Our client is a specialist engineering company across clean and wastewater infrastructure projects throughout the UK. Working closely with tier-one contractors and framework partners, they deliver robust, buildable electrical designs across treatment works, pumping stations, and network assets.

Due to continued growth, they are seeking a mid-to-senior Electrical Design Engineer to join their South East-based team.

The Role

You will be involved in the full D&B design lifecycle, producing practical, construction-ready electrical designs and supporting projects through delivery.

Key responsibilities include:

Electrical design from outline design through to detailed design and construction issue

Development of buildable LV electrical designs including power distribution, MCCs, switch gear, control panels, standby generation, and earthing/bonding

Preparation of electrical calculations such as load schedules, cable sizing, fault levels, and protection coordination

Production and coordination of electrical drawings including single line diagrams, schematics, layouts, and cable schedules

Close coordination with mechanical, civil, ICA, and construction teams to resolve buildability, sequencing, and installation challenges

Technical review of supplier and subcontractor design information

Support during construction, commissioning, and handover phases

Ensuring compliance with BS 7671, WIMES, DSEAR, CDM, and client standards

About You

You will ideally have:

A qualification in Electrical Engineering (degree, HNC/HND, or equivalent)

Proven experience delivering electrical design within D&B water or wastewater projects

Strong understanding of construction-stage design development and contractor interfaces

Experience working with MCC suppliers and electrical subcontractors

Familiarity with electrical design tools such as Amtech/Trimble and AutoCAD

A pragmatic, delivery-focused approach to engineering design

Clear communication skills and confidence working in fast-paced project environments

Working towards or holding Chartered Engineer status (IET or equivalent) would be beneficial but is not essential.

This role will suit an Electrical Design Engineer who enjoys hands-on design, contractor collaboration, and seeing projects through to delivery.
