Lead Network Performance Engineer

About the role

National Grid Electricity Transmission (NGET) sits at the centre of the UK’s energy system. The electricity we deliver keeps the country moving, fuels businesses and schools, and brings energy to life for millions. As our national infrastructure evolves, so must the way we operate, plan and protect it.

In NGET, we’re committed to running a safe network and maintaining an exceptionally reliable quality of supply for our customers. Achieving this relies on strong network management—how we operate, plan, maintain and mitigate risk across our transmission system.

You’ll join our Network Resilience team, who are responsible for assessing and strengthening the system’s ability to withstand and recover from high‑impact, low‑probability events. The team ensures investment is focused where it’s most needed, helping our assets and wider network endure disruptive events and enabling faster, coordinated recovery.

As a Lead Network Performance Engineer, you’ll combine systems‑based analytical techniques with a deep understanding of electrical network operations to identify and quantify inherent risks across the transmission system. You’ll bring together data from multiple operational platforms to evaluate the likelihood and consequences of potential failure scenarios. Your insight will directly shape real‑time operational decisions while also informing long‑term planning and resilience investment strategies.

Key Accountabilities

• Apply systems engineering principles to analyse, quantify and enhance the resilience of the transmission network.
• Produce clear, accessible and insightful documentation on network risks to support operational decision‑making, incident response and long‑term strategic planning.
• Work closely with Post Event Analysis teams to identify trends, extract operational learning and evaluate emerging risks from significant events and incidents.
• Conduct detailed network criticality and vulnerability assessments to inform and validate security classifications for key assets.
• Support NESO and DESNZ with accurate reporting, metrics and analysis on network resilience risks and performance.

You’ll be based at our Warwick office up to twice a week, with the flexibility to combine this with hybrid working from home.

What you'll need

• An HNC/HND or degree in an Engineering or STEM‑related discipline.
• An understanding of Transmission or Distribution network operations and/or electrical power systems.
• Proven experience working with complex datasets and models, with the ability to interpret, evaluate and clearly present analytical findings.
• Excellent interpersonal and communication skills, with the confidence to influence, collaborate and constructively challenge across different teams and organisational levels.
• Strong planning, documentation and report‑writing abilities, capable of translating complex technical information into clear, concise outputs.
• Knowledge of Probabilistic Risk Assessment (PRA) techniques is desirable and would be a valuable asset in this role.
