The opportunity

Organizations are connecting industrial operations, modernizing control environments and integrating OT with enterprise technology. These changes create new cybersecurity, resilience and regulatory challenges across critical infrastructure and industrial sectors.

As an OT Cybersecurity Senior Manager in Technology Consulting, you will lead client engagements that assess, design and improve cybersecurity for Operational Technology and Industrial Control System environments. You will combine practical OT security knowledge with engagement leadership, client advisory, team development and business development. You will work across engineering, operations, cybersecurity and technology teams to help clients protect critical operations while supporting safety, availability and reliability.

Your key responsibilities

• Lead OT cybersecurity engagements, including maturity and risk assessments, architecture and configuration reviews, vulnerability assessments, security strategy, transformation roadmaps and implementation support.
• Assess industrial environments that may include ICS, SCADA, DCS, PLC, RTU, HMI, SIS and IIoT technologies, industrial networks and supporting infrastructure.
• Guide the design and implementation of practical OT security controls, including network segmentation, zones and conduits, defense in depth, system hardening, secure remote access, asset visibility, security monitoring and incident response capabilities.
• Apply recognized OT cybersecurity frameworks and standards, including ISA/IEC 62443 and NIST SP 800-82. Apply NIST CSF and sector-specific requirements when relevant to the client environment.
• Lead client workshops and technical discussions with operational, engineering, cybersecurity and executive stakeholders. Translate technical findings into clear operational and business risk implications.
• Manage engagement scope, workplans, resources, risks, quality, timelines and budgets. Keep client and EY stakeholders informed of progress and expected outcomes.
• Lead, coach and develop engagement team members. Review deliverables and promote a collaborative, quality-focused and safety-aware working environment.
• Build trusted client relationships and identify opportunities where EY can provide additional value.
• Support business development through proposals, client presentations, solution shaping, methodology development, thought leadership and reusable assets.
• Stay current on OT threat activity, industrial vulnerabilities, evolving regulations, security technologies and leading practices.

Skills and attributes for success

• Deep understanding of OT and ICS cybersecurity principles and the operational priorities that distinguish industrial environments from enterprise IT.
• Ability to lead complex client engagements and communicate with plant, engineering, security and executive stakeholders.
• Working knowledge of industrial network architectures, industrial protocols and security controls used in OT environments.
• Ability to turn technical observations into practical, prioritized recommendations that consider safety, availability, reliability and business continuity.
• Strong project management, analytical, problem-solving, facilitation, written communication and presentation skills.
• Ability to work effectively with multidisciplinary and geographically distributed teams.

To qualify for the role, you must have

• Bachelor's degree in Cybersecurity, Computer Science, Information Technology, Engineering, Industrial Automation or a related field, or equivalent relevant experience.
• Approximately 8+ or more years of relevant cybersecurity, OT security, industrial automation or related experience.
• Experience leading or managing OT cybersecurity assessments, architecture reviews, security improvement programs or implementation initiatives.
• Practical knowledge of OT and ICS environments, industrial networking and systems such as SCADA, DCS, PLC, RTU or HMI.
• Experience applying ISA/IEC 62443, NIST SP 800-82 or comparable OT cybersecurity guidance.
• Experience developing high-quality client reports, presentations, roadmaps, security designs, policies, standards or implementation documentation.
• Experience leading teams, managing client expectations and delivering work within agreed timelines and budgets.
• Ability and willingness to travel based on client and project needs.

Ideally, you'll also have

• Hands-on experience with OT monitoring, asset visibility or threat detection platforms such as Nozomi Networks, Claroty, Dragos, Armis, Microsoft Defender for IoT, Cisco Cyber Vision or comparable technologies.
• Experience in one or more industrial sectors such as power and utilities, oil and gas, manufacturing, chemicals, mining, transportation, water or other critical infrastructure.
• Experience with OT incident response, cyber resilience, threat modeling, security testing or vulnerability management in industrial environments.
• Relevant certifications such as GICSP, ISA/IEC 62443, GRID, CISSP, CISM, CISA, CCNA or comparable credentials.
• Experience supporting pursuits, proposals, account development, methodology development or practice-building activities.
