on OSS, yet enterprises have been forced to rely on compensating controls, costly migrations, or simply accept risk. We’re changing that by delivering real security patches at scale, solving one of the most urgent and universal challenges in enterprise security.

This is a strategic and high-impact role within a fast-moving GTM organization. As a foundational hire at this stage of our growth, you will work directly with our Chief Growth Officer, owning demand generation, ABM, and content strategy to drive pipeline acceleration. You'll leverage automation, data-driven experimentation, and outbound marketing strategies to reach key stakeholders at our ICP. If you're passionate about growth marketing, sales alignment, and building a scalable GTM engine, this role is for you.
