Director Operational Technology Cyber Security information

What does a director of operational technology cyber security do?

A Director of Operational Technology (OT) Cyber Security is responsible for overseeing and managing the security of systems that control industrial operations, such as manufacturing, energy, and utilities. Their primary focus is to protect critical infrastructure from cyber threats by developing strategies, implementing security controls, and ensuring compliance with regulations. They collaborate with IT and OT teams to assess risks, respond to incidents, and provide cybersecurity training. Additionally, they stay updated on emerging threats and technologies to keep the organization's operational systems secure.

How does a director of operational technology cyber security typically collaborate with other departments to enhance organizational security?

A Director of Operational Technology (OT) Cyber Security works closely with teams across IT, engineering, operations, and compliance to develop and implement robust security frameworks. They regularly coordinate with plant managers, network engineers, and risk management professionals to identify vulnerabilities and ensure that security protocols align with both business objectives and regulatory requirements. Effective communication and cross-functional teamwork are essential, as the Director must bridge the gap between traditional IT security and the unique needs of OT environments, often leading cross-departmental incident response exercises and security awareness training.

What are the key skills and qualifications needed to thrive as a director of operational technology cyber security, and why are they important?

To thrive as a Director of Operational Technology Cyber Security, you need deep expertise in cyber security principles, OT systems, risk management, and typically a bachelor’s or master’s degree in information security or a related field. Familiarity with industrial control systems (ICS), SCADA platforms, NIST or ISA/IEC 62443 frameworks, and certifications such as CISSP or GICSP is highly valued. Strong leadership, strategic thinking, and effective communication are crucial soft skills for guiding teams and collaborating with stakeholders. These skills and qualifications are vital to protect critical infrastructure, ensure regulatory compliance, and lead proactive security initiatives in complex OT environments.

What is the difference between Director Operational Technology Cyber Security vs Cyber Security Manager?

AspectDirector Operational Technology Cyber SecurityCyber Security Manager
CertificationsCISSP, CISA, CISM, GIACCISSP, CISA, CISM, GIAC
Work EnvironmentOversees OT systems in industrial, manufacturing, or utility sectorsFocuses on IT security across various organizational departments
Industry UsageCommon in industrial, energy, manufacturing sectorsWidespread across all industries including finance, healthcare, and tech
ResponsibilitiesStrategic OT security, risk management, complianceOperational security, incident response, team management

The main difference is that the Director Operational Technology Cyber Security focuses on securing industrial control systems and OT environments, while the Cyber Security Manager handles broader IT security operations. Both roles require similar certifications but differ in their scope and industry focus.

Job description

SpaceXAI's mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company's mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

ABOUT THE ROLE:

SpaceXAI is seeking an exceptional Operational Technology (OT) Engineer to own the design, implementation, optimization, and long-term reliability of industrial control and monitoring systems across our next-generation hyperscale data center campuses and co-located power generation facilities. You will architect and deliver resilient OT infrastructure supporting BMS, EPMS, SCADA, PLC, and related OT systems capable of supporting ultra-dense AI compute loads, massive power infrastructure, and aggressive deployment timelines that redefine industry standards. This is a high-impact, high-ownership role for an exceptional engineer who thrives in fast-paced, technically demanding environments. You will combine deep expertise in industrial automation, control systems, and mission-critical infrastructure with exceptional speed of execution, while seamlessly collaborating across mechanical, electrical, facilities operations, networking, and construction teams to deliver the control backbone that powers the future of AI.

RESPONSIBILITIES:
  • Own end-to-end OT critical infrastructure design, programming, configuration, commissioning, sustainment, and ongoing optimization. Deliver high availability OT infrastructure for critical hyperscale cooling & power control systems, including datacenter facility networks (MDFs/IDFs), industrial control networks (PLCs, turbines, etc.), and server rooms with switches/hosts/virtualization.Provide on-call network infrastructure support for BMS, EPMS, SCADA, PLC, and related systems (connectivity, addressing, protocol transport, troubleshooting at Layers 1–3/4).
  • Hands-on design and sustainment of Juniper fiber/copper networks in OT/facility environments (EX/QFX series preferred), including segmentation, VRFs, and integration with industrial control networks.
  • Design, implement, and secure OT networks and communications (BACnet, Modbus, OPC UA, MQTT, Ethernet/IP, and related protocols) while driving robust segmentation, monitoring, and cybersecurity practices.
  • Drive cross-functional multidisciplinary coordination with mechanical, electrical, structural, facilities operations, IT/OT networking, and construction teams to ensure seamless integration of control systems with overall campus infrastructure.
  • Perform advanced troubleshooting, root-cause analysis, and continuous improvement of OT systems to maximize availability, and operational resilience.
  • Deliver rapid, high-quality responses to field issues, design reviews, RFIs, and operational needs while maintaining rigorous documentation, change control, and design intent.
  • Identify and implement innovative solutions in industrial automation, advanced monitoring, predictive analytics readiness, and standardized control architectures to support SpaceXAI's aggressive growth trajectory.
  • Mentor junior engineers and technicians and contribute to the continuous improvement of SpaceXAI's OT design standards, programming standards, and best practices for mission-critical facilities.
BASIC QUALIFICATIONS:
  • Bachelor's degree in Controls Engineering, Automation Engineering, Electrical Engineering, Mechatronics, Computer Engineering, or a related technical field (or equivalent practical experience).
