About us
National Grid Electricity Transmission (NGET) sits at the heart of the UK’s energy system. The reliability, safety, and resilience of our transmission network is critical to daily life, and protecting it against cyber threats is a core priority.
We are seeking a Lead OT Security Engineer to take ownership of cybersecurity for our Protection & Control (P&C) and substation automation environments. This role is intentionally suited to someone with a strong electrical or power systems engineering background who is passionate about developing deeper expertise in OT cybersecurity.
This role is subject to National Security Vetting (NSV). To be eligible, candidates will normally need to have lived in the UK for at least 5 years.
Job Purpose
As our network evolves, so too does the need to protect it from emerging cyber threats. We are looking for a Lead OT Security Engineer to strengthen cybersecurity across our Protection & Control (P&C) and substation environments.
This role is ideally suited to someone with a strong electrical or power systems engineering background — particularly within substations or P&C — who is looking to apply or develop their expertise in OT cybersecurity.
You will act as a subject matter expert at system level, helping us understand risk across substation environments, improve cyber resilience, and shape how we invest in protecting critical national infrastructure.
What you'll do
- Act as the technical lead for OT cybersecurity within substation and Protection & Control environments, ensuring secure-by-design delivery of engineering solutions
- Lead assessments of substation and P&C systems to identify cyber and engineering risks, working with teams to define practical, real-world improvements
- Own and develop the cyber assessment framework for P&C, including metrics, assurance, and regulatory reporting
- Work closely with design, protection engineering, commissioning, operations, and IT teams to embed security across the full engineering lifecycle
- Provide expertise across substation automation and control systems, including protection relays, engineering workstations, gateways, and OT networks (including IEC 61850 environments)
- Identify gaps in current cyber resilience and define clear, achievable remediation strategies
- Develop and maintain key assurance artefacts such as security cases, risk registers, and compliance evidence
- Act as business lead on cyber resilience projects (including Ofgem-funded programmes), ensuring outcomes are practical, effective, and adopted by the business
- Coach and support engineers in building consistent OT security practices across programmes
- Engage with internal stakeholders, suppliers, and industry bodies to continuously improve our cyber capability
