Horizon3 is a fast-growing remote cybersecurity company on a mission to help organizations proactively find, fix, and verify exploitable attack vectors before criminals exploit them. The flagship product, NodeZero, delivers production-safe autonomous pentests and assessment operations that scale across internal, external, cloud, and hybrid environments. NodeZero is used by ITOps/SecOps teams, consulting pentesters, MSSPs, and MSPs across organizations ranging from small educational institutions to government agencies and Global 100 enterprises. The company was founded by a fusion of former U.S. Special Operations cyber operators, startup engineers, and cybersecurity practitioners, committed to solving common security problems: ineffective tools, false positives and alert fatigue, blind spots, checkbox security culture, skills shortage, and expensive consultant lead times.

Your responsibilities include: - Customer Engagement: Meet with potential customers to understand their cybersecurity needs, challenges, and infrastructure to ensure product fit. - Product Demonstrations: Deliver live demos and proof-of-concept sessions tailored to specific prospect needs and concerns. - Solution Development: Collaborate with sales and product teams to design and refine solutions based on customer feedback. - Technical Training: Train the sales team on product technical aspects to enhance their selling effectiveness. - Feedback Loop: Relay field insights to product and engineering teams to drive continuous improvement. - RFP/RFI Support: Assist in answering technical sections of RFPs and RFIs. - Post-Sales Support: Occasionally assist with post-sales implementation to ensure customer satisfaction. This role is fully remote but may require up to 50% travel. Job-related travel expenses are reviewed and approved by your manager. REQUIREMENTS: - 5+ years of experience as a Pre-Sales Engineer or Solutions Architect in the cybersecurity domain - Deep technical expertise in cybersecurity products and services - Strong understanding of cyber threats, risk management, and cybersecurity solutions - Excellent verbal and written communication skills - Demonstrated ability to simplify complex technical topics for non-technical audiences - Highly collaborative with strong initiative - Fluency in English
