About Horizon3.ai

Horizon3.ai is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find, fix, and verify exploitable attack vectors before criminals exploit them. Our flagship NodeZero platform delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments - serving organizations ranging from educational institutions to Global 100 enterprises.

About the Role

We are looking for a Senior or Staff Product Manager to join our Proactive Offense product group. This team is responsible for every pentest operation type that makes NodeZero the most powerful proactive security platform on the market.

You will own one or more offensive product areas (e.g., External Pentesting) end-to-end: defining what NodeZero attacks, how it attacks, and how it communicates consequences and business risk to defenders. You will work directly with engineering managers and a world-class team of offensive security engineers to ship capabilities that emulate real attacker behavior.

This role is ideal for someone who is energized by the attacker's perspective, thrives in a fast-moving environment, and wants to shape how AI-powered offensive security evolves. You will join a product team that operates with high autonomy, moves fast, and has direct access to company leadership and customers.

What You'll Do

• Own the product roadmap for your offensive product area(s), from discovery through launch and iteration, balancing customer impact, technical feasibility, and business value

• Define attack capabilities in collaboration with offensive security engineers, translating attacker techniques (CVE exploitation, credential pilfering, lateral movement, privilege escalation) into product requirements

• Drive consequence-first thinking: ensure NodeZero doesn't just find vulnerabilities but demonstrates the blast radius and business impact of every attack path

• Partner with Engineering leadership to align priorities, manage trade-offs, and ship on aggressive timelines

• Engage directly with customers and prospects - including SecOps practitioners and CISOs - to deeply understand how they use NodeZero and where it needs to go next

• Collaborate cross-functionally with security research, sales engineering, marketing, and customer success to support launches, competitive positioning, and commercial deals

• Define and track success metrics
