Olsson is seeking a driven and detail‑oriented individual to join our Construction Materials Testing (CMT) team in Oklahoma City. Our CMT Lab Technician plays a critical role in ensuring the quality, safety, and longevity of materials used in construction projects. In our lab, we analyze a variety of construction materials—including concrete, soil, and asphalt—to assess their strength, composition, and performance characteristics.

These tests are essential for verifying that materials meet rigorous safety and quality standards. By delivering accurate and dependable results, our lab plays a key role in helping clients comply with regulatory requirements and ensure the structural integrity and long‑term success of their projects.

In this role, you will be responsible for conducting routine laboratory testing of construction materials, meticulously preparing specimens for testing, and upholding high standards of quality control under the guidance of senior technical staff. You’ll also have the opportunity to pursue technician certifications through respected industry organizations such the American Concrete Institute (ACI).

The ideal candidate brings prior experience working in a CMT lab—particularly with soils and aggregates, is eager to learn, grow, and take on new challenges. Success in this role requires a proactive mindset, strong attention to detail, and a commitment to continuous improvement.
