About the Role:

As a Senior OT Threat Hunter on the OT Watch team, you will play a key role in delivering Dragos’ proactive threat hunting service, focused on identifying adversary activity within customer OT environments using the Dragos Platform. Leveraging deep visibility into OT networks and your industrial domain expertise, you will uncover sophisticated threats and help drive continuous improvements to the threat hunting program. You will independently lead hunt operations, serve as an escalation point for the team, and collaborate closely with Intelligence, Services, Product, and Engineering partners to enhance detections and overall capabilities. You will also act as a trusted advisor to customers during critical security events, providing clear, actionable guidance grounded in technical analysis.

Responsibilities:

Lead independent, hypothesis‑driven threat hunting operations across customer ICS/OT environments, investigating suspicious network behaviors to identify adversaries, anomalies, and misconfigurations.
Serve as the primary escalation point for high‑severity events detected in the Dragos Platform, guiding OT Hunters and Security Analysts through triage, analysis, and response.
Communicate critical findings directly to customers, providing clear, actionable remediation guidance and confidently addressing technical questions during security events.
Tune and optimize Dragos Platform configurations and distributed hunt profiles to improve detection fidelity, reduce noise, and validate detection triggers based on operational findings.
Develop and refine original hunt hypotheses, content, and workflows, and provide structured feedback to Detection Engineering and Intelligence teams to enhance detections, IOCs, and threat intelligence outputs.
Contribute to operational reporting and incident summaries, support custom reporting needs, and mentor junior team members to promote technical rigor, knowledge sharing, and continuous improvement across the team.

Qualifications:

5+ years of experience in threat hunting, security monitoring, or incident response within ICS/OT environments.
Strong understanding of networking concepts (e.g., TCP/IP, firewalls, DNS, packet analysis) and OT-specific protocols (e.g., Modbus, DNP3, Ethernet/IP).
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 MITRE ATT&CK for ICS.
Familiarity with threat intelligence workflows, including consumption and feedback loops with intelligence and detection engineering teams.
Proven ability to communicate complex security findings to clients and internal stakeholders, both verbally and in writing.
Experience acting as a technical escalation point or senior contributor in a security operations or threat hunting context.
Ability to work independently and lead efforts in a remote, distributed team environment.
