About Our Opportunity

We are looking for a Process Engineering Technician to join our Dry Processing team, supporting multiple operations across Cornwall.

This is a varied and hands-on role for someone who enjoys solving problems, analysing data and identifying opportunities to improve processes.

Working closely with operators, engineers and production teams, you'll help optimise plant performance, reduce energy consumption, support new product introductions and deliver improvements that positively impact safety, quality, efficiency and cost.

No two days will be the same. One week you may be supporting a new product trial, the next analysing process data to improve drying performance, investigating production challenges or working with operational teams to implement improvements that make a measurable difference.

What You'll Be Doing

Process Performance & Improvement

• Monitoring plant performance and identifying opportunities to improve efficiency.
• Supporting Operational Excellence and Continuous Improvement projects.
• Helping optimise drying processes, product quality and production performance.
• Using process data to identify trends, investigate issues and recommend solutions.
• Supporting improvements that reduce energy consumption and improve operational efficiency.

Trials & Technical Development

• Supporting root cause analysis activities.
• Working with site teams to identify, test and implement solutions.
• Helping operators overcome process-related challenges through practical improvements.

Health, Safety & Compliance

• Promoting a strong safety culture and supporting Imerys' commitment to Zero Harm.
• Working in accordance with all Health, Safety and Environmental policies and procedures.
• Carrying out activities in line with Risk Assessments, Safe Systems of Work and site standards.
• Supporting investigations into process and operational issues where safety performance could be impacted.
• Identifying opportunities to improve both process efficiency and operational safety.
• Ensuring process improvements are developed and implemented with safety at the forefront.
• Maintaining accurate records, reports and improvement documentation in line with company requirements.

Stakeholder Collaboration

• Building strong relationships with production and operational teams.
• Supporting implementation of new processes and ways of working.
• Communicating technical information clearly and confidently.
• Working collaboratively across engineering, operations and quality functions.

What Good Looks Like

You enjoy understanding how processes work and are naturally curious about how they can be improved.

You are comfortable using data to support decisions and have the confidence to challenge existing ways of working when opportunities for improvement exist.

You take ownership of your work and enjoy seeing projects through from initial idea to final implementation.

Most importantly, you enjoy working with people and building positive relationships to help drive change successfully.

What You'll Bring
