Houston, TX - USA
Job Summary
The Senior OT Security Analyst is a hands-on cybersecurity professional responsible for strengthening the security and resilience of Fervos operational technology environments. The role partners with Operations OT and controls engineering project delivery IT enterprise cybersecurity compliance legal and third parties to translate OT security program objectives into durable technical controls operating processes and defensible evidence.
This analyst evaluates OT architectures and data flows supports secure commissioning and change management improves asset and configuration visibility governs remote and vendor access develops monitoring and incident-response capabilities and maintains risk and remediation records. The role applies NIST SP 800-82 Rev. 3 and IEC 62443 concepts and supports NERC CIP governance where applicable without independently determining regulatory applicability or certifying compliance.
ResponsibilitiesOT Program Governance and Risk
- Translate program objectives into execution. Develop and maintain practical OT security standards procedures control requirements checklists and review cadences that can be used by site engineering project and vendor teams.
- Maintain the OT risk lifecycle. Document risk scenarios operational consequences existing safeguards treatment plans owners due dates exceptions accepted risks and closure evidence.
- Support governance and assurance. Prepare status metrics decision records issue escalations control evidence and review materials for OT cybersecurity and compliance forums.
- Support NERC CIP readiness where applicable. Partner with Compliance and accountable business owners on asset scoping control ownership recurring evidence exception management and audit preparation; avoid unsupported compliance conclusions.
Asset Vulnerability and Configuration Management
- Improve OT asset awareness. Maintain or validate inventories for controllers RTACs HMIs historians engineering workstations network devices security appliances communications gateways and supporting services.
- Assess vulnerabilities in context. Evaluate exposure exploitability operational consequence compensating controls vendor guidance and outage requirements rather than relying on CVSS scores alone.
- Strengthen configuration control. Define secure baselines configuration backup expectations account and service reviews network rule reviews time synchronization and change records for critical OT components.
- Coordinate remediation. Work with asset owners and vendors to plan testing approvals maintenance windows rollback validation and closure evidence for patches and other risk treatments.
Monitoring Incident Response and Recovery
- Develop safe OT monitoring coverage. Identify priority log sources and passive network visibility points; support secure collection normalization alerting retention and documented blind-spot management.
- Investigate OT security events. Triage anomalies and alerts correlate technical evidence with operating conditions preserve records coordinate escalation and distinguish cyber activity from equipment or process faults.
- Advance response readiness. Maintain OT-specific playbooks contacts decision paths communications procedures evidence handling and interfaces with enterprise incident response and site emergency processes.
- Validate recovery capability. Support backup and restoration testing controller and network configuration recovery clean rebuild planning manual or degraded operating procedures and lessons-learned tracking.
