General Engineering

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. Were looking for an Engineering Manager to lead our EDR remediation team. NodeZero proves which attacks work in a customers production environment. Building an environment where those differences compound rather than collide is a central part of the job. You partner closely with a staff-level technical lead who owns architecture, with Product on sequencing, and with engineering leaders across the organization. Lead, mentor, and grow a team of backend engineers and security practitioners with deep EDR expertise, with clear career paths for each.
Help the team turn EDR workflows into buildable requirements and usable product capabilities.
Familiarity with EDR or security operations sufficient to partner effectively with domain experts.
Proven experience leading highly technical backend or platform engineering teams — ideally within a SaaS, cybersecurity, or cloud-scale environment.
Strong dependency and stakeholder management across many engineering teams, with a habit of surfacing risks and tradeoffs early and in writing.
Ability to hold a quality or safety bar under schedule pressure, and to escalate scope tradeoffs rather than absorb them.
Background in security operations, detection engineering, or offensive security.
Experience leading a platform team whose customers were other internal engineering teams.
Exposure to event-driven architectures or streaming platforms (Kafka, Pulsar, Kinesis, Flink, or similar).
