Senior Engineering Manager, Client Platform

The posting, as Horizon3 wrote it

Get to Know Us

Horizon3.ai http://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 NodeZero™ 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

You will lead Client Platform — the team responsible for the software that lives in customer environments and makes NodeZero's autonomous pentests possible. Client Platform owns two sub-teams: Image Build & Release (the factory that produces and signs the NodeZero runner container image) and OTA Services (the system that keeps runners current across thousands of customer environments). Every pentest NodeZero runs depends on this team's work being reliable, secure, and fast.

• Team Building & Culture: Build, mentor, and grow Client Platform to ~10 engineers across Image Build & Release and OTA Services. You will directly manage the Engineering Managers of both sub-teams and set the technical and cultural direction for the full org. Establish engineering norms and a culture of ownership for a team whose software runs in environments you cannot control.
• Image Build & Release: Lead end-to-end CI/CD workflows to create, sign, and reliably publish the NodeZero runner container image. Own software supply chain security: reproducible builds, image signing, SBOM generation, and vulnerability scanning in CI.
• OTA Services: Architect and operate the over-the-air update delivery system that keeps NodeZero runners current across thousands of customer environments — reliably, securely, and without requiring manual customer IT intervention.
• Security Research Partnership: Collaborate closely with Security Research to ensure the runner seamlessly executes new autonomous pentest capabilities as they ship.
• Act as a Product Owner: Partner with product managers, security researchers, and customer success to manage the client-side roadma
