Job Description
We are seeking a skilled OT Security Analyst to join our client's team supporting critical industrial environments in Houston, TX. In this hybrid role, you will be responsible for administering and supporting OT cybersecurity platforms and processes, with a primary focus on asset visibility, vulnerability management, and regulatory compliance. You'll work at the intersection of IT and operational technology — helping to protect infrastructure that keeps energy and utility systems running safely and reliably.
Day-to-day, you will administer key OT security tools including Industrial Defender and the Dragos Platform, manage configuration change monitoring, track and remediate vulnerabilities, and support incident response when needed. You'll develop dashboards and reporting to keep stakeholders informed on risk posture and compliance status. This role exists because of the growing criticality of OT security in regulated environments — the right person will help strengthen the security posture of industrial control systems at scale.
You'll collaborate closely with engineering, operations, regulatory, and IT/OT security teams, and will report into the OT security leadership function. The ideal candidate is passionate about critical infrastructure protection, thrives in technically complex environments, and brings both deep tool expertise and strong communication skills to navigate cross functional stakeholder relationships.
