## Description

We are seeking an experienced OT Security Platform Engineer / Technical Lead to own and operate the Dragos security monitoring platform across a global manufacturing environment. This is a hands-on technical leadership role responsible for platform health, sensor management, detection tuning, OT security triage, site onboarding, and network segmentation support. The role will also coordinate day-to-day activities of a small managed services team and provide OT security context to Threat Detection & Response teams. The ideal candidate will combine strong Dragos or equivalent OT monitoring expertise with ICS networking, security operations, and client-facing delivery experience.

In this role, you will:

 * Own day-to-day operations of the Dragos Platform, including sensors, SiteStore, OT Watch, platform health, upgrades, configuration consistency, and data quality.
 * Monitor and troubleshoot unhealthy or offline sensors, resolve data coverage issues, and coordinate technical issues with Dragos support and network teams.
 * Validate sensor placement, SPAN/TAP coverage, and passive network visibility across industrial environments while identifying monitoring gaps.
 * Triage high-severity OT security findings, validate affected assets, investigate potential benign activity, and escalate confirmed or suspicious events to the Threat Detection & Response team.
 * Tune Dragos detections to improve fidelity, reduce false positives, and ensure critical findings and OT Watch alerts are appropriately routed to enterprise security teams.
 * Support SIEM integration, detection forwarding, escalation workflows, and operational handoffs while providing OT-specific context for security investigations.
 * Deploy and validate Dragos sensors for new or acquired sites and manage secure decommissioning when facilities are closed or divested.
 * Support OT network segmentation initiatives by analyzing traffic patterns, planning sensor placement, and validating monitoring coverage following network changes.
 * Coordinate daily activities of managed services resources, manage escalations, and act as the primary technical point of contact for OT Security leadership.
 * Maintain operational runbooks, transition plans, escalation matrices, weekly status reports, monthly scorecards, service metrics, and knowledge-transfer documentation.
