Job summary

Ecology Auto Parts Inc. is seeking an experienced Aggregate & Materials Laboratory Manager to lead AMRG’s laboratory operations supporting aggregate production, rock and construction-material testing, QA/QC, and process control.

You will supervise personnel, manage sampling, testing, and reporting, and ensure compliance with testing standards. The ideal candidate has extensive experience in aggregate/industrial testing, strong leadership, and familiarity with ASTM/AASHTO procedures.

Qualifications

• Bachelor’s degree in Civil Engineering, Materials Science, Geology, Geological Engineering, Mining Engineering, Construction Materials, or related field; equivalent directly relevant laboratory experience may be considered.
• Five or more years of progressive aggregate, geotechnical, construction-materials, mining, quarry, materials-testing, or related laboratory experience.
• Demonstrated experience supervising or managing laboratory technicians, testing workflow, schedules, equipment, QA/QC, or technical operations.
• Strong knowledge of aggregate sampling, sieve analysis, gradation, moisture and density testing, physical-property testing, laboratory quality control, and technical documentation.
• Working knowledge of ASTM and AASHTO testing procedures applicable to aggregate and materials testing.
• Ability to review and interpret test results, specifications, quality-control data, and technical reports and communicate findings to operations and management.
• Experience with laboratory equipment calibration, preventative maintenance, documentation, and troubleshooting.
• Strong leadership, organization, communication, scheduling, problem-solving, and decision-making skills.
• Experience managing or supervising an aggregate, quarry, geotechnical, construction-materials, mining, or industrial testing laboratory.
• Experience with aggregate gradation, moisture-density, specific gravity and absorption, abrasion, durability, soundness, or related physical-property testing.
• Experience with laboratory accreditation, internal audits, equipment calibration programs, and quality-management systems.
• Experience developing laboratory SOPs, technician training programs, testing procedures, and QA/QC programs.
• Experience supporting aggregate production, crushing, screening, stockpile management, or plant quality-control operations.
• Relevant ACI, AASHTO, ASTM, state DOT, aggregate, materials-testing, or laboratory certifications are preferred.
• MSHA Part 48 certification or willingness to obtain upon hire.

Responsibilities

• Lead day-to-day operations of the aggregate and materials laboratory, including personnel, workflow, testing schedules, sample priorities, equipment availability, and reporting deadlines.
• Supervise laboratory technicians and provide training, work assignments, technical guidance, performance feedback, and competency verification.
• Coordinate laboratory workload and staffing levels with aggregate production, quarry, plant, project, customer, and operational requirements.
• Oversee representative sampling of aggregate, rock, stockpiles, feed material, processed material, and finished products.
• Establish and maintain procedures for sample identification, labeling, tracking, storage, splitting, drying, crushing, sieving, and other applicable preparation activities.
• Perform or oversee sieve analysis and aggregate gradation testing and evaluate results against applicable product, project, customer, and plant specifications.
• Perform or oversee moisture content, moisture-density, specific gravity, absorption, unit weight, particle characteristics, and other applicable physical-property testing.
• Coordinate abrasion, durability, soundness, and other specialized aggregate testing internally or through qualified outside laboratories when required.
• Support aggregate quality control by identifying material variation, out-of-specification results, stockpile inconsistencies, production trends, and potential corrective actions.
• Work with plant, quarry, processing, and operations personnel to evaluate crusher settings, screening performance, stockpile practices, product consistency, and other factors affecting aggregate quality.
• Ensure laboratory and field testing is performed in accordance with established procedures, applicable specifications, and relevant ASTM, AASHTO, agency, or customer requirements.
• Establish and maintain laboratory QA/QC procedures, control checks, repeat-testing criteria, documentation standards, and internal audit practices.
• Review laboratory data, test results, material certifications, and technical reports for accuracy, completeness, consistency, and compliance before release.
• Investigate abnormal, inconsistent, or out-of-specification results and coordinate resampling, retesting, process review, or corrective action as appropriate.
• Oversee operation, calibration, verification, preventive maintenance, troubleshooting, and repair coordination for sieves, balances, scales, ovens, moisture analyzers, crushers, splitters, shakers, and other laboratory equipment.
• Maintain calibration records, equipment logs, sample records, testing documentation, QA/QC records, certifications, and laboratory reports in an organized and traceable manner.
• Generate daily, weekly, monthly, and project-specific laboratory reports for operations and management and communicate material-quality trends or concerns promptly.
• Coordinate third-party laboratories, inspectors, customers, agencies, consultants, and testing providers when outside verification or specialized testing is required.
• Develop and maintain laboratory SOPs, training materials, testing procedures, quality-control programs, and continuity plans.
• Support laboratory inspections, audits, certifications, or accreditation activities when applicable.
• Maintain a clean, organized, safe, and compliant laboratory environment and enforce applicable MSHA, OSHA, environmental, equipment-safety, sample-handling, and company requirements.
