- • As a Sales Engineer (Central) at Horizon3.ai, you will serve as a trusted technical partner in mid-enterprise sales cycles, working closely with Account Executives to help organizations understand the technical and business value of the NodeZero platform, which enables proactive identification and remediation of exploitable attack vectors before criminals exploit them.
- • Your day-to-day responsibilities include leading discovery and technical qualification meetings with prospective customers to assess infrastructure, security maturity, compliance needs, and risk priorities; delivering tailored demos and proof-of-value engagements that connect platform capabilities to business outcomes; maintaining continuity through the customer lifecycle by tracking evolving needs and identifying expansion opportunities; translating technical depth into business value by framing results in terms of exposure reduction, compliance alignment, and operational efficiency; owning technical deal strategy by navigating objections and competitive positioning; collaborating cross-functionally with Product, Engineering, Customer Success, and Product Marketing to inform roadmap and positioning; supporting enablement by refining demo flows, technical assets, and playbooks; and owning post-close technical continuity to ensure smooth handoffs, reinforce value, and monitor adoption and expansion signals.
- • Horizon3.ai is a fast-growing, remote-first cybersecurity company founded by former U.S. Special Operations cyber operators, startup engineers, and frustrated cybersecurity practitioners, dedicated to solving pervasive industry challenges such as ineffective security tools, alert fatigue, blind spots, checkbox security culture, skills shortages, and the high cost and delay of external consulting.

- • In this role, you will deepen your expertise in cybersecurity sales engineering, master the art of translating complex technical concepts into compelling business narratives for both practitioners and executives, gain hands-on experience with autonomous penetration testing technology, strengthen your ability to drive structured proof-of-value engagements, and grow your influence in shaping product positioning and go-to-market strategy through direct customer feedback and cross-functional collaboration—positioning you for long-term impact in a high-growth, mission-driven security organization.
