Senior Substation Main Plant Specialist; Drawing Office

Location: Cambuslang/Hybrid Working

Salary: From £55,000 + Excellent Benefits

Closing Date: 23rd July 2026

Scottish Power’s Drawing Office is expanding to support growing investment across the Transmission Network, and we are seeking a Senior Substation Main Plant Specialist to join our team.

In this role, you will be a technical focal point for the production and coordination of substation plant design deliverables, playing a key role in the development of transmission infrastructure projects from concept through to construction.

Your primary focus will be the creation, development, and assurance of detailed plant design drawings for high‑voltage substations, including equipment layouts, general arrangements, sections, elevations, busbar arrangements, equipment clearances, and plant‑specific installation details.

Reporting to the Plant Discipline Lead, you will be responsible for ensuring all plant design outputs are delivered to the highest standards of quality, accuracy, safety, and compliance. You will work closely with Plant Engineers and multidisciplinary design teams to develop practical, constructable designs that meet technical specifications, operational requirements, and client expectations.

Using your extensive knowledge of substation plant design, you will lead the production and checking of engineering drawings, ensuring the correct application of industry standards, design clearances, equipment interfaces, and site‑specific constraints. You will support the integration of primary plant equipment including transformers, switch gear, reactors, instrument transformers, steel structures, and associated plant systems within complex transmission environments.

We are looking for a highly motivated individual with a strong background in HV substation plant layout and design, excellent CAD and digital engineering skills, and a thorough understanding of transmission network infrastructure. You will bring a proactive approach to problem‑solving, drive technical excellence within the Drawing Office, and support the development of plant design capability through mentoring and knowledge sharing.

At Scottish Power, you will be part of a collaborative engineering environment where innovation, safety, and continuous improvement are at the heart of everything we do. This is an exciting opportunity to play a key role in delivering critical transmission projects while helping to shape and develop best practice in plant design across the business.
