Mechanical Field Service Engineer

As a Mechanical Field Service Engineer, you’ll deliver expert maintenance and technical support to ensure mechanical systems and powered assets operate safely, efficiently, and reliably. Your work plays a vital role in supporting high-quality water and wastewater services, with a strong emphasis on renewable energy generation through anaerobic digestion.

This is a hands-on, multi-skilled role that demands flexibility, the ability to work independently, and readiness to operate in confined spaces. You’ll also contribute to both capital and operational projects, ensuring mechanical assets are designed, installed, and maintained to meet performance and reliability standards. Participation in an out-of-hours standby rota is part of the role.

A note about skills and development

You’ll join us as an Mechanical Engineer (single skill) from day one. But don’t worry—if your goal is to develop into a flexi-skilled engineer, we’ll fully support you.
