Senior Electrical Design Engineer

Team Overview:

The Design department is responsible for developing innovative, practical, and fully coordinated mechanical and electrical building services solutions tailored to each project. Working closely with clients, project teams, and the BIM department, the design team transforms concepts into detailed, build-ready technical designs that meet regulatory standards, client specifications, and sustainability goals. Their work underpins the technical accuracy and efficiency of our installations, ensuring seamless integration from planning through to construction.

Role Overview:

As an Electrical Design Engineer, you will help deliver the low-carbon energy infrastructure that supports Alternative Heat’s commitment to decarbonisation. You will develop coordinated electrical designs for projects across healthcare, education, leisure and residential sectors, including LV distribution, load assessments, circuit design, plant power supplies, general and emergency lighting, metering, generators, transformers, and electrical interfaces with mechanical plant and BMS packages. Working with the electrical, mechanical and BIM teams, you will produce calculations, schematics, schedules, and coordinated layouts from design development through construction and handover. Your work will contribute to safe, buildable, and energy-efficient systems that reduce carbon emissions and support our clients’ decarbonisation objectives.

Responsibilities

• Prepare load assessments and design calculations, including cable sizing, voltage drop, fault current, protective device selection, and discrimination, using ElectricalOM.
• Carry out site surveys to assess existing electrical infrastructure, incoming supplies, distribution equipment, connected loads, containment routes and project constraints.
• Lead the electrical design delivery of assigned projects from concept through to construction, commissioning and as-built handover, coordinating design activities, priorities and deliverables in line with the project programme.
• Produce LV single-line diagrams, panel and distribution board schedules, schematics, equipment schedules and layouts for plant power, isolators, general power, lighting, emergency lighting, metering, containment and cable routes.
• Select and specify electrical systems and equipment, including LV switchgear, distribution boards, transformers, generators, protective devices, cables and metering.
• Coordinate with mechanical, controls, civil, structural and BIM teams to resolve equipment locations, builder's work requirements, service routes, access and maintenance clearances.
• Define and coordinate electrical interfaces with mechanical plant and BMS packages, including power supplies, control wiring, signals, alarms, interlocks and metering requirements.
• Review project requirements, legislation and standards; manage electrical design risks and interfaces; and prepare design reports, risk assessments, technical submissions, RFIs and responses to technical queries.
• Lead and attend client, consultant and internal design meetings, presenting design proposals, resolving technical matters, agreeing actions and ensuring decisions are incorporated into the coordinated design.
• Coordinate with suppliers, project managers and site teams through procurement, construction, testing and commissioning, incorporating agreed changes into as-built information.
• Review and check calculations, drawings, schedules and technical submissions, ensuring compliance with project requirements, applicable standards and departmental QA procedures.
• Provide technical guidance and support the consistent application of design standards, procedures and lessons learned across projects.
• Travel to company and project sites throughout the UK and Ireland will occasionally be required.
• The above list is not exhaustive, and additional tasks may be required as directed.
