About the Role

Are you ready to work on a major UK infrastructure project that offers career development, long‑term stability and hands‑on challenge? With 15 years remaining on this iconic programme, you can play a vital role in maintaining one of the UK’s most important transport networks.

As an Electrical Maintenance Technician, based at Dartford, Kent, you’ll be at the heart of keeping the Dartford River Crossing and M25 tunnels safe, operational and resilient.

This role provides a unique opportunity to gain specialist skills, continuous professional development and meaningful career progression while contributing to the safe operation of Europe’s busiest motorway.

In this role, you’ll be responsible for the safe and efficient inspection, maintenance and operation of electrical systems across the M25 tunnels and Dartford River Crossing. Your work will involve a blend of planned maintenance, responsive repairs and fault diagnosis—ensuring every day brings new opportunities to develop your expertise.

You will maintain and repair essential electrical equipment including:

• Switchgear

Using your technical knowledge and problem‑solving skills, you will diagnose faults, interpret drawings and carry out repairs independently to minimise downtime and maximise network performance. You will also undertake civil, electrical and mechanical maintenance tasks to support overall asset resilience.

Safety is paramount. You will follow strict health and safety procedures, maintain vehicles, plant and equipment, and respond to emergency incidents—ensuring hazards are managed quickly and operations are restored safely.

You’ll work as part of a skilled and supportive team, contributing to a culture of safety, collaboration and continuous improvement. You will also support the wider commitment to Zero Harm and ongoing professional development within the team.
