Government and Public Sector – Cybersecurity OT Manager

The opportunity
EY’s Government & Public Sector (GPS) Cybersecurity practice helps Federal, State, Local, and Education clients protect mission critical Operational Technology (OT), industrial control systems (ICS), and cyber physical infrastructure. We support organizations responsible for national security, public safety, energy, manufacturing, and critical services as they modernize operations, manage cyber risk, and improve resilience in environments where availability, safety, and reliability are paramount.
As an OT Cybersecurity Manager, you will serve as a technical and delivery leader for complex OT cybersecurity programs supporting government and critical infrastructure clients. You will shape and oversee multi-year initiatives focused on secure architecture, industrial network segmentation, monitoring and detection, system modernization, and operational resilience.
This role emphasizes executive level advisory leadership, end to end program ownership, and deep technical credibility. You will partner with client executives, engineering leaders, and operators to ensure cybersecurity capabilities are engineered, deployed, and sustained in ways that protect operations without disrupting mission execution.
Role summary
The OT Cybersecurity Manager supports the development, deployment, and maturation of OT cybersecurity programs, including industrial network security, asset visibility, monitoring and detection, remote access, and secure system integration. You will own delivery of OT cybersecurity capabilities across one or more engagements, advise senior client stakeholders on OT security operating models and architectures, mentor engineers and consultants, and contribute to practice growth through capture support, solution shaping, and thought leadership.
You will position OT cybersecurity as a foundational enabler of mission assurance, safety, and resilience, supporting Zero Trust principles adapted for OT, industrial modernization initiatives, and secure convergence of IT and OT environments across legacy and modernized systems.
This role is designed for a professional who understands how OT environments operate in the real world and how cybersecurity controls must be engineered, deployed, and sustained without disrupting operations.

Requirements

• Deep understanding of OT / ICS architectures, industrial networks, and cyber‑physical system dependencies.
• Proven ability to lead complex OT cybersecurity programs in live operational environments.
• Strong knowledge of industrial cybersecurity standards and frameworks, including NIST SP 800‑82, IEC 62443, and Zero Trust concepts adapted for OT.
• Ability to navigate legacy systems, vendor constraints, and operational risk tolerance.
• Executive‑level communication skills, with the ability to brief senior leaders and engage credibly with engineers and operators.
• Comfort operating in a consulting leadership role, managing delivery, risk, and client relationships simultaneously.
• Bachelor’s degree (or equivalent experience) in Cybersecurity, Computer Science, Information Systems, Engineering, Business, or a related field.
• 7-10 years of experience across OT cybersecurity, ICS engineering, industrial networking, or critical‑infrastructure environments.
• Demonstrated experience leading OT cybersecurity engineering or modernization programs, including architecture and delivery oversight.
• Hands‑on familiarity with industrial security technologies (e.g., OT monitoring platforms, segmentation controls, secure remote access).
• Experience working with critical‑infrastructure or government clients in regulated or mission‑critical environments.
• One or more relevant certifications (e.g., CISSP, CISM, GICSP, GRID, GMON, CCSP, or equivalent).
• Active secret clearance with eligibility for a TS/SCI
• Willingness to travel 20–50% based on client needs.

Responsibilities

• Lead the design, engineering, and implementation of OT cybersecurity solutions across industrial control systems (ICS), SCADA, DCS, PLC based systems, and cyber physical environments.
• Architect and validate industrial network segmentation using models such as Purdue / IEC 62443, including secure zones, conduits, DMZs, and remote access architectures.
• Design and integrate OT security technologies, including passive monitoring, sensors, asset discovery, secure remote access, firewalls, and logging solutions within operational constraints.
• Guide delivery teams through system development, integration, testing, and sustainment, ensuring cybersecurity controls align with operational, safety, and mission requirements.
• Advise client leadership on OT cybersecurity strategy, roadmaps, and operating models, including governance, roles, and lifecycle management.
• Support risk assessments, architecture reviews, and control validation aligned to frameworks such as NIST SP 800 82, NIST CSF, IEC 62443, and DoD / federal guidance.
• Collaborate with IT, engineering, operations, safety, and vendor stakeholders to ensure cybersecurity solutions are practical, effective, and operationally viable.
• Mentor and develop OT cybersecurity engineers and consultants, building depth in industrial security engineering and delivery execution.
• Contribute to practice growth through proposal development, capture support, reusable solution development, and thought leadership in OT cybersecurity.
