Description

Bring your energy to Aggreko as a BESS Technician based in our Operations Team in our Widnes depot. As a BESS Technician, you are responsible for ensuring all fleet is made ready for hire, through turnarounds, repairs and maintenance. This includes any upgrades, retrofits and modifications to support customer requirements.

Power without pause. Heating, cooling and oil-free air without end. We keep our customers’ worlds on. From world-class events that last a few weeks to mining operations and remote communities who rely on us for decades.

What you’ll do as a BESS Technician:

  • Upon the return of any fleet asset, carry out a post-contract assessment to determine the level of work required and ensure the asset is assigned the correct status

  • Inspect, diagnose, and resolve faults, carrying out modifications or customisations to equipment in line with customer specifications where required

  • Perform maintenance and repair activities in accordance with company procedures and, where necessary, in consultation with approved suppliers

  • Provide technical and operational support to the wider business, with a particular focus on Battery Energy Storage Systems (BESS), both remotely and on-site when required

  • Ensure all service appointments, records, and documentation are maintained accurately and up to date, including the completion of Field Service Logs (FSL) and ATA reports for each asset

You are:

  • Experience working with Battery Energy Storage Systems (BESS), including fleet maintenance, fault finding, and electrical repairs

  • A recognised technical qualification, such as City & Guilds, ONC Level 3, or equivalent in a relevant discipline

  • Strong technical aptitude with the ability and enthusiasm to learn about a broad range of products, technologies, and applications

  • Excellent communication and relationship-building skills, with the ability to work effectively with internal and external stakeholders at all levels

  • A strong commitment to health and safety, ensuring compliance with regulations and promoting safe working practices at all times

  • Good IT skills, including proficiency in Microsoft Office applications, alongside a flexible approach and willingness to travel when required

Here’s what you’ll get:

  • A highly competitive salary and comprehensive benefits package, including a generous pension plan, annual bonus opportunities, and Life Assurance.

  • Annual leave allowance of 30 days plus 3 public holidays, with the flexibility to buy or sell additional days to suit your lifestyle

  • Ongoing training and personalised development pathways to help you grow your skills and progress in your career

  • Paid volunteering days, giving you the chance to make a positive impact in your local community

  • Access to our Employee Assistance Programme, offering confidential support and resources to promote your wellbeing and a healthy work–life balance

Our people are can-do, positive, resilient and persistent. If that feels like you, apply now and build your career with the people bringing energy to the world.
