General Manager | Tunnel Tech South
Shape the future of a world-leading substrate operation
Monaghan Mushrooms is at the forefront of mushroom production, innovation, and sustainability. At the heart of this success is our advanced substrate manufacturing capability, and our Tunnel Tech South site represents one of the most sophisticated substrate operations in the UK.
Following more than £10m of investment over the past decade, Tunnel Tech South is a state-of-the-art facility located on the John Lewis Leckford Estate. It produces over 1,000 tonnes of high-quality substrate every week, supplying both Monaghan growers and select third-party partners.
We are now seeking a General Manager to lead this flagship operation and drive its next chapter of performance, capability, and growth.
This is not just another operations role. It's a chance to:
Lead a mission-critical site - oversee a seven-day, high-intensity production environment with 24-hour monitoring, ensuring the consistent delivery of a world-class product. Build and inspire high-performing teams - lead c.20 colleagues, including three key managers across each phase of substrate production, developing capability, engagement, and accountability. Drive continuous improvement - elevate productivity, quality, and reliability through cultural leadership, data-driven decision making, and operational excellence. Own the full production ecosystem - from raw material management and supplier relationships to environmental compliance, maintenance oversight, and long-term strategic planning. Protect the environment and our community - uphold the highest standards across Health & Safety, environmental permits, and community relations.
We're looking for a proven operations leader with:
* Significant experience running a complex production, farming, agri-food, composting, or recycling facility. * A hands-on, performance-driven leadership style with the ability to motivate multilingual teams. * Strong commercial acumen and comfort managing budgets, forecasts, and key operational KPIs. * A track record of delivering continuous improvement and operational upgrades. * Excellent communication skills and the confidence to influence across supply chain, procurement, and senior leadership. * Ideally, an agricultural background or related degree (helpful but not essential).
What you'll lead:
* Weekly production of 1,000+ tonnes of substrate, aligned to Group schedules and customer demand. * End-to-end site management: H&S, environmental performance, maintenance, security, quality, and staffing. * Accurate forecasting, supply chain coordination, and raw material optimisation. * A culture rooted in safety, high standards, accountability, and improvement. * Long-term strategic planning to ensure reliability, efficiency, and future-fit capability.
The opportunity
You'll be joining a business with deep agricultural heritage, global scale, and a relentless focus on excellence. Tunnel Tech South is central to that success, and for the right individual, the visibility, impact, and long-term career opportunity are exceptional.
This is your chance to shape the future of one of the UK's most advanced substrate operations, a site with scale, investment, and ambition.
