At Clarke Energy, our Electrical Design Engineers play a vital role in shaping the energy systems that power hospitals, industry and communities across the UK and beyond. From early concept through to installation and commissioning, you’ll be closely involved in designing reliable, low‑carbon power generation solutions that genuinely make a difference.

This role is ideal for an engineer who enjoys solving real‑world problems, collaborating across disciplines and seeing their designs come to life on site. You’ll work within a supportive, knowledgeable engineering team where quality, safety and continuous improvement are taken seriously – but people always come first.

Designing resilient, real‑world power systems: you’ll take conceptual electrical designs and develop them into fully engineered solutions that meet contractual, technical and regulatory requirements.

This will include producing specifications, calculations, equipment selection and detailed design documentation for a wide range of technologies including gas‑powered generation, CHP, battery energy storage systems (BESS), hydrogen, solar, wind and microgrids.

Carry out power system studies such as load flows, fault analysis, protection studies, harmonic assessments (G5/5), voltage flicker (P28) and G99 simulations – ensuring our designs are robust, compliant and fit for purpose.

Supporting projects from start to finish: your input will be valued right from the sales stage, where you’ll support tender designs and technical submissions, through to installation, commissioning and testing.

You’ll work closely with Project Managers, providing timely technical documentation and practical engineering support when it matters most.

Seeing your designs transition from drawings to installed systems is a key part of this role.

Collaborating across disciplines: you’ll work hand‑in‑hand with Mechanical Design Engineers, CAD technicians and wider project teams to develop integrated design solutions.

You’ll coordinate design activity, contribute to HAZOPs and risk assessments, and help ensure that design outputs are delivered to agreed…
