What does a quality assurance incoming inspector do?

A Quality Assurance Incoming Inspector is responsible for inspecting and verifying the quality of raw materials, components, or products as they arrive from suppliers before they are used in the manufacturing process. They check for defects, compliance with specifications, and adherence to quality standards. Their role helps ensure that only materials that meet company criteria are used, which helps prevent production issues and maintains product quality. Inspectors typically use measuring tools, review documentation, and may create reports on their findings.

What are the key skills and qualifications needed to thrive as a quality assurance incoming inspector?

To thrive as a Quality Assurance Incoming Inspector, you need strong attention to detail, knowledge of quality control standards, and often a background in manufacturing or a related technical field. Familiarity with measurement tools (calipers, micrometers), inspection software, and sometimes certifications such as ASQ Certified Quality Inspector are typically required. Excellent documentation skills, problem-solving abilities, and clear communication are essential soft skills in this role. These skills and qualifications ensure accurate verification of incoming materials, support compliance with quality standards, and help prevent defects in the manufacturing process.

What are some typical challenges faced by quality assurance incoming inspectors when evaluating new materials or components?

Quality Assurance Incoming Inspectors often encounter challenges such as identifying subtle defects in large batches, understanding complex technical specifications, and keeping up with evolving quality standards. They must work closely with suppliers and internal teams to resolve discrepancies and ensure that all incoming materials meet strict requirements. Managing time effectively to inspect high volumes without sacrificing accuracy is also a critical aspect of the role.

Job description

About the Role

CTK OTC Laboratories is seeking an experienced Quality Control Manager to lead our QC laboratory operations for OTC monograph drug and cosmetic products. Reporting to the QD Director, you will oversee physicochemical and microbiological testing, the stability program, environmental monitoring execution, and laboratory data integrity. You will determine technical conformance of tested materials, lead Phase I laboratory investigations of OOS/OOT results, and develop specifications and analytical methods — all in compliance with 21 CFR 210/211 and FDA OOS Guidance.


You will directly supervise the QC Laboratory Technicians and the Package Incoming Inspector, and own the day-to-day performance of the QC laboratory.


What You'll Do

  • Manage physicochemical testing of raw materials, in-process materials, and finished products, and perform first-level review of results
  • Manage microbial limit testing and environmental monitoring (EM) execution
  • Determine technical conformance of raw materials, packaging components, and in-process materials, and report results to QA for disposition
  • Operate the stability testing program, manage stability results, and recommend expiration dating
  • Develop specifications and technical justifications for raw materials, in-process materials, finished products, and purified water for QA approval
  • Execute and technically review analytical method validation protocols and reports
  • Lead OOS/OOT Phase I laboratory investigations and support QA-led Phase II investigations
  • Perform first-level review of electronic data audit trails and oversee laboratory system CSV
  • Manage laboratory instrument calibration, maintenance, and the Daily Verification program
  • Oversee reference standards, reagents, and retain sample management
  • Manage purified water testing and monitoring, and monitor storage/stability chamber conditions
  • Execute tamper-evident packaging inspection (21 CFR 211.132) and testing/quality evaluation of returned and recalled products
  • Manage laboratory data integrity (ALCOA+) compliance and provide trend data for the Annual Product Review


Leadership Responsibilities

  • Directly supervise, train, and evaluate the QC Laboratory Technicians and the Package Incoming Inspector
  • Develop and manage QC test method, instrument, and laboratory job-specific training programs (new-hire and periodic refresher)
  • Set day-to-day priorities and workload across the QC laboratory to meet testing and release timelines
  • Build a strong laboratory culture of accurate, contemporaneous documentation and prompt escalation of atypical results


Education & Experience

  • Bachelor's degree in Chemistry, Pharmacy, Pharmaceutical Sciences, Microbiology, Biology, Chemical Engineering preferred but not required
  • Substantial hands-on QC laboratory experience in a cGMP-regulated environment (OTC drug, pharmaceutical, cosmetic, or dietary supplement), including supervisory or managerial experience
  • Demonstrated experience with analytical instrumentation (HPLC/UPLC, GC, UV-Vis, FTIR, Karl Fischer, viscometer) and wet chemistry methods
  • Demonstrated experience with method validation/verification, stability program operation, and microbial limit testing
  • Experience leading Phase I laboratory OOS investigations and preparing investigation reports
  • Experience with laboratory data integrity remediation and audit trail review preferred


Knowledge, Skills & Abilities

  • Thorough working knowledge of 21 CFR Parts 210, 211, and 11, USP general chapters, and FDA OOS Guidance
  • Ability to critically evaluate analytical data and distinguish laboratory error from manufacturing-related causes
  • Ability to author and review specifications, test methods, validation protocols, and investigation reports in English
  • Competent with Microsoft Word, Excel, Outlook, PDF tools, and electronic document/record and inventory systems
  • Proficiency with chromatographic data systems and laboratory electronic records, including audit trail review
  • Effective supervisory and training skills for laboratory personnel
  • Bilingual English/Korean or English/Spanish is a plus


Regulatory Scope

This position determines technical conformance for materials and products tested by the QC laboratory, with final disposition authority resting with QA. The role supports compliance with laboratory controls (21 CFR 211.160–211.167), stability testing (211.166), tamper-evident packaging (211.132), electronic records (Part 11), and data supporting the Annual Product Review (211.180–211.198).


Benefits

  • Health Insurance — premium 100% covered by employer for the employee
  • Paid Time Off (PTO)
  • Paid holidays
  • Annual floating holiday
