Engineering Manager, Partner Integrations

Horizon3 is a fast-growing, remote cybersecurity company dedicated to the mission of enabling organizations to proactively find and 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 ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.
Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. Were committed to helping solve our common security problems: ineffective security tools, 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. You will lead Partner Integrations — the team that ships NodeZeros first-party integration products. When a customer wants NodeZero findings flowing into Crowdstrike, SentinelOne, Splunk, or any other security platform they run, your team builds that integration, ships it, and keeps it working. Each integration is a delivered product: it must install without friction, stay current as upstream APIs evolve, and carry the same quality bar as NodeZero itself. You will grow this team to 6–7 engineers and build an integration portfolio that makes NodeZero indispensable inside every customers security stack.

Experience leading engineering teams of 5–8 people building and shipping third-party integration products in a SaaS or security context.
Hands-on familiarity with the APIs and data models of enterprise security platforms — EDR (Crowdstrike, SentinelOne), SIEM (Splunk, Sentinel), ticketing (ServiceNow, Jira), or similar.
