Senior Malware Reverse Engineer Jobs in Colorado

Join a high-impact, mission-driven team operating at the forefront of cyber defense for critical infrastructure. As a Threat Hunter, you will be part of a small, agile group entrusted with proactively identifying and disrupting advanced threats targeting some of the nation’s most essential systems.

This role goes beyond traditional detection and response. You will lead and execute sophisticated threat hunting operations, transforming emerging intelligence into actionable hunt missions, engineering novel collection capabilities, and uncovering adversary activity that evades conventional security controls. Working at the intersection of cyber threat intelligence, detection engineering, and operational technology (OT), you will help defend complex, real-world environments where the stakes are tangible and immediate.

You will collaborate closely with system owners, engineers, and OT subject matter experts to design and deploy innovative approaches to visibility and analysis, often in environments where telemetry is limited and adversaries are highly adaptive. Your work will directly support federal missions, contributing to the resilience and security of critical infrastructure sectors.

This is a role for a technically deep, creatively minded operator who thrives in ambiguity, enjoys building new capabilities from the ground up, and is motivated by meaningful, national‑level impact.
