Greenstar operates 40+ recycling and waste-management sites across Ireland with 520+ employees, now mid-migration onto a new ERP system while building out CMMS, hazard-risk management, and contractor-control systems. The hiring velocity is accelerating—55 roles posted in the last 30 days—with operational roles (43 open) far outpacing engineering (11), suggesting the bottleneck is execution capacity in field operations and compliance rather than product development.
