The Position: Senior Electrical Engineer

We are seeking an Electrical Engineer or Senior Electrical Engineer to join our growing engineering and design consultancy team. This role offers the opportunity to deliver high-quality electrical design across a diverse portfolio of industrial and energy projects, working closely within a multidisciplinary environment and maintaining strong engagement with clients, contractors, and vendors.

You will play a key part in delivering high-quality electrical design work, contribute to project decisions, mentor junior engineers where appropriate, and take ownership of high-quality deliverables from concept through to detailed design.

Some of the main responsibilities of the Senior Electrical Engineer will include:

Produce, review and support the approval of electrical engineering documents including calculations, specifications, datasheets, schedules, drawings and technical reports.
Carry out and review electrical design activities such as cable sizing (ElectricalOM or similar), load assessments and equipment selection, ensuring designs meet functional, safety and performance requirements.
Support the preparation, review and coordination of drawings including general arrangements, layouts, single line diagrams, block diagrams and schematics.
Provide input to project schedules, deliverable lists, cost estimates and the identification of scope, engineering deliverables and resource requirements for allocated tasks.
Support change management by identifying variations in scope and communicating impacts to the Project Manager.

Liaise with clients, contractors, vendors and internal teams to clarify design requirements, resolve technical queries and support alignment across the project.

Participate in design reviews, project meetings and technical workshops, working closely with other engineering disciplines to deliver integrated project solutions.

Provide guidance to junior engineers and apprentices where appropriate, contributing to a positive team culture focused on engineering excellence.

This role offers the opportunity to work on varied, technically challenging projects within a collaborative, multidisciplinary team. You'll be part of a growing consultancy where your contribution has real visibility and impact, with strong professional development and Chartership support to help you progress toward Senior or Principal levels. If you’re an Electrical Engineer ready to take the next step—or a Senior Electrical Engineer seeking broader technical influence and more diverse project exposure—we would love to hear from you.

Preferred Profile:

Degree in Electrical Engineering or equivalent relevant industry experience (HNC/HND or similar also considered), with a desire to pursue Chartered status advantageous.

Strong experience in detailed electrical design within industrial, infrastructure or energy sectors, with good working knowledge of the 18th Edition Wiring Regulations (BS 7671).

Competency with cable sizing tools such as ElectricalOM, Amtech or similar, and familiarity with general engineering software and MS Office.

Experience contributing to multidisciplinary project environments and engaging confidently with clients, vendors and colleagues.

Awareness or experience of HV systems (up to 11/33 kV), ATEX/hazardous area classification or earthing and lightning protection design is desirable.

Experience using ETAP or similar software for load flow, fault levels or protection studies is beneficial.

Lighting design experience and previous experience mentoring junior staff would be advantageous.
