Location: Home based with project related travel across the UK

Hours: Full time, 40 hours per week

At Mitie, our people are our greatest strength, and our promise is to create a place to work where you can thrive and be your best every day. We're looking for an experienced Primary Design Engineer to support the delivery of high-voltage renewable projects by producing high-quality primary electrical designs that meet stringent technical, safety and regulatory standards.

This role will see the successful post holder operate from a home location and then travel according to the projects requirements. You will not be travelling extensively every week but we would like to occasionally see you in the office should you be in the vicinity when on client locations.

To give you an idea of some of the locations, the sites can range from Cornwall, Birmingham, Chesterfield, Scunthorpe, Buckinghamshire, Leeds and Glasgow.

Role Responsibilities:

• Produce primary electrical designs for substations, including AIS and GIS layouts up to 132kV , cable routes, LV layouts, switch rooms, control rooms and earthing systems
• Ensure all designs comply with relevant British and international standards, DNO requirements, customer specifications and contractual obligations
• Design and analyse earthing systems for substations, renewables and grid connection projects, including EPR studies, touch and step voltage assessments and soil resistivity testing
• Prepare technical documentation including drawings, calculations, reports, major plant specifications and lightning protection assessments
• Manage and coordinate external design suppliers and collaborate with structural, planning and CAD teams to deliver integrated design solutions

Required Qualifications:

• Degree, HND or HNC in Electrical Engineering (power systems preferred)
• Proven experience in primary electrical design for HV/EHV AC substations (11kV–132kV) and balance of plant projects
• Strong knowledge of industry standards such as BS7671, ENATS, NGTS, BS EN 61936-1 and BS7354
• Experience working within consultancy, contractor or utility environments

What we're looking for:

• A technically strong and detail-oriented primary design engineer
• Ability to manage complex technical interfaces across multiple engineering disciplines
• Strong understanding of substation layouts, earthing design and cable installation practices
• Excellent written and verbal communication skills
• A proactive and organised approach, with the ability to manage multiple project priorities

What's in it for you?

• Opportunity to work on major renewable energy and grid infrastructure projects
• Career development within a specialist high-voltage engineering team
• Hybrid working with flexibility and exposure to projects across the UK
• The Senior SLT can help promote new career opportunities, should you not wish to stay as a PDE over time. For example, if you are looking for routes into the Power Systems team then this will be supported for the right individual.
