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 within a fast-paced GMP environment. You will contribute to the development, qualification and execution of analytical methods supporting GMP release and characterization testing. Additionally, you 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 molecular 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 analytical assay development ensuring they are robust enough for qualification, transition to quality control and successful implementation.   * Perform general laboratory tasks, including maintenance and troubleshooting 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.   Landmark Bio is an Equal Opportunity, Affirmative Action employer.
