• Conduct security acceptance testing and validation of new or updated OT systems to ensure compliance with security requirements and industry best practices.

Risk Assessment & Vulnerability Management

• Perform consequence-based risk assessments for OT environments, utilizing methodologies such as Cyber Process Hazards Analysis (Cyber PHA) to identify, analyze, and prioritize cyber risks.
• Lead vulnerability management efforts for OT/ICS assets, including the use of Claroty for vulnerability identification, risk scoring, and remediation planning.
• Support clients in achieving regulatory compliance and readiness for audits related to OT/ICS cybersecurity.

Incident Response & Monitoring

• Design and implement OT/ICS security monitoring solutions, leveraging tools such as CrowdStrike for endpoint and network monitoring, and Splunk for log aggregation and analytics.
• Collaborate with IT and OT teams to develop and test incident response plans specific to industrial environments.
• Integrate monitoring and alerting workflows with ServiceNow for streamlined incident management.

Governance, Policy, and Training

• Develop and update OT/ICS cybersecurity policies, standards, procedures, and job aids.
• Deliver training and awareness programs for client personnel, including plant operators, engineers, and third-party vendors.
• Advise clients on governance frameworks and best practices for OT/ICS cybersecurity program development and maturity assessments.

Client Engagement & Leadership

• Serve as a subject matter expert in client meetings, workshops, and presentations, especially regarding the deployment, integration, and optimization of OT/ICS security tools.
• Lead project teams, mentor junior staff, and contribute to business development activities such as proposal writing and solution development.
• Stay current on emerging OT/ICS threats, vulnerabilities, and technologies, and share insights with clients and internal teams.

Required Qualifications

• Bachelors degree in Engineering, Computer Science, Information Security, or related field.
• 7+ years of experience in OT/ICS cybersecurity, including hands-on experience with industrial control systems (e.g., SCADA, DCS, PLCs) in sectors such as oil & gas, energy, utilities, or manufacturing.
• 4+ years of demonstrated experience designing and implementing OT/ICS security architectures and controls using tools such as Claroty, Palo Alto, Cradlepoint, CrowdStrike, BeyondTrust PRA, and familiarity with Cisco, ServiceNow, Splunk, and TxOne.

• Limited visa sponsorship may be available

• Ability to travel up to 50%, on average, based on the work you do and the clients and industries/sectors you serve, primarily within the Houston region.

Preferred Qualifications

• Advanced degree preferred.
• Professional certifications such as GICSP, CISSP, CISM, ISA/IEC 62443, or equivalent.
• Strong knowledge of OT/ICS protocols (e.g., Modbus, DNP3, OPC, Profibus), network architectures, and common vulnerabilities.
• Experience with cloud-based OT/ICS security solutions and IT/OT convergence initiatives.
• Experience with OT/ICS cybersecurity technologies for asset discovery, vulnerability management, network monitoring, endpoint protection, and privileged access management.
• Familiarity with industry standards and frameworks (e.g., NIST 800-82, IEC 62443, NERC CIP).
• Experience conducting risk assessments, vulnerability management, and incident response in OT environments.
• Strong communication skills, with the ability to present complex technical concepts to both technical and non-technical audiences.
• Demonstrated leadership in project delivery and client engagement.
• Prior consulting experience with a focus on critical infrastructure or industrial sectors.
• Experience developing and delivering OT/ICS cybersecurity training programs.
