• Familiarity with both dry-cast (pipe, box culvert, utility products) and wet-cast (architectural, structural) production methods a plus
• Strong documentation and record-keeping skills
• Ability to read blueprints, mix designs, and project specifications
• Physical ability to work in a plant environment, including exposure to dust, noise, and varying temperatures
• Basic computer proficiency (Excel, QC software/ERP systems)

Preferred Experience

• Experience supporting NPCA Plant Certification renewals or audits
• Background in DOT or state-specification precast products (culverts, manholes, vaults)
• Bilingual (English/Spanish) a plus in many plant environments
