The Role
Are you ready to take on a hands-on role where no two days are the same? As an Instrumentation Field Service Engineer, you’ll play a key part in keeping our assets running smoothly by delivering expert maintenance and technical support to our Production team.
Working in a fast-paced, modern maintenance environment, you’ll be at the forefront of proactive, planned, and reactive support—making a real impact every day. Your expertise will help ensure we stay compliant with all company, statutory, and regulatory standards, all while helping to protect the environment.
But that’s not all—you’ll also have the chance to shape the future of our operations by contributing to capital and operational projects, ensuring our assets are built with maintenance and performance in mind from day one.
This role offers a great mix of independence and teamwork. You’ll need to be comfortable working solo at times, but you’ll also collaborate closely with a supportive team when needed.
Please note:
- This role involves working in confined spaces.
- You’ll also take part in an out-of-hours standby rota, so flexibility is key.

- Championing safety by ensuring full compliance with Health & Safety regulations and internal policies.
- Keeping a close eye on the numbers by managing budgets effectively and maintaining financial control.
- Providing accurate, reliable asset performance and repair data to feed into our corporate systems—your insights will help drive smarter decisions.
- Tackling recurring maintenance issues head-on by analysing root causes and recommending long-term solutions.
