Electrical Design Engineer (HV/LV) - Energy Infrastructure & Solar PV

About the role
We need everyone's positive energy and innovative thinking to lead the transition to Net Zero. That's why we welcome applications from all backgrounds and experiences, and we offer a range of flexible working options to suit everyone.

Location: Home-based with regular UK travel

Here's what you'll be doing

Our Energy Infrastructure Solutions business designs, builds and operates energy systems for industrial and commercial customers. We deliver a range of technologies including LV/HV distribution, Solar PV, CHP, and energy storage solutions. By combining different technologies, we maximise efficiency, resilience, and support our customers in achieving Net Zero.

Due to rapid growth, we have an exciting opportunity for a multi-skilled Electrical Design Engineer to join our B2B Solutions team. You'll take ownership of the electrical design function across the full lifecycle of projects - from concept and feasibility through detailed design, specification, and commissioning. While solar PV experience would be highly desirable, your expertise in LV/HV electrical systems is the key focus of this role.

Working with Sales, Development Engineers, Supply Chain, Project Management and Installation teams, you'll deliver high-quality electrical designs that integrate seamlessly into large-scale commercial and industrial energy solutions.

Key responsibilities include

• Leading electrical designs including LV and HV schematics, single-line diagrams, protection & coordination studies, panel schedules and connection diagrams.
• Producing spatially coordinated layouts, 3D modelling and AutoCAD drawings.
• Performing load flow, fault level and discrimination studies to ensure safe and compliant design.
• Supporting grid connection and DNO applications (including G99 submissions).
• Reviewing and approving designs, recommending technical improvements to optimise efficiency, quality and performance.
• Selecting electrical components and equipment in line with project requirements,
• Providing technical support to Sales, Project Delivery and Installation teams.
• Ensuring compliance with legislation, standards, HSSE requirements, and CDM responsibilities.
• Where applicable, carrying out design integration for Solar PV systems, storage, and CHP solutions.

What we need from you

• Proven experience in electrical design engineering, ideally across both LV and HV systems.
• Familiarity with electrical infrastructure projects in industrial or commercial environments.
• Experience with AutoCAD, electrical design software, and simulation tools.
• Knowledge of relevant standards, legislation and health, safety & environmental compliance.
• Strong organisational and workload management skills with excellent attention to detail.
• Full UK/EU driving licence.

It would be great if you had

• Experience designing and integrating Solar PV systems (rooftop or ground-mounted).
• Familiarity with PV modelling software such as PV SOL or PVSyst.
• Knowledge of PV manufacturers, components, and associated LV/HV works.
• An engineering qualification (Degree/HNC or equivalent).
• A strong understanding of the commercial impact of design and engineering decisions.
