Core Responsibilities

Primary Functions

Conduct comprehensive in-process and final inspections of products, materials, and components to ensure strict adherence to engineering drawings, technical specifications, and established quality standards.
Perform a variety of complex and precise tests on raw materials, in-process goods, and finished products, utilizing standard and specialized inspection equipment like calipers, micrometers, CMMs, and vision systems.
Meticulously document inspection and test results, maintaining accurate and organized quality records, test logs, and certificates of analysis in the Quality Management System (QMS).
Identify, document, and quarantine non-conforming materials or products, and initiate the non-conformance reporting (NCR) process to ensure deviations are properly controlled and dispositioned.
Investigate and analyze quality issues and customer complaints, participating in root cause analysis (RCA) activities to identify the source of defects and prevent recurrence.
Develop, review, and update standard operating procedures (SOPs), work instructions, and inspection plans to reflect current best practices and evolving quality requirements.
Collaborate closely with production, engineering, and supply chain teams to communicate quality findings and work together on implementing effective corrective and preventive actions (CAPA).
Calibrate, validate, and maintain inspection, measurement, and test equipment (IM&TE) to ensure accuracy and reliability, managing calibration schedules and records.
Participate in internal and external audits (e.g., ISO, FDA), preparing necessary documentation and speaking to quality control processes and records.
Train production staff and junior quality personnel on quality standards, inspection techniques, and the proper use of measurement tools to foster a culture of quality throughout the organization.
Monitor production processes and quality data trends using Statistical Process Control (SPC) charts and other analytical tools to identify potential shifts or drifts in process stability.
Manage the retention of quality samples and records in accordance with company policy and regulatory requirements, ensuring proper storage and traceability.
Review and approve supplier-provided documentation, such as certificates of conformance and material test reports, to verify the quality of incoming materials.
Assist in the qualification and validation of new equipment, processes, and products, executing test protocols and generating summary reports.
Generate and present regular quality metrics reports to management, highlighting key performance indicators (KPIs), trends, and areas for improvement.
Oversee the environmental monitoring program in controlled environments (where applicable), including collecting samples and coordinating testing for particulates and microbial contamination.
Author and execute protocols for stability studies on finished products, collecting data and analyzing results to determine product shelf life.

Champion continuous improvement initiatives within the QC department and aross the manufacturing floor, applying Lean and Six Sigma principles to enhance efficiency and reduce waste.
Serve as the quality subject matter expert on cross-functional project teams, providing critical input on design for manufacturability and inspectability.
Evaluate and approve batch production records, ensuring all steps were completed and documented according to cGMP and internal SOPs before product release.

Secondary Functions

Support ad-hoc quality data requests and exploratory data analysis to assist in troubleshooting and special investigations.
Contribute to the organization's overarching quality strategy and continuous improvement roadmap.
Collaborate with engineering and product development teams to translate new product designs into robust inspection and testing requirements.
Participate in daily team huddles, sprint planning, and other agile ceremonies to align QC activities with production priorities.
