The Role

This is a hands-on leadership position, managing a team of six skilled engineers within a specialist milling and secondary processing environment.

You will be equally comfortable:

• Leading, motivating and developing your team

• Managing maintenance strategy, KPIs and performance

• Owning SAP CMMS processes and maintenance planning

• Stepping onto the tools when required to support your engineers

This is a role for someone who thrives on challenge, accountability and variety — where no two days are the same.

Key Responsibilities

• Build a strong safety-first culture and ensure compliance with all HSE and environmental standards

• Deliver planned and reactive maintenance across kiln, milling and associated process plant

• Maximise plant reliability and OEE

• Manage the site maintenance budget and control expenditure

• Oversee site stores and critical spares management

• Drive lean manufacturing principles and continuous improvement initiatives

• Ensure compliance with ISO standards and structured maintenance systems

• Support capital projects, plant upgrades and refurbishment activities

• Collaborate closely with operations, quality, safety and procurement teams

About You

You are a confident engineering manager who leads from the front.

You bring experience from a manufacturing, minerals or milling environment, with strong technical capability and excellent organisational discipline.

You will have:

• Proven experience leading engineering maintenance teams

• Strong mechanical and electrical engineering knowledge

• Experience within heavy industrial or processing environments

• Strong SAP / CMMS knowledge and robust back-office management skills

• Budget and cost control experience

• Understanding of lean manufacturing and continuous improvement methodologies

• Knowledge of ISO standards and structured compliance systems

Most importantly, you build strong relationships. You create trust, set high standards and are willing to step in when needed to support your team.

Why Join Us?

This is an opportunity to take ownership of engineering performance within a specialist industrial site, shape the culture of a capable team and drive meaningful improvement — all within a stable, globally respected organisation.

If you are an ambitious engineering leader ready for a new challenge, we would welcome your application.
