As a Senior Backend Engineer on the Security Controls team, you’ll drive the technical vision for EDR telemetry and detection inside NodeZero, with direct influence over how EDR effectiveness and tuning evolves as a core 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, and scale effectiveness insights.
