Quality Control Analyst
Job Description
The Quality Control Analyst performs physical property testing and wet chemistry testing on raw materials, in-process samples, and finished products, and progressively assumes responsibility for a full range of analytical testing, including chromatographic methods. This role prioritizes daily sample testing in a high-throughput environment, ensures the accuracy and completeness of laboratory and compounding records, and supports investigations into out-of-specification and out-of-trend results as well as customer complaints. The analyst works closely with production, engineering, and quality teams to maintain compliance with Good Manufacturing Practices (GMP) and Good Documentation Practices (GDP) while contributing to continuous improvement of laboratory methods, systems, and processes.
Responsibilities
Perform laboratory analysis on incoming raw materials, in-process samples, and finished products according to established procedures, including physical property testing and wet chemistry methods such as viscosity, pH, and total organic carbon (TOC) for water testing.Conduct analytical testing using chromatographic techniques, including GC and HPLC, and become proficient in routine operation, integration, and result calculations for these instruments.Prioritize and execute daily sample testing to support bulk formula batches and line samples, ensuring timely turnaround in a high-throughput laboratory environment.Prepare samples for chromatographic analysis, including preparation of standard and reagent solutions in accordance with laboratory protocols.Access, input, and retrieve data from the Laboratory Information Management System (LIMS) to manage sample information, test results, and product disposition.Review compounding and laboratory records for accuracy and completeness, ensuring compliance with Good Documentation Practices (GDP) and Good Manufacturing Practices (GMP).Disposition raw materials, in-process samples, and finished products for use or sale based on test results and established specifications.Document deviations in performance or results that are not anticipated or indicated in test procedures, and communicate findings to appropriate quality personnel.Assist with investigations of out-of-specification (OOS) and out-of-trend (OOT) results, as well as customer complaints, by performing additional testing, data review, and documentation as required.Support method development protocols by conducting requisite testing, documenting results, and providing feedback on method performance.Assist with instrument qualification and validation activities, including IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification), as well as calibration tasks.Participate in method transfer protocols by performing comparative testing and ensuring methods are implemented consistently across laboratories or sites.Assist with annual and new supplier validation protocols, including sample transfer, testing, and documentation to qualify new materials or suppliers.Contribute to the creation, review, and revision of Standard Operating Procedures (SOPs) to ensure laboratory practices are clearly defined and up to date.Support stability studies by following stability protocols, performing scheduled testing, and documenting results in accordance with regulatory and internal requirements.Assist with ordering laboratory supplies and services to ensure adequate inventory and proper functioning of the laboratory.Support contract manufacturing workflows by performing required testing, documentation, and communication related to contract-produced materials or products.Perform routine instrument maintenance and assist with troubleshooting laboratory equipment to minimize downtime and ensure data integrity.Handle laboratory clean-up and housekeeping duties, including proper waste disposal and glassware washing, to maintain a safe and orderly work environment.Coordinate information flow within the laboratory and with internal customers, including production, mechanics, engineers, and quality assurance, to ensure clear communication and smooth operations.Collaborate with teammates across shifts to effectively "pass the baton" by communicating ongoing work, issues, and priorities to ensure continuity of testing and investigations.Work independently with minimal oversight, demonstrating strong problem-solving skills and escalating issues appropriately when they exceed individual authority or expertise.
Essential Skills
Bachelor’s degree minimum in Chemistry preferred, or in Biochemistry, Biology with a Chemistry minor, or a closely related science discipline.Strong preference for at least 1 year of experience in a quality control laboratory with exposure to physical testing and volumetric solution sample preparation.Experience working under Good Manufacturing Practices (GMP) and Good Documentation Practices (GDP).Exposure to Laboratory Information Management Systems (LIMS) or other laboratory sample management systems.Demonstrated proficiency in wet chemistry techniques, including tests such as viscosity, pH, and TOC for water testing.Experience or training in analytical techniques such as gas chromatography (GC) and high-performance liquid chromatography (HPLC), or strong aptitude and willingness to learn these methods.Ability to thrive in a high-throughput environment while performing repetitive testing both quickly and accurately.Strong multi-tasking skills with the ability to prioritize and re-prioritize work based on changing needs and production demands.Ability to work independently with minimal supervision, demonstrating confidence in decision-making and problem-solving.Effective communication skills to interact with compounding and manufacturing leadership, as well as cross-functional teams.Ability to work at a fast pace under tight deadlines while maintaining accuracy and compliance.General experience with Microsoft Office applications, including Word, Excel, Teams, and Outlook.Strong teamwork skills and the ability to coordinate effectively with colleagues on off shifts to ensure smooth handoffs between shifts.
Additional Skills & Qualifications
Master’s degree in Chemistry, Biochemistry, or a related science is welcome and considered an asset.Experience with titration and other classical analytical techniques.Prior involvement in OOS/OOT investigations and customer complaint investigations.Experience supporting method development, method transfer, and validation activities in a QC or analytical laboratory.Familiarity with IQ/OQ/PQ processes and instrument calibration practices.Experience with stability studies and related documentation.Exposure to supplier qualification or validation testing processes.Experience contributing to SOP creation, review, and revision.Demonstrated curiosity, adaptability, and willingness to learn new techniques and technologies.Ability to communicate effectively with production workers, mechanics, engineers, QA, and other internal stakeholders.Comfort working in a team-oriented environment that emphasizes collaboration, mutual support, and shared accountability.Entry-level candidates with strong demonstrated chemistry skills and a solid academic foundation will be considered.
Work Environment
This position operates primarily in a clean laboratory setting with occasional work on the manufacturing floor to collect or verify samples. The role follows a second-shift schedule, Monday through Friday from 2:00 p.m. to 11:00 p.m., with a one-hour lunch break. Initial training occurs on a first-shift schedule, Monday through Friday, for approximately 2 to 4 weeks, depending on the candidate’s progress and training needs. The laboratory supports a manufacturing facility that produces a range of finished products, including hand sanitizers, soaps, dish soaps, nail polish remover, and other household cleaning products. Although the facility focuses on finished goods, the laboratory operates like a raw materials and in-process lab, emphasizing rapid turnaround and high throughput of quality testing. The team consists of approximately 12 analysts across three shifts and weekends, forming a smaller, close-knit group that works collaboratively and supports one another. The facility has recently undergone an FDA audit and is implementing enhancements to quality and manufacturing processes across all product lines, offering exposure to evolving quality systems and continuous improvement initiatives.
