About the role

As a Senior Welding Engineer, you'll provide technical leadership across welding engineering, materials, non-destructive testing (NDT), pipeline integrity, and repair activities that help keep Britain's energy infrastructure safe, reliable, and resilient.

We're recruiting for opportunities across several areas of National Gas, giving you the chance to apply your expertise where it can have the greatest impact on the operation, maintenance, and future development of critical national infrastructure.

Why this role matters

The UK's gas transmission network is critical to energy security. This role helps ensure the safe operation, maintenance, development, and future evolution of the assets that millions of homes and businesses rely on every day.

You'll provide expert guidance on complex engineering challenges, influence technical decisions, develop industry-leading standards, and help shape how National Gas delivers safe, efficient, and innovative solutions now and for the future.

Where you could make an impact

National Gas Services (NGS)
