Role:

As a Senior OT Threat Hunter on the OT Watch team, you will serve as a key contributor to a strategic and persistent threat hunting solution designed to identify adversaries operating within customer OT networks using the Dragos Platform. The technology solution provides deep access and visibility into ICS/OT environments, and our team are expected to leverage their expertise to uncover sophisticated threats and drive measurable improvements to the overall program. OT Watch prioritizes strategic views of suspicious activities, normal events, platform detections (also known as "notifications"), and analytical responses to these activities. In this role, you will independently lead hunting operations, act as an escalation point for the broader team, and collaborate cross-functionally with Intelligence, Services and and Engineering teams to continuously elevate detection and offering capabilities. You will also serve as a trusted advisor to customers during critical security events, delivering clear and actionable guidance.

Responsibilities:

Lead hands-on, hypothesis-driven threat hunts across industrial (ICS/OT) networks - working with Intelligence, R D, and Engineering to find adversaries and uncover attack patterns others miss. Act as the top escalation point for high-severity alerts, guiding OT Hunters and analysts, and communicating directly with clients about critical findings, remediation steps, and technical questions. Configure and optimize the Dragos Platform and hunt profiles for each customer environment to catch real threats while cutting down false alarms. Develop new hunting hypotheses and hunt content based on real operational experience, and give structured feedback to Detection Engineering and Intelligence teams to sharpen indicators, reports, and platform outputs. Dig into suspicious network activity, validate what triggers alerts, and contribute to clear incident summaries and custom reports for both technical and non-technical audiences. Create scripts, workflows, and tooling to make hunting faster and more repeatable, while mentoring junior team members in OT protocols, adversary tactics, and threat intelligence.

Qualifications:

Demonstrated experience in hypothesis-based threat hunting. Able to reason from an intelligence source to a testable hunt and successful investigation. Experience analyzing network telemetry and identifying behavioral deviations/anomalies (not solely endpoint-focused). Strong understanding of networking concepts (e.g., TCP/IP, firewalls, DNS, packet analysis). Experience with PCAP analysis, IDS/IPS, SIEM platforms, or other network traffic analysis tools in an OT context. Deep familiarity with adversary tactics, techniques, and procedures (TTPs) relevant to OT environments, including
