Staff Software Engineer, Security Controls Telemetry & Detection
Get to Know Us
Horizon3.ai 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.

We are hiring a Staff Software Engineer to own the technical vision for EDR telemetry and detection work inside NodeZero and ultimately, the future of EDR effectiveness and tuning as a product capability. Modern endpoints are instrumented by CrowdStrike, SentinelOne, Microsoft Defender, Carbon Black, and others. Our customers need to know, with evidence, which of our attack techniques their EDR caught, which ones slipped through, and why. Answering that at scale — across platforms, tenants, and operator objectives — requires someone who deeply understands the telemetry surface and can turn that understanding into a product. Over time, this role will own the technical work for incorporating AI and ML research into how we reason about detection gaps, generate tuning recommendations,...
