Quality Assurance Specialist

We are seeking a detail-oriented Quality Control Specialist to join our precast concrete manufacturing team. This role is responsible for ensuring all precast products — including pipe, box culverts, vaults, structural components, and/or architectural panels — meet applicable industry standards, project specifications, and internal quality benchmarks throughout the production process, from raw material intake through final shipment.

• Perform daily quality inspections on raw materials (cement, aggregate, admixtures, rebar/wire mesh) and finished precast products
• Conduct concrete testing including slump tests, air content, compressive strength (cylinder breaks), and unit weight in accordance with ASTM and NPCA/PCI standards
• Monitor batch plant operations to verify mix designs are being followed accurately
• Inspect forms, reinforcement placement, and dimensional tolerances prior to and during casting
• Document inspection results, non-conformances, and corrective actions using QC logs and reporting software
• Support NPCA Plant Certification and/or PCI Certification compliance and prepare for third-party audits
• Identify and flag production issues (voids, honeycombing, cracking, dimensional deviations) and coordinate corrective actions with production supervisors
• Maintain calibration records for testing equipment
• Train production staff on quality standards and best practices as needed
• Maintain accurate curing records, including steam-curing schedules where applicable
• Ensure proper labeling, tagging, and traceability of finished products

• 2+ years of quality control experience in precast concrete, ready-mix, or related concrete manufacturing environment
• ACI Concrete Field Testing Technician certification (Grade I minimum) required or ability to obtain within [60/90] days
• NPCA QC certification preferred
• Working knowledge of ASTM standards relevant to precast (e.g., ASTM C1577, C478, C858, or similar depending on product line)
• 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)

• 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
