OT Security Consultant

As the OT Security Consultant, you will be at the centre of how OT security is delivered across operational and industrial environments.

You will work directly with organisations to help them understand, manage and improve the security of their OT and industrial control systems, applying practical, experience-led approaches that reflect how these environments are designed and operated. The role involves close collaboration with engineering, operational and asset teams, ensuring security considerations are aligned with day-to-day operations.

You will contribute to site-based assessments and reviews, support the development of standards-aligned improvement plans, and advise on approaches that reflect regulatory expectations and industry good practice. The work is varied and hands-on, offering exposure to different environments, technologies and operational contexts.

This role is suited to someone who values technical rigour, collaborative working and the opportunity to contribute to the ongoing development of effective, practical OT security practices.

Our Industrial Automation & Control Systems (IACS) capability sits at the heart of how we support clients operating complex, safety-critical OT and ICS environments.

As part of this capability, you’ll join a community of OT and cyber security practitioners who work closely together across a variety of operational contexts. Consultants are trusted to operate autonomously on their engagements, while remaining connected to a wider network of experienced peers.

Knowledge and experience from live environments are shared openly, helping the community grow and evolve over time. This includes regular collaboration with other OT specialists, access to senior technical support, and opportunities to contribute to the development of standards, methodologies and ways of working across the practice.
