Company Overview
BioteCH4 are one of the leading AD operators in the UK, handling the collection and transportation of food waste, oils and fats recycling.
We own and operate a group of anaerobic digestion facilities across the UK. We also provide biological support, emergency response and feedstock supply to other operators within the industry. Our industry expertise means we not only have the knowledge and experience to deal with all the food waste the UK produces.
Summary
We are seeking an experienced Field Engineering Manager to work in a Group role, working across all of our AD facilities.
The Field Engineering Manager is responsible for leading and coordinating a team of Field Engineers operating across multiple Food Waste AD sites. This role ensures safe, efficient, and reliable engineering performance by organising work across sites, delegating tasks, managing planned and reactive maintenance, and overseeing major works such as CHP servicing and G2G plant servicing and upgrades. The position acts as the central point of leadership for Field Engineers, ensuring consistent engineering standards, resourcing, and execution. This role works closely with the Site Engineering Manager to cohesively coordinate between site and larger project works at sites.
Each AD site will be manned with on call engineering call out rota – the Site Engineering Manager will be expected to be the Senior for the on call rota for escalation from this team which will be typically 1 in 3.
