The Opportunity - Generator Test engineer
About the role:
The Generator Test Engineer role is a hands-on, technically demanding position focused on the testing, validation and continuous improvement of generator systems and associated technologies. You will be responsible for ensuring that diesel generators, hydrogen generators and lithium iron battery packs meet both industry standards and customer specifications.
Working in a fast-paced, live electrical test environment, you will play a key role in verifying product performance, identifying faults and contributing to quality improvements. This role involves close collaboration with engineering and quality teams to ensure products are reliable, safe, and fit for purpose for end users.
What does this role involve day to day?
• Conducting electrical and mechanical testing of diesel generators (70kVA–625kVA), hydrogen generators and battery systems
• Carrying out generator synchronisation using Deep Sea and DEIF controllers
• Performing advanced fault finding across AC/DC circuits, control panels, wiring harnesses and mechanical systems (fuel, coolant, oil, AdBlue)
• Testing LV electrical systems and verifying performance against specifications and standards
• Reading and interpreting electrical schematics and engineering drawings
• Recording test results, updating build documents and ensuring all work follows standard operating procedures (SOPs)
• Working safely in a live electrical testing environment, either independently or as part of a team
• Supporting continuous improvement by identifying root causes of faults and helping implement corrective actions
• Collaborating with engineering and quality teams to enhance product performance and reliability
• Ensuring all testing activities comply with relevant electrical regulations and safety standards
This will be suited to you if
• You have strong hands-on experience in testing diesel generators and electrical systems
• You are confident working with 3-phase AC generators, control panels and synchronisation systems
• You have excellent fault-finding skills across both electrical and mechanical systems
• You are comfortable working in a fast-paced, high-responsibility live test environment
• You can work both independently and collaboratively within a small team
• You are highly organised and able to follow structured processes while maintaining accurate records
• You can interpret technical drawings and schematics with ease
• You are proactive in identifying issues and contributing to product improvements
• You have a solid understanding of industry standards and electrical regulations (e.g. 18th Edition, inspection and testing)
Minimum Requirements
• ONC/HNC or higher in Electrical or Electronic based engineering or City and Guilds NVQ Level 3 Qualification in Electrical Installation or Maintenance.
• City and Guilds 2391 Inspection and Testing or EAL Equivalent (BS7671) 18TH Edition 2382 Electrical Regulations. Recognised Electrical Engineering Apprenticeship Training. Experience using Deepsea / DEIF or Comap control units is a must.
• Knowledge of PLC/SCADA/ MODBUS / CANBUS programming & configuration requirements preferred.
