• Adhere to all laboratory safety policies, including proper use of personal protective equipment (PPE) and safe handling of samples, equipment, and materials.

• Strong attention to detail and the ability to follow standardized testing procedures with consistency and accuracy.
• Comfortable working in a fast‑paced environment with repetitive tasks that require precision and organization.
• Interest in geotechnical engineering, construction materials, soil science, or related fields.
• Commitment to maintaining high standards of safety, quality assurance, and data integrity.

• High school diploma or equivalent required; associate degree or technical coursework in engineering, geology, construction science, or a related field preferred.
• 0–3 years of experience in construction materials testing, geotechnical laboratory work, or a related field (prior laboratory experience preferred but not required).
• Commitment to workplace safety, following OSHA, company, and laboratory safety protocols, including the proper use of personal protective equipment (PPE).
• Basic computer proficiency, with experience in Microsoft Office (Excel, Word, Outlook) and Field Data Collection (FDC) software preferred.
• Ability to read, write, and interpret procedures, manuals, technical documents, and reports related to construction materials testing and laboratory protocols.
• Mathematical skills sufficient to add, subtract, multiply, and divide in all units of measure, using whole numbers, common fractions, and decimals.
• Effective verbal and written communication skills, with the ability to collaborate with colleagues, supervisors, field personnel, and clients to carry out instructions and report findings.
• Strong organizational, time‑management, and problem‑solving skills, with the ability to manage multiple tasks efficiently.
• Detail‑oriented and quality‑focused, ensuring accuracy in sample preparation, testing procedures, and data documentation.
• Ability to work independently within the limitations of experience, using initiative to solve routine lab challenges.
