If you''re an electrically or mechanically qualified engineer with experience working on diesel generators, this is an opportunity to join a business where you''ll be trusted to work independently, get out on the road, and develop your skills across a wide range of generator equipment.

Why consider this role?

This isn''t a workshop-based role where you''ll be doing the same job every day.

You''ll be travelling to customer sites across the North West & Midlands, servicing and repairing generating sets, carrying out load bank testing and helping customers keep their power systems running when they need them most.

With strong overtime rates, a remote working setup, training opportunities and genuine career development, this is an excellent opportunity for an experienced Generator Engineer looking for their next move.

The Role

As a Generator Service Engineer, you''ll be responsible for the servicing, inspection, testing and repair of diesel generating sets across customer sites and the company''s own hire fleet.

Your responsibilities will include:

  • Carrying out planned servicing and maintenance of diesel generators.
  • Attending customer sites across the UK to diagnose and repair faults.
  • Carrying out fault finding, testing and diagnostics.
  • Performing load bank testing to ensure generators are operating efficiently.
  • Completing pre- and post-hire inspections.
  • Servicing and maintaining the company''s own generator hire fleet.
  • Carrying out temporary repairs where required to keep customers operational while parts are sourced.
  • Supporting generator installations and fabrication work when required.
  • Assisting with UPS battery build and installation projects.
  • Maintaining accurate records and ensuring equipment is safe, clean and ready for use.
  • Building strong relationships with customers and providing a professional service at every visit.
  • Participating in a 24/7 call-out rota.

What we''re looking for

We''re interested in speaking with engineers who have a strong mechanical or electrical background and ideally have experience working specifically with diesel generators.

Essential:

  • Minimum 2 years'' experience working with diesel generators.
  • Mechanical or Electrical engineering qualification.
  • City & Guilds / NVQ in Engineering or equivalent.
  • Strong fault-finding and diagnostic ability.
  • Ability to carry out temporary repairs to keep equipment operational.
  • Comfortable working independently and as part of a team.
  • Full UK driving licence.
  • Willingness to occasionally work away from home.
  • Flexibility to participate in a 24/7 call-out rota.

Desirable:

  • Experience working on a variety of generator manufacturers.
  • Manufacturer-specific generator training.
  • Experience with generator installation or fabrication.
  • UPS/battery installation experience.

What''s in it for you?

  • -35,000 - -42,000 salary, depending on experience.
  • Excellent overtime earning potential.
  • Overtime paid at 1.5x.
  • Saturday PM & Sunday paid at 2x.
  • Remote-based working with support from the Preston depot.
  • Monday-Thursday 8:00am-5:00pm.
  • Friday 8:00am-3:00pm.
  • 25 days annual leave + bank holidays.
  • Optional company pension scheme.
