What are the responsibilities and job description for the Quality Control Lab Technician position at United Concrete?
Join our in-house concrete laboratory and QC team supporting precast and prestressed products for DOT, marine, port, and infrastructure projects across New England. This is more than a testing job—our lab does mix-design development, surface resistivity and permeability testing, and temperature-matched curing that most concrete labs never touch.
If you have a strong interest in concrete technology and want to grow, this role offers a defined path from Technician → Senior Technician → QC Specialist, with training and ACI certification support along the way.
Why Join Us
- Clear career progression with hands-on training and paid ACI certifications
- Advanced lab: mix design, durability testing, temperature-matched curing, applied R&D
- High-profile DOT and marine projects
- Stable, year-round work with a collaborative QC, production, and engineering team
- [Benefits: health/dental/vision, 401(k) match, PTO, paid holidays]
What You'll Do
- Sample and test raw materials (cement, aggregates, water, admixtures) for spec compliance
- Perform fresh concrete testing—slump, air, temperature, unit weight—per ASTM, ACI, and DOT requirements
- Cast, cure, and compression-test cylinders and other specimens
- Assist with mix-design development, optimization, and troubleshooting
- Perform QC testing on precast and prestressed products
- Maintain accurate test records and QC documentation
- Review test data to spot trends or quality issues and report to QC management
- Help investigate nonconformances and corrective actions
- Maintain and calibrate lab equipment; keep a clean, safe lab
- Participate in R&D of new materials, mix designs, and QC methods
Career Path
QC Technician → materials and fresh concrete testing, strength testing, documentation Senior QC Technician → mix-design trials, durability testing, data analysis, mentoring QC Specialist → mix-design development, nonconformance investigations, spec review, R&D
Advancement is based on skill, certifications, and performance—not just time served.
