People Operations Lead

Get to Know Us

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 product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by IT Ops/SecOps teams, consulting pentesters, and MSSPs and MSPs.

We are a fusion of former U.S. Special Operations cyber operators, startup engineers & operators, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools and false positives, resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.

As a remote first company, we require minimum 25Mbps consumer grade broadband connection.

What You’ll Do

We’re looking for a People Operations Lead who can design and build the systems that scale. This is a highly specialized, hands-on role focused on People systems architecture, workflow automation, people analytics, and AI.

As Horizon3 continues to grow our operations are increasingly more complex, we need to move from reactive, manual work to scalable operating models that reduce noise, improve data reliability, and free the People team (and the business) to move faster. This role is designed to be a force multiplier, not incremental overhead, and will play a critical part in strengthening our operational foundation.

If you’re someone who can’t help but look at a process and think “we can automate this,” and you’re excited about building smarter systems that scale, this role is for you.

This role will be responsible for:

People Systems Architecture, Automation and Analytics

• Own and evolve our People systems across Rippling, Ashby, Deel, and key integrations/connection points.

• Design and automate core employee lifecycle workflows including onboarding, offboarding, job changes, manager changes, and org updates.

• Partner with IT / Business Systems as a peer to implement improvements quickly without relying on ticket-based execution for every change.

• Build and maintain a People Analytics dashboard that provides clear, executive-ready insights (e.g., headcount, attrition, hiring, workforce trends, and operational performance).

• Improve data quality and consistency across systems by defining clean data standards, validating inputs/outputs, and closing gaps.

AI Execution & Enablement

• Partner with the Sr. Director of People Operations and Head of IT and Security to execute on the People + company-wide AI strategy with an emphasis on real business value (not experimentation for its own sake).

• Build AI foundations including policies, documentation, governance/guardrails, training, and enablement.

• Identify high-impact AI opportunities across People Operations and adjacent business workflows, and turn them into pilots, automation projects, or durable operating solutions.

• Help standardize how the team evaluates AI opportunities, measures success, and scales what works.

Operations & Scale Readiness

• Partner with the broader People team to support core People Operations needs (including compliance, immigration, global mobility, and employee lifecycle changes), stepping in as needed to ensure high-quality execution and a consistent employee experience.

• Codify scalable workflows, best practices, and documentation.

• Strengthen operational readiness for growth across headcount, geography, compliance, and complexity.

• Support early foundations for IPO readiness and compliance muscle, including clean documentation, audit-friendly workflows, and strong operational controls.

What You’ll Bring

• Proven experience owning People Ops systems and automation at a scaling company

• Extensive experience working across HR systems, workflows, integrations, and process design

• Practical experience driving automation and/or AI-enabled wo
