• Provide technical oversight of the overall security architecture within Transmission, helping to ensure strong alignment and close collaboration where responsibilities meet across teams.
• Continually enhance our security standards so that expectations are clear, practical, and achievable, while working in partnership with teams across SSE to adopt common approaches and suggest improvements to group policies and standards.
• Make thoughtful, risk based decisions to ensure security standards are proportionate and balanced alongside wider business priorities, including delivering a network for net zero.
• Support the wider security team in strengthening our overall cyber capability and meeting the requirements of the Network and Information Systems (NIS) Regulations 2018 and the National Cyber Security Centre’s (NCSC) Cyber Assessment Framework (CAF).

You have

• Experience defining, implementing, and testing security controls and requirements aligned to recognised international standards within an Operational Technology environment, including direct experience securing systems across all Purdue levels.
• Experience leading a team of technical experts, including supporting performance and development, and helping to navigate differing viewpoints constructively.
• The ability to assess risks associated with control weaknesses across multiple systems and communicate clear recommendations for mitigation or acceptance to leadership and non technical audiences.
• Experience working within electricity transmission or another regulated utility environment.
• Recognised academic qualifications in a STEM subject, alongside relevant cyber security certifications in operational technology.
