## Description

Get to Know Us 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. We are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're 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. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results. What You'll Do We're looking for an Engineering Manager to lead our EDR remediation team. NodeZero proves which attacks work in a customer's production environment. This team closes the loop — turning what we learn from offense into defensive action. You lead a team of diverse skill sets and they work at different cadences and measure progress differently. Building an environment where those differences compound rather than collide is a central part of the job. You own hiring, growth, and how the team works together as it scales. You partner closely with a staff-level technical lead who owns architecture, with Product on sequencing, and with engineering leaders across the organization. This is a highly technical leadership role for someone who has moved beyond hands-on coding but still has the depth to evaluate a design, challenge an estimate, and know when a team is stuck. In this role, you will: 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. Partner with a staff-level technical lead who owns architecture, and with Product on roadmap and sequencing. Translate ambiguous goals into sequenced, deliverable work, and manage scope actively rather than absorbing it. Stay technically engaged enough to challenge assumptions and unblock the team, while creating outcomes through engineers rather than serving as the primary implementer. Establish the operational discipline this work requires: design review, release practices, on-call, and incident response. What You'll Bring 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. Track record delivering products under a fixed date, where requirements were ambiguous and scope had to be actively managed rather than assumed. Strong dependency and stakeholder management across many engineering teams, with a habit of surfacing risks and tradeoffs early and in writing. Understanding of security and reliability best practices in multi-tenant SaaS. Experience partnering with a staff-level technical lead, with a clear sense of where management ends and technical ownership begins. Ability to hold a quality or safety bar under schedule pressure, and to escalate scope tradeoffs rather than absorb them. Preferred Familiarity with agentic or LLM-backed systems in production, and a realistic view of how they fail. Background in security operations, detection engineering, or offensive security. Experience leading a platform team whose customers were other internal
