Salary Range: $26.00 To $34.00 Hourly

Luna Innovations is hiring a Quality Inspector to join our Quality team in Chino, California. You’ll be the hands‑on quality gatekeeper for the optical components, optical test & measurement instruments, and terahertz measurement systems we design and manufacture—verifying that every incoming material, every in‑process assembly, and every piece of calibrated equipment meets the exacting standards our customers expect.

The photonics industry is in the middle of a historic growth cycle. Demand for high-performance optical components and precision test and measurement platforms is accelerating as AI datacenters scale, silicon photonics matures, and next-generation optical networks come online. Luna’s products are at the center of that momentum—and this role ensures they leave our facility ready to perform.

When a customer uses a Luna instrument to characterize a photonic integrated circuit or validate a 400G transceiver, they’re trusting that every component inside was built and inspected to specification. That trust starts with you. You’ll inspect incoming optical and mechanical components, verify in‑process assemblies against engineering drawings and specifications, and manage the metrology and calibration programs that keep our measurement capability traceable and audit‑ready.

Your work is the foundation of product quality at Luna.

• Perform incoming inspection of optical components, mechanical parts, electronic assemblies, and raw materials against engineering drawings, purchase order requirements, and approved vendor specifications.
• Conduct in-process inspections at key manufacturing stages ensuring conformance to work instructions and quality plans.
• Use precision measurement instruments (micrometers, calipers, optical power meters, multimeters, etc.) to verify dimensional, electrical, and optical specifications.
• Document inspection results accurately, generate inspection reports, and disposition non-conforming material through the NCR (Non-Conformance Report) process.
• Collaborate with manufacturing, engineering, and supply chain teams to resolve quality issues at the point of discovery, minimizing downstream impact.
• Collaborate with manufacturing to conduct Final Inspections or verify their proper completeness and adherence to appropriate inspection records, verifying Final Test parameters, and completion of CoC documentation.
• Support First Article Inspections (FAI) per AS9102 for new components and revised designs.

• Assist the Process Engineering team with the calibration program for inspection, test, and measurement equipment, ensuring all items are properly calibrated, labeled, and traceable to NIST or equivalent national standards.
• Assist with performing in-house calibrations where applicable.
• Evaluate measurement system capability (Gage R&R, measurement uncertainty analysis) and recommend improvements to inspection methods and tooling.
• Support the selection and procurement of new inspection equipment as product lines evolve.

• Support internal and external audits by providing inspection records, NCR data, and process documentation.
• Contribute to CAPA (Corrective and Preventive Action) investigations by providing inspection data and root cause analysis input.
• Identify trends in incoming and in-process quality data and recommend corrective actions to prevent recurrence.
• Help maintain and improve inspection procedures, work instructions, and acceptance criteria as products and processes evolve.

• Associate’s degree or technical certification in Quality, Manufacturing Technology, Engineering Technology, or a related field—or equivalent combination of education and experience.
• 2–5 years of experience in a manufacturing environment, preferably as a quality inspector in optics, photonics, electronics, or precision instrumentation.
