Senior Power System Engineer

National Grid is hiring a Senior Power System Engineer - This position is based from our Warwick office however we offer flexible hybrid working options.

You will develop into a highly capable transmission planning engineer, building expertise in strategic network assessment, system modelling, and Net Zero network development while contributing to some of the most significant transmission investment decisions in Great Britain.

As a Senior Power System Engineer within the Net Zero Engineering team, you will lead the technical assessment of future electricity transmission network requirements to support the decarbonisation of Great Britain's energy system. You will play a key role in identifying network needs, assessing system capability, developing innovative solutions, and providing robust engineering evidence to inform major transmission investment decisions.

Working across National Grid Electricity Transmission, NESO, customers, regulators, and industry stakeholders, you will lead strategic studies that support long-term network development, enabling the integration of renewable generation, large-scale demand growth, electrification, and emerging technologies.

You will combine advanced power system engineering expertise, modelling, analytics, and strategic thinking to ensure the future network can deliver Net Zero outcomes safely, efficiently, and economically.
