Ready to take the next step in your leadership career?

You will:
- Manage the day-to-day operation of the ReadyMix plant including contractor activities
- Promote and drive a positive safety culture across site
- Manage daily production operations, stock levels and operational costs
- Ensure efficient concrete production to required quality standards
- Monitor and improve plant performance through KPIs
- Resolve operational and customer queries in a timely manner
- Maintain excellent housekeeping and site standards
- Batch concrete to customer specifications whilst meeting internal quality requirements
- Manage both fixed and variable site costs in line with budget expectations
- Identify and implement continuous improvement opportunities
What We’re Looking For
- Supervisory or management experience within a manufacturing, production, industrial or heavy industry environment
- Strong understanding of Health, Safety and Environmental standards
- Experience working with Risk Assessments and Safe Systems of Work
- Excellent communication and people management skills
- Strong organisational and problem-solving abilities
- Ability to manage competing priorities in a fast-paced environment
- Proactive approach to performance improvement and customer service
- Proven ability to thrive in a fast-paced operational setting
- Continuous improvement mindset with focus on processes, performance and standards
- Experience in ReadyMix, aggregates, construction materials (preferred)
- IOSH Managing Safely qualification (advantageous)
- NVQ in fixed or mobile plant operations (advantageous)
