Field Engineer – Industrial Refrigeration Doncaster / England

Join a sustainability-driven industrial refrigeration specialist as a Field Engineer, delivering expert service across the UK and backed by over thirty years of European engineering excellence.

A respected European manufacturer of industrial refrigeration systems is growing its UK service team and seeking an experienced Field Engineer to support its expanding client base.

Built on a foundation of natural refrigerant technology, the business serves clients across food production, logistics and process industries — helping them transition to cleaner, more energy-efficient operations.

All installed systems are supported by a real-time remote monitoring platform that proactively identifies issues before they escalate.

This is a full-time, field-based position with Doncaster as the ideal home base, given the spread of client sites across the UK.

As the primary technical presence in the field, you will be responsible for keeping mission-critical refrigeration systems running safely and at peak performance.

The Role

As a Field Engineer, you will take ownership of the day-to-day technical health of installed systems across a range of customer sites.

Your schedule will include a mix of reactive callouts, planned maintenance visits and commissioning support — all with the backing of a European engineering team and live system data at your fingertips.

What You'll Be Doing

Diagnosing and resolving faults across industrial refrigeration systems, including ammonia plant

Delivering planned preventative maintenance to ensure systems operate safely and efficiently

Responding to breakdown callouts and carrying out on-site repairs to a consistently high standard

Supporting the installation, commissioning and performance testing of new equipment

Collaborating with the remote monitoring team to interpret system data and respond to alerts

Building strong client relationships through clear, professional on-site communication

Maintaining thorough service records, job sheets and compliance documentation

What You'll Need

- At least three years of hands-on experience in industrial machinery manufacturing or refrigeration servicing

- Proven experience working with ammonia refrigeration systems

- A valid ammonia handling certificate — this is a strict requirement for the role

- Strong diagnostic and fault-finding skills across mechanical, electrical and control systems

- The ability to work independently, self-manage your schedule and prioritise effectively

- Confident communication skills for technical client-facing interactions

- A full, valid UK driving licence

- Additional technical qualifications or industry certifications are a plus

Work Permissions

Applicants must have the right to work in the United Kingdom.

Visa sponsorship is not available for this position.

What's on Offer

- A competitive salary based on experience and certifications

- A company vehicle for UK-wide field work

- The opportunity to work with advanced natural refrigerant technology from an established European manufacturer

- Ongoing technical training and development

- Direct access to a highly experienced European engineering team

- Real progression opportunities as the UK operation continues to scale

Why This Role Is Worth Your Attention

Industrial refrigeration is a critical part of the UK's food supply chain, logistics network and process manufacturing sector.

As the industry shifts towards natural refrigerants in response to carbon reduction targets, engineers with ammonia expertise are becoming increasingly hard to find — making this a smart long-term career move.

Working directly for a manufacturer rather than a contractor gives you unrivalled product knowledge, factory-level technical support and a clear path into senior service, commissioning or technical leadership roles in the future.
