Job Description

Field Service Engineer - Power Generation

About us

Infinis is the UK's leading renewable energy generator of low-carbon power from captured methane. We convert methane gas from landfill sites and disused mines into electricity. Our sustainable energy expertise also extends to solar farms and battery energy storage (BESS) technology.

This work helps reduce greenhouse gas emissions on climate change and provides secure, efficient local power generation. Infinis is supporting the energy transition to net zero. We are committed to innovation, environmental responsibility, and providing safe and efficient local energy solutions.

If you're passionate about

engineering, sustainability, and power generation,

this is your opportunity to thrive in a forward-thinking company. With the demand for renewables set to rise, the energy industry is a great place to build your career.

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.
