The following sections consist mainly of a series of questions related to specific skills/job requirements. You should focus on the role rather than the individual when considering the most appropriate answer and should base the response on what you consider to be the normal features of the job which are typical of the job and its usual working conditions over the year.

SKILLS & JOB REQUIREMENTS (Please Complete Where Applicable)

Strategic Responsibility

As the OT Security Engineer within our supply chain IoT and Operational Technology environments: to help input into Information Security team and the continual improvement processes we strive to implement, as well as the resulting Security Improvement Plan, we aim to deliver. This is done through GAP Analysis work which is key to identifying weaknesses and opportunities to improve, as well as the assessment of new technology stacks such as AI and opportunities for Domino's Pizza Group (DPG) to benefit from them.

Problem solving

Ability to assess and solve complex problems (e.g. managing the identification and containment of a quickly- evolving cyber threat when limited information is known), analysing multiple sources of information to determine the best course of action whilst being in high pressure situations. This skill is particularly critical during a cyber security incident, where time is of the essence and a clear head is needed. Most decisions will be within predefined frameworks, but owing to the nature of OT incidents and the recovery time, non-programmed decisions may need to be made.

Decision making

Cyber security risk, within the SCC's, may have a wider business impact. A level of business-critical decision making is necessary, as an incorrect decision could result in significant business disruption and financial loss to DPG. This skill aligns to the problem-solving qualities and results in sound and decisive actions being taken.

Communication

Effective communication skills are required for this role to articulate both the technical and non-technical aspect of the role. Close working relationships must be forged with multiple stakeholders, from both operational and technical functions within Domino's. As the OT Security Engineer, you will be able to help on incidents in a calm and measured way and communicate effectively with key stakeholders at all levels, including Senior Management.

Innovation

Where there are opportunities to innovate then the OT Security Engineer will be able to. Although this role is aligned to helping keep Domino's safe from cyber-attack, there will be opportunities to help improve processes and implement new ones.

One such example is the use of new and evolving technologies, such as Artificial Intelligence, both to support the business use of such technologies in a secure way, but also to harness the technologies to enhance our security capabilities in innovative ways. Closely working with other IT teams, such as Infrastructure, to deploy new technologies that have a wider business impact.

Please summarise the levels of minimum education, knowledge, skills and experience this position requires (e.g., if you would be recruiting to fill this position, what aspects of background or knowledge would you expect a successful job applicant to have?)
