Job Purpose
This role takes a lead in cyber asset management for Electricity Transmission (ET), ensuring cybersecurity risks are fully understood, assessed and effectively managed across our operational technology (OT) environments. By contextualising how cyber threats and vulnerabilities manifest within ET’s substations and control systems, you’ll translate cyber risk into robust asset management policies and investment priorities. You’ll provide expert input to ensure emerging threats are anticipated, mitigation strategies are effective, and asset decisions support both regulatory compliance and long‑term network resilience. Working closely with engineering, projects and design teams, you’ll play a key role in strengthening ET’s cyber maturity and protecting the transmission network.
What you'll do
* Lead the development of ET’s vulnerability management processes for OT devices
* Capture, assess and manage cybersecurity vulnerabilities and deviations from target state using an agreed risk framework
* Develop cybersecurity policies and technical specifications that reduce risk, improve organisational cyber maturity and support compliance with NIS regulations
* Engage with project and design teams to ensure cybersecurity requirements for OT devices are understood and built into solutions
* Communicate current cybersecurity risks and vulnerabilities clearly through appropriate reporting and stakeholder engagement
* Support the development of engineering justifications and business cases for investment in additional cybersecurity controls
* Provide subject matter expertise on emerging cyber threats and ensure effective mitigations are implemented across the ET estate
About you
You’re an analytical and forward‑thinking professional with strong technical understanding of OT environments and how cybersecurity risks impact operational electricity networks. You’re confident influencing technical audiences, comfortable challenging established approaches, and motivated to help the business mature its cyber and asset management capability.
* Experience introducing changes to technical specifications, standards or policies
* The ability to clearly communicate complex and sensitive cyber risks verbally and in writing
* A proactive mindset, comfortable breaking new ground and supporting changes to how decisions are made
* Strong understanding of OT assets and systems used in Electricity Transmission substations, particularly protection and control systems
* Experience applying structured risk assessment processes and frameworks
* Knowledge of operational practices used to manage and support OT assets
* A detailed understanding of how cybersecurity risks manifest across networks, devices and systems
* Sound understanding of asset management principles, including lifecycle management, risk‑based decision making and asset data
* Familiarity with international cybersecurity standards such as IEC 62443 and IEC 62351
What you’ll get
* Salary: £55,000–£68,000 per annum (dependent on experience).
* Discretionary annual bonus.
* Contributory pension — employer matches employee contributions up to 12% of salary.
* Flexible benefits including share incentive, salary‑sacrifice car and technology schemes, employee assistance and matched charity giving.
