QC Analyst 1

On-site Watertown, United States

The Quality Control -   Analytics  department  supports  a growing portfolio of  cell and gene therapy  (CGT)   products , including CAR-T, iPSC, AAV, LVV and synthetic DNA products. We  are  immediately  recruiting for a  highly motivated  QC Analyst  I  to perform laboratory testing  with distinct technical but complementary focus  with in a fast-paced GMP environment .  You will  contribute to the development, qualification and execution of analytical methods supporting GMP release and characterization testing.  Additionally, y ou will work cross-functionally with Analytical  / Process  Development , Manufacturing, and Quality Assurance  to ensure methods meet regulatory and compendial expectations while supporting patient safety.  This is an outstanding opportunity for a candidate to  work under the guidance of a supervisor  and mentor , manage time effectively, complete assigned analytical  tasks   in a cross-functional collaborative environment supporting development and cGMP manufacturing of cell and gene therapies.   

This role focuses on the development and optimization of  UHPLC-based  biophysical  analytical methods and/or PCR-based, and related mo lecular methods  supporting CGT  safety, identity,  purity ,  strength  and  quality  testing , including   residual impurity and  compendial  applications such as Mycoplasma detection .      

    Scope of Responsibilities  

    • Complete required read/understand courses, bench-work training and quality-controlled cGMP documentation requirements.  

    • Execute assigned analytical test methods, with cGMP compliance, to support cell therapy manufacturing, vector manufacturing, and fill finish.  

    • Support a nalytical assay  development  ensuring they are robust enough for qualification ,  transition to  quality control  and successful implem e ntation .    

    • Perform general laboratory tasks, including maintenance and t roubleshooting  of equipment.  

    • Maintain accurate and reliable records, electronic lab notebook entries, and all other pertinent documentation.  

    • Comply with all environmental health and safety standards.  

    • This is a hands-on lab-based position requiring flexibility based on cell & gene therapy drug product manufacturing schedule.   

    • UHPLC-Based Methods  (Purity and Residual Analysis)  

    • Develop, optimize, and troubleshoot UHPLC-based methods (e.g., reverse phase, ion-pair, size exclusion etc.) for purity analysis of small molecules, DNA, RNA, and related CGT residuals.   

    • Apply molecular biology and biophysical characterization techniques to support method development.   

    • Support technical transfer and method qualification activities.  

    • Generate and review technical protocols, reports and GMP documentation. Troubleshoot chromatographic performance issues (e.g., peak shouldering, tailing, resolution) and propose corrective strategies.  

    • PCR-Based Methods  (qPCR / dPCR/ ddPCR)  

    • Develop and optimize PCR methods applicable to CGT drug substance/drug product testing.  

    • Support compendial and non-compendial molecular testing.  

    • Support method transfer, qualification and troubleshooting activities.  

    • Generate and review technical protocols, reports and GMP-compliant documentation  

    • Proteomic and/or Cell-based Methods    

    • Contribute to assay development activities using cell-based and/or proteomics-based approaches, e.g., cell culture-based cytotoxicity assays, flow cytometry, ELISA/plate-reader-based assays as applicable to CGT QC.  

    Required Experiences  

    • Hands-on operation of UHPLC instrumentation (e.g., Agilent, Water’s platform) in a regulated or research setting.  

    • Working knowledge of molecular biology and/or biophysical characterization techniques applicable to DNA, RNA, or plasmid characterization.  

    • Hands-on experience with PCR platforms and related molecular assays.  

    • Working knowledge of proteomic or cell-based techniques used in CGT QC.  

    • Familiarity with compendial methods is a plus.  

    Minimum Qualification  

    • QC Analyst I: Bachelors with minimum of 2 years or Masters with minimum of 1 year of relevant work experience, preferably in a cGMP biotechnology manufacturing environment, ideally with hands-on experience in cell and/or gene therapy.  

    • Demonstrate working knowledge of cGMP requirements.  

    • Ability to manage and prioritize tasks and projects, with the guidance of management.  

    • Strong verbal and written communication skills.  

    • Strong leadership skills, with an excitement to both roll up your sleeves and be a thoughtful partner.  

    • Detail-oriented with strong problem solving and troubleshooting skills.  

    • Applicants must possess valid, unrestricted work authorization and be available to commence work immediately upon offer.   

To Apply  

Please submit your resume/CV along with a brief cover letter describing your relevant experience for one or more applicable areas indicated above. Your cover letter should specifically address:  

  • Your hands-on experience with relevant technique  

  • Any additional relevant experience  

  • Your familiarity with GMP and regulatory framework applicable to CGT analytical testing.
