Some flexibility for home working may be available, where appropriate.About us National Gas is securing Britain’s energy. We transport gas throughout Great Britain, repair and maintain gas pipelines, and manage the meters that allow millions of homes and businesses to access the energy they need. We are the national gas network, providing secure energy to power Britain, achieve net zero, and maintain our industrial competitiveness.About the role Shape the design and direction of critical infrastructure by defining how projects are engineered from the outset.

You’ll develop early-stage CAPEX project scopes across our mechanical and civil plant portfolio, bringing engineering insight and technical clarity that guides investment decisions and supports delivery through the full project lifecycle.

Why this role matters This role sits at the centre of a wide-ranging CAPEX programme that maintains and upgrades essential gas transmission assets. Your work ensures that projects are grounded in robust engineering design, accurate data, and clear feasibility from day one – supporting safe, reliable, and future-ready infrastructure.

You’ll take ownership of early-stage development while remaining connected to downstream design and delivery. By translating survey findings, operational requirements, and stakeholder input into well-defined technical scopes, you’ll help avoid risk, improve constructability, and drive better project outcomes across the programme.

This is a role for someone who combines strong engineering judgement with a practical approach to project development – someone who enjoys shaping solutions early, influencing stakeholders and seeing designs progress into delivery.What you'll be doing Develop clear, evidence-based project scopes for early-stage CAPEX interventions across mechanical and civil assets Evaluate optioneering and feasibility outputs to define preferred engineering and delivery solutions Produce structured project definition documents including cost inputs (with estimating teams), risks, assumptions, and programme impacts Analyse survey data and asset condition information from site visits to validate project drivers Plan and conduct site surveys to gather technical data, verify constraints, and assess risks Coordinate stakeholder input across engineering, operations, estimating teams, suppliers, and contractors Engage in Campaign Decision Panels (CDPs), aligning stakeholders to agree project direction and priorities Support AGI replacement and upgrade projects, contributing to scope development and technical decision-making Integrate constructability, safety, and delivery considerations through engagement with suppliers and contractors Maintain accurate project records to support seamless transition into detailed design and delivery phases Identify opportunities to improve and standardise early-stage project development approaches About you You’ll bring a strong engineering or design background, alongside experience contributing to project development in infrastructure or utilities environments. You’re comfortable working across disciplines, using technical insight to shape practical solutions and guide decision-making. You’ll be confident engaging stakeholders and translating complex data into clear, structured outcomes.
