Located in Valencia, California, within the Santa Clarita Valley, Lief Labs operates a state-of-the-art cGMP manufacturing facility that provides scalable and turnkey solutions geared toward helping entrepreneurial companies grow and succeed in the competitive dietary supplement market. With a focus on innovation, quality, safety, and regulatory compliance, Lief Labs' world-class research and development department consistently delivers innovative, great-tasting supplement formulations that align with market demands and consumer preferences.
The company prides itself on its commitment to quality control, production excellence, and continuous improvement. Its dynamic team includes experts dedicated to every stage of the product supply chain—from R&D to manufacturing to final product release—ensuring that customers receive products that meet the highest standards of safety and efficacy.
Lief Labs is currently seeking a highly skilled QC Microbiologist to join its Quality Control team at the Valencia facility. This full-time role offers a salary range of $74,000 to $88,000 annually, depending on the candidate’s experience, skills, and education. The QC Microbiologist role is ideal for professionals passionate about microbiology, product quality, and safety within a GMP-regulated environment, and who aspire to contribute meaningfully to the dietary supplement industry.
In this pivotal position, the QC Microbiologist will perform microbiological testing and analysis on various materials including raw ingredients, packaging components, in-process samples, and finished products. The role demands rigorous adherence to FDA, USP, and internal quality standards and involves maintenance of detailed laboratory documentation compliant with GMP, GLP, and data integrity principles. This role also serves as a critical resource assisting with environmental monitoring of air, surfaces, water, and personnel, while supporting cleaning validation, equipment qualification, and contamination control efforts.
Beyond testing and validation, the QC Microbiologist will lead or contribute to investigations involving nonconforming lab results or out-of-specification findings, executing root cause analyses and supporting corrective and preventive actions (CAPA). The ideal candidate will contribute technical expertise towards compliance efforts during audits, inspections, and customer complaint investigations, actively participating in writing and reviewing SOPs, protocols, and controlled documents.
This is a collaborative role, requiring effective partnerships with cross-functional teams such as Quality Assurance, Production, Sanitation, Research and Development, and Operations to uphold product safety and quality initiatives. The successful candidate will also support training programs related to microbiology, sanitation, and GMP for laboratory and production personnel, reinforcing a culture of quality and safety.
