About the Role
The role will work on the HS2 project, the UK’s new high speed rail network designed to drive economic growth by connecting 8 of the UK’s 10 biggest cities with fast, reliable, and frequent services. Costain is delivering the HS2 Rail Systems Tunnel and Lineside Mechanical and Electrical Systems works across the entire HS2 Route (HRS02). The scope includes the design, supply, manufacture, installation, testing, commissioning, and maintenance (until handover) of tunnel and lineside M&E systems, including tunnel services within shafts, tunnels, and cross-passages, as well as low voltage electrical power distribution along the open route. Additionally, Costain will design, supply, install, test, and commission tunnel ventilation systems. The project value at award is £500m.

The Electrical Engineer will support the design, review, and implementation of electrical systems for the HRS02 HS2 open route lineside works, interfacing and coordinating with other HS2 Rail Systems contractors such as track, signalling, telecoms, OHLE, and HV power. Responsibilities include reviewing technical documentation, drawings, and specifications; undertaking material selection and preparing technical approval and acceptance documentation; ensuring compliance with relevant UK rail industry standards and HS2 Works Information; producing quality documentation such as ITPS and installation verification check sheets; identifying and managing technical risks; supporting assurance, quality, and safety processes; and providing engineering support during installation, testing, and commissioning activities.

The role requires close collaboration with the Engineering team to coordinate requirements and programme delivery, liaising with procurement to specify and source electrical equipment, and maintaining coordination with Design, Safety, and Planning teams. The successful candidate will also promote and support the implementation of Costain values and behaviours across the project.
