  • • The Mid-Market Account Executive at Horizon3.ai is a critical sales role focused on driving revenue growth by acquiring new customers and expanding the company’s presence in the cybersecurity market across Australia and beyond. This role is essential to scaling adoption of the NodeZero platform, which enables organizations to proactively identify and remediate exploitable attack vectors before they are exploited by threat actors.
  • • Day to day, the Account Executive will manage the full sales cycle — from prospecting and qualifying leads to delivering product demonstrations, negotiating contracts, closing deals, and managing post-sales engagement to ensure customer satisfaction and retention. They will also develop and nurture Channel Partner relationships, leverage CRM tools like Salesforce for pipeline forecasting, and collaborate with internal teams including support, success, and marketing to align on go-to-market strategies.
