About EY:At EY, we are committed to building a better working world. Our Cybersecurity Consulting Practice is rapidly expanding, and we are investing in our capabilities to meet the increasing demand for cybersecurity solutions. Join us and be part of a global team of over 13,000 professionals dedicated to delivering cutting‑edge security transformation programs and services.

The Opportunity:As a Director in Cybersecurity, you will bring diverse perspectives and deep subject‑matter expertise to deliver high‑quality insights and outcomes for our clients. You will play a strategic leadership role in shaping and overseeing complex cybersecurity engagements, strengthening senior client relationships, and guiding teams to develop innovative, practical solutions that address the evolving security challenges organisations face.

Key Responsibilities:

• Lead and manage large OT Security engagements, overseeing day‑to‑day delivery across industrial environments including manufacturing, energy, utilities, and critical infrastructure. Ensure delivery meets quality, time and budget expectations while navigating complex OT operational constraints.
• Apply deep technical and sector knowledge across OT, ICSS, and IIoT environments to shape and deliver client programmes. Leverage expertise in IEC 62443, NIST CSF for OT, and the Purdue Model to conduct maturity assessments, design secure architectures, and lead OT cyber‑risk reduction initiatives.
• Identify, shape, and originate new OT security opportunities, using established industry relationships across engineering, operations, and cyber functions. Position the firm with senior OT decision‑makers, including engineering directors, CISOs, and asset owners, demonstrating a strong understanding of safety, reliability, and availability priorities.
• Partner with senior practice and market leaders to pursue high‑value OT‑security‑focused opportunities. Develop differentiated proposals, point‑of‑view materials, and transformation roadmaps aligned to industrial cybersecurity trends such as OT–IT convergence, zero‑trust for OT, asset visibility, and secure remote access.
• Provide visible leadership into a globally established high‑performing OT security team, sharing deep domain expertise in ICSS/SCADA, industrial protocols, and secure OT architecture patterns. Mentor consultants to develop both technical skills and commercial acumen, fostering a culture of continuous learning and cross‑disciplinary collaboration.
• Develop impactful OT cybersecurity thought leadership, articulating market‑relevant insights on IEC 62443 adoption, secure operations, industrial threat landscapes, and practical transformation strategies. Support the creation of frameworks and tools that differentiate the firm’s OT security offering.
• Build and maintain strategic relationships with senior client leaders, including operations executives, heads of engineering, CTOs, and CISOs. Use these relationships to identify transformation opportunities, influence senior stakeholders, and steer delivery outcomes across complex industrial ecosystems.

Skills and Attributes for Success:
