Growth Marketing Manager

The Mission Every attack runs on internet infrastructure, and DomainTools maps that infrastructure better than anyone. For over 25 years, elite security teams have used DomainTools to spot malicious infrastructure before it's used against them. Today we're in an active growth phase: shipping new products, expanding our intelligence platform beyond its DNS roots, and building for AI-native security operations. Our platform covers domains, IPs, hostnames, SSL certificates, passive DNS, real-time threat feeds, and AI-native integrations, with visibility into 97% of the internet. Iris, DNSDB, our real-time feeds, and our new MCP Server power security teams at Fortune 500 companies, U.S. federal agencies, and leading SOCs. We're not chasing a category. We define it, and we're accelerating. The Opportunity DomainTools is at an inflection point: strong product-market fit, a fast-expanding platform, and a market moving toward AI-native security operations.
