We are looking for an Optical Quality Technician that will play a critical role in our manufacturing facility by testing, documenting, and routing non-conforming eyeglass lenses. Operating at the intersection of quality control and laboratory operations, the Quality Technician uses precision optical measuring instruments to test lenses, inspect rejected lenses, identify the exact root cause of failure, and accurately record defect metrics in our Laboratory Management System (LMS). Reporting to the Quality Supervisor, this work directly ensures fast turnaround times for customer remakes while providing actionable quality data to prevent repeat manufacturing errors.

Please note: as a condition of employment for this role, you will be required to undergo pre-employment drug testing in accordance with our company policies and applicable law.

• Perform Detailed Inspection: Inspect non-conforming single-vision, progressive, and specialty lenses using manual lensometers, digital lens analyzers, calipers, photometers, and high-intensity bench lighting.
• Identify Root Causes: Determine precise failure points across manufacturing processes—including generator marks, wave/power errors, axis/prism errors, AR coating crazing, edger chips, or material defects.
• Verify Specifications: Cross-reference physical lenses against ANSI/ISO standards and original prescription job tickets.

• Log Defect Metrics: Promptly log non-conforming items into the Laboratory Management System (LMS) using standardized defect taxonomies and failure codes.
• Initiate Remakes: Authorize and generate immediate digital remake tickets to minimize overall job turnaround delays.
• Data Integrity: Ensure accurate attribution of defect origin (e.g., department, machine, shift, material, or operator) to maintain reliable quality reporting.

• Physical Tray Management: Maintain organized sorting bins for scrapped components and ensure proper hazardous/optical waste disposal protocols.
• Feedback Loop: Partner with cross-functional department supervisors to flag real-time defect spikes or machine calibration failures.
• Continuous Improvement: Participate in weekly quality reviews to analyze data and recommend process adjustments.

• Experience: Minimum of 1+ year in a manufacturing  environment. Must be able to demonstrate critical thinking and reasoning skills, and work independently with minimal supervision.
• Equipment Proficiency: Demonstrated ability to operate lensometers, thickness gauges,  optical layout systems, and precision testing equipment.
• Technical Aptitude: Experience working with optical Laboratory Management Systems and optical testing equipment.
• Attention to Detail: Excellent visual acuity (with or without vision correction) and fine visual discrimination under varied lighting conditions.
• Sound Judgment: Ability to ask thoughtful questions, respectfully challenge assumptions, and seek clarity when evaluating decisions or recommendations.

• Prior experience in Quality Assurance 
• Basic proficiency in Microsoft Office (specifically, Microsoft Excel)
• Strong understanding of lens optics, prescription variables (Sphere, Cylinder, Axis, Add Power, Prism), lens materials (CR-39, Polycarbonate, High-Index, Trivex), and coatings (AR, Photochromic, Hard Coat).

We strive to build a diverse team of individuals with a broad range of experience and perspectives. We encourage you to apply even if you don’t feel you meet all the qualifications.
