Job Description
Position Summary SMS Biotech is a cell therapy company advancing an allogeneic stem-cell program for COPD, manufactured under cGMP at our Sorrento Valley biomanufacturing facility. We are seeking a hands-on Quality Control (QC) Associate to perform release and characterization testing of our cell therapy product, with a primary focus on potency assays and flow cytometry, and to perform final product vial inspection prior to shipment. The QC Associate is primarily responsible for executing potency assay testing and flow cytometry-based analysis, and for performing pre-shipment vial checks to confirm that finished product meets specification before release for distribution. The Associate will also support general laboratory associate duties (e.g., tissue culture, media and reagent preparation, sample management) as needed, but the core focus of the role is QC testing and final vial verification before shipping. We are looking for a detail-oriented, self-directed learner who thrives in a fast-paced, growing GMP environment. Key Responsibilities Potency & QC Analytical Testing
- Perform potency assay testing of cell therapy product to support lot release and stability, following approved SOPs and compendial/validated methods.
- Execute cell-based and analytical assays accurately and contemporaneously, recording all data per Good Documentation Practices (GDP).
- Prepare samples, standards, controls, reagents, and media required for potency and release testing; manage reference standards and controlled stocks.
- Review assay results against acceptance criteria; flag out-of-specification (OOS) or atypical results and support investigations, deviations, and CAPA as needed.
- Support method qualification, validation, and transfer for new or improved QC assays. Flow Cytometry
- Perform flow cytometry-based identity, viability, purity, and characterization testing of cell therapy product and in-process samples.
- Perform routine instrument startup, quality/calibration checks, and basic troubleshooting; escalate instrument issues and maintain instrument logs. Vial Inspection & Release for Shipment
- Perform final visual inspection and vial checks of finished product (e.g., fill, cap/crimp integrity, labeling, appearance, and absence of defects) prior to release for shipment.
- Verify that vials and associated documentation are complete, accurate, and meet specifications before product is released for distribution.
- Support cold-chain and Good Distribution Practice (GDP) requirements — confirm storage and shipping conditions (e.g., LN2/cryogenic or cold-chain), monitor temperature excursions, and ensure proper handling of cryopreserved product.
- Document release-for-shipment activities and partner with QA to ensure product is shipped only after all QC checks are satisfied. General Laboratory Support (as needed)
- Perform tissue culture/cell culture work in support of potency assays and routine QC operations, maintaining aseptic technique and cell-line health.
- Support media and reagent preparation, labeling, inventory, sample receipt and logging, and routine equipment maintenance and calibration.
- Assist manufacturing and laboratory associates with general lab tasks during peak workloads, while keeping QC testing and vial checks as the priority. Quality, Documentation & Data Integrity
- Execute all work in compliance with cGMP, applicable SOPs, and data integrity (ALCOA+) requirements.
- Maintain right-first-time, contemporaneous documentation in test records, logbooks, and electronic systems per GDP and Good Distribution Practice.
- Author and revise SOPs, forms, and test records; maintain equipment logs and calibration records.
- Support internal and regulatory (FDA) audit and inspection readiness for the QC function. Qualifications - Required
- Bachelor's degree in Biology, Biochemistry, Immunology, Microbiology, or a related life science.
- 1-3 years of hands-on laboratory experience, preferably in a GMP, pharmaceutical, biotech, or cell-therapy environment (relevant internship or co-op experience considered).
- Hands-on mammalian tissue culture/cell culture experience with strong aseptic technique.
- Experience with, or strong working knowledge of, flow cytometry (sample preparation, acquisition, and data analysis).
- Familiarity with cGMP documentation practices and data integrity (ALCOA+) principles.
- Strong attention to detail and the ability to perform precise, repeatable work and accurate, contemporaneous documentation.
- Ability to lift up to ~25 lbs, stand for extended periods, and perform detailed work requiring manual dexterity and color discrimination. Qualifications - Preferred
- Hands-on experience performing potency or other cell-based release assays in a regulated (GMP) setting.
- Experience with cryopreservation, LN2/cold-chain handling, and final product visual inspection or release activities.
- Working knowledge of 21 CFR Parts 210/211 and 1271, USP compendial methods, and ICH quality guidelines.
- Experience supporting method qualification/validation, technology transfer, or new-assay build-out.
- Valid driver's license and willingness to travel occasionally between the Sorrento Valley and San Marcos sites (mileage/travel reimbursement provided). What We're Looking For
- A self-starter and quick, independent learner who can pick up new assays and procedures with limited supervision.
- Comfortable working in a fast-paced, evolving environment and adapting to shifting priorities.
- Strong attention to detail, organization, and right-first-time documentation discipline.
- Reliable, accountable, and a collaborative team player who communicates clearly across functions.
- Flexibility to occasionally adjust hours to support manufacturing, testing, and shipping schedules. What We Offer
- Hands-on experience in a cGMP cell-therapy program with a clear path for skill and career growth.
- The opportunity to grow your scope across potency, flow cytometry, and final product release testing.
- Travel and mileage reimbursement for any cross-site travel between Sorrento Valley and San Marcos.
