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 Site Engineering Manager to work in a Group role, working across all of our AD facilities.
The Site Engineering Manager is responsible for leading and coordinating engineering teams across the Food Waste AD sites. This role ensures that all plants operate safely, reliably, and efficiently by managing maintenance strategies, overseeing engineering performance, prioritising work across sites, and driving continuous improvement. The manager acts as the central point of technical leadership for site engineers and ensures engineering standards, compliance, and asset integrity are consistently maintained. This role works closely with the Field 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.
