That's why we actively encourage women engineers to apply and thrive in our inclusive, safety-first environment.
About the Role
Join our expert operations team and play a pivotal role in ensuring the safe, efficient, and reliable operations of our gas reciprocating engines and associated plant equipment. You will play a key role in identifying early signs of faults, conducting diagnostics, and carrying out both reactive and planned maintenance to minimise engine downtime across our range of site-based power generation plants. This ensures our fleet operates at peak performance, supporting the continuous delivery of flexible power generation.
Working in a collaborative, safety-first environment, you'll contribute to operational excellence and innovation. Ideally, you'll bring experience in power generation or industrial maintenance—particularly with gas reciprocating engines—and demonstrate strong fault-finding skills and a proactive approach.
