Summary/Overview

At Horizon3.ai, we’re redefining the offensive cybersecurity space—and we need a forward-thinking, technically fluent Product Manager to own the SaaS platform capabilities that power our enterprise and MSP customers. This high-impact role will focus on user authentication, authorization models, organizational/tenant management, user settings, and auditability—ensuring our platform scales securely and effectively for the most demanding environments.

You’ll work closely with engineering, architects, and customer-facing teams to define and deliver enterprise-grade platform features that provide governance, security, and operational efficiency. From authentication and role-based access control to tenant hierarchies, user preferences, and comprehensive audit logging, you’ll set the strategy for the foundational elements of our SaaS platform.

This is a pivotal opportunity for a product leader who thrives at the intersection of system design, security, and enterprise customer experience. If you’ve led platform initiatives around RBAC, identity, tenant management, or compliance in high-growth SaaS environments, we want to hear from you.

What You’ll Do

• Own the SaaS Platform Vision – Define and drive the roadmap for authentication, authorization, user settings, tenant management, and auditability.

• Advance Authentication Capabilities – Deliver enterprise-grade identity features including SSO, MFA, passwordless login, and support for standards like OAuth and SAML.

• Evolve Authorization Models – Define and refine roles, permissions, and flexible RBAC/ABAC structures to support complex enterprise and MSP environments.

• Enable Org & Tenant Management – Build multi-tenant capabilities, tenant hierarchies, provisioning/de-provisioning flows, and delegated administration.

• Deliver Comprehensive Auditability – Ensure audit logs, activity tracking, and reporting provide transparency, compliance support, and operational visibility.

• Enhance User Settings & Preferences – Own the experience for user profile management, notification settings, personalization, and self-service account options.

• Champion Governance & Security – Translate enterprise compliance and administrative needs into features that balance usability with control.

• Work Cross-Functionally – Partner with engineering, security, and customer success to prioritize and deliver scalable, enterprise-ready platform features.

• Translate Complexity into Roadmaps – Break down deeply technical requirements into actionable development plans sequenced for both near-term impact and long-term scalability.

What We’re Looking For

• You’ve built and scaled SaaS platforms at high-growth companies, with a focus on enterprise or MSP customers.

• You’ve led initiatives around authentication, authorization, user settings, tenant management, or auditability.

• You’re comfortable owning deeply technical products—identity standards, RBAC/ABAC, SaaS governance models, and user-facing account settings.

• You think in terms of platforms and systems, not just features, and you balance security, usability, and scalability in every deci
