Bring your energy to Aggreko as a BESS Technician based in Dumbarton. As a BESS Technician you are responsible for the repairs and maintenance of the BESS fleet that is offered to S&R to make it ready for hire again within the requirements and standards.

What you’ll do as a BESS Technician:

• Upon arrival of the fleet, prepare an estimate, determine which parts are needed and draw up an action plan.
• Carry out maintenance and repair work in accordance with company guidelines and/or in consultation with suppliers.

• Provide support for the operational business specifically focused on BESS
• Keeping track of timesheets, maintenance and work reports

You are:

• Time‑served Electrical Engineer (SCQF Level 7 / SVQ Level 3 or apprenticeship) with demonstrable hands‑on experience in single‑ and three‑phase electrics, and strong practical knowledge of AC and DC control systems.
• Proven experience maintaining and repairing BESS fleets (Battery Energy Storage Systems) and associated electrical equipment — skilled at fault diagnosis, testing and delivering robust repairs.
• Must hold a full, clean and valid driving license
• Technically curious and quick to learn: comfortable reading schematics, understanding new products and applications, and applying technical knowledge across diverse systems.
• Excellent interpersonal skills with clear, professional communication; adept at building relationships and engaging stakeholders at all levels (internal and external) to achieve safe, timely outcomes.
• Safety‑first mindset with up‑to‑date working practices and regulatory compliance; competent in MS Office and PC tools, flexible and willing to travel as required.

Here’s what you’ll get:
