Role Overview

• The OT Security Engineer is responsible for securing Fervo’s industrial control systems, including SCADA, PLCs, HMIs, and associated control networks.
• Partner closely with engineering, operations, and IT teams to ensure cybersecurity is built into the design, deployment, and ongoing operation of all OT systems.
• Design and implement secure OT network architectures, including segmentation, firewalls, DMZs, and secure remote access
• Integrate cybersecurity controls into ICS and SCADA systems in alignment with standards such as IEC 62443 and NIST 800-82
• Develop and apply hardening standards for OT endpoints, including PLCs, HMIs, RTUs, and control servers
• Deploy and manage OT-focused security monitoring and visibility tools across control networks
• Implement and tune logging, intrusion detection, and anomaly detection for OT environments
• Collaborate with security operations teams to investigate, triage, and respond to OT security events
• Support forensic analysis, recovery, and post-incident review following cybersecurity events impacting OT systems
• Perform risk assessments and threat modeling for OT systems and development projects
• Coordinate vulnerability assessments and testing with OT stakeholders and vendors in a safe, controlled manner
• Support compliance with applicable cybersecurity frameworks and regulatory requirements
• Maintain documentation and support internal and third-party audits, including remediation tracking
• Lead security reviews for new OT deployments, vendor systems, and third-party integrations
• Work with operations teams to balance cybersecurity controls with safety, availability, and operational efficiency
• Train and support field engineers and operators on OT security best practices and secure system usage
• Contribute to the development of scalable OT security standards, patterns, and best practices across Fervo

Requirements

• 4+ years of experience in cybersecurity, with at least 2 years focused on OT or industrial control systems
• Strong understanding of industrial control environments, including SCADA systems, PLCs, HMIs, and control networks
• Working knowledge of industrial protocols such as Modbus, DNP3, OPC-UA, or PROFINET
• Experience designing and securing networks using segmentation models (e.g., Purdue Model)
• Familiarity with OT security monitoring, detection, or visibility platforms
• Ability to operate effectively in execution-focused environments where system uptime and safety are critical
• Preferred Experience working in energy, utilities, oil & gas, manufacturing, or other critical infrastructure sectors
• Hands-on experience with automation platforms from vendors such as Siemens, Rockwell, Schneider, or ABB
• Experience implementing secure remote access and managing third-party vendor connectivity in OT environments
• Professional certifications such as GICSP, GRID, CISSP, or ISA/IEC 62443
• Experience supporting greenfield or first-of-a-kind industrial system deployments
