Concrete Lab Technician

We are looking for a highly detail-oriented and organized Concrete Laboratory Technician to support our work in architectural UHPC (Ultra-High Performance Concrete) and GFRC (Glass Fiber Reinforced Concrete). This role is critical to ensuring material performance, consistency, and quality for cutting-edge façade and cladding applications. The ideal candidate is meticulous, process-driven, and thrives in a lab environment where accuracy and repeatability are essential.

• Prepare, mix, cast, cure, and test UHPC and GFRC samples in accordance with ASTM, PCI, and internal testing protocols.
• Conduct physical and mechanical testing including compressive strength, flexural strength (MOR/LOP), tensile testing, fiber dispersion, and dimensional stability.
• Support mix design development, including batching precision, raw material evaluations, pigment/color applications, and rheology testing.
• Assist in developing and maintaining a quality database for mix performance, batch records, and testing results.
• Operate, calibrate, and maintain laboratory equipment such as mixers, scales, curing chambers, compression/flexural test machines, and others.
• Maintain rigorous documentation of all testing activities to ensure traceability and reproducibility.
• Work closely with engineers and production teams to translate lab findings into scalable manufacturing processes.
• Support raw material supplier evaluations, sample sourcing, and material characterization.
• Ensure compliance with lab safety protocols, quality standards, and certification requirements.

• High school diploma or associate degree in materials science, civil engineering, or a related technical field (bachelor’s degree preferred but not required).
• Hands-on experience in a cementitious materials laboratory (UHPC, GFRC, precast, or concrete preferred).
• ACI Laboratory Technician certification (Level 1 or higher) is a strong plus.
• Proven ability to follow testing standards (ASTM, PCI, ACI) with high precision.
• Strong organizational skills and ability to manage multiple samples and tests simultaneously.
• Excellent attention to detail with a disciplined approach to data recording and reporting.
• Ability to work independently and collaboratively in a fast-paced R&D and production support environment.
• Commitment to safety and quality in all lab practices.

• Ability to lift up to 50 lbs. and handle heavy molds, raw materials, and samples.
• Comfortable working around industrial mixers, curing equipment, and testing machinery.
• Ability to stand for extended periods and work in varying temperature and humidity conditions.
