• Build and maintain strong relationships with quarry, aggregates and construction clients as the main point of contact for workshop‑based repairs and overhauls.
• Drive visibility of workshop performance – utilisation, efficiency, recovery rate, WIP, lead times, first‑time‑fix and rework/returns – and deliver tangible improvements.
• Work closely with Finance and Maintenance to create clear cost/profit baselines and move the workshop towards full profit‑centre operation.
• Standardise and improve processes around quoting, approvals, repair standards, documentation and sign‑off to protect margin and improve customer experience.
• Support, coach and challenge the workshop team day‑to‑day, helping to raise standards and recruit new engineers into the department where required.
• Promote and fully engage with all aspects of safe working practices in the workshop and on customer sites.

• Proven experience managing a workshop or service operation delivering external repairs to customers.
• Track record of growing revenue and developing new business while maintaining safety, quality and on‑time delivery.
• Strong customer‑facing and commercial skills – confident scoping work, preparing quotes, managing variations and discussing options with quarry managers and senior stakeholders.
• Good IT skills, including experience with maintenance/quoting systems and MS Office for job control and KPI reporting.
• A collaborative approach, able to work closely with workshop, maintenance, operations and finance while driving your own objectives.

Benefits

• Permanent role with an established and respectable employer, financially stable business in the heavy mobile plant sector.
• Salary in the region of £60,000‑£65,000 plus company vehicle and benefits.
