* Work safely in a live electrical testing environment, either independently or as part of a team.
* Support continuous improvement by identifying root causes of faults and helping implement corrective actions.
* Collaborate with engineering and quality teams to enhance product performance and reliability.
* Ensure all testing activities comply with relevant electrical regulations and safety standards.


What this role suits you

* Strong hands‑on experience in testing diesel generators and electrical systems.
* Confident working with 3‑phase AC generators, control panels and synchronisation systems.
* Excellent fault‑finding skills across both electrical and mechanical systems.
* Comfortable working in a fast‑paced, high‑responsibility live test environment.
