Job Responsibilities 1. Lead the technical evaluation and experimental design of customized Assay Cell Line and CRISPR projects. Translate client requirements into executable technical plans and define project milestones, acceptance criteria, and key technical risks. 2. Provide end-to-end technical leadership for related projects, including host cell and construct selection, transfection or viral transduction, gene editing, antibiotic selection, cell enrichment or sorting, stable pool or single-clone generation, and genotypic and functional validation. 3. Lead critical data review, technical troubleshooting, and risk management for complex projects. Collaborate with project management, production, QC, and other relevant teams to ensure the timely and high-quality delivery of multiple projects, and participate in technical communication with key clients. 4. Establish and optimize technical workflows and SOPs, and train and mentor production specialists. Partner with business teams on technical training, service promotion, project evaluation, and client technical support to expand the market application of cell line development services. 5. Monitor emerging technologies, industry trends, and market opportunities in cell engineering, gene editing, and cell-based functional assays. Propose platform improvement initiatives based on customer needs and market insights, and support the evaluation of new technologies and the development of new methods and platforms. Qualifications 1. PhD in Cell Biology, Molecular Biology, Immunology, Bioengineering, or a related field, with at least five years of relevant research or professional experience, including doctoral or postdoctoral research. Experience in a CRO or life-science service organization is preferred. 2. Strong technical expertise in either Assay Cell Line development or CRISPR cell engineering, with demonstrated hands-on project experience in the other area. 3. Demonstrated experience in mammalian cell culture and stable cell line development using HEK293, CHO, or other commonly used cell lines, including plasmid transfection, viral transduction, antibiotic selection, and stable pool or single-clone development. 4. Hands-on experience with CRISPR-mediated gene knockout or knock-in, flow cytometry, cell sorting, and cell-based functional assays. Experience with FACS-based binding assays, competition assays, reporter assays, or other functional assays is preferred. 5. Strong capabilities in experimental design, data analysis, technical troubleshooting, parallel project management, and client communication. Professional proficiency in English and Chinese, together with effective training and cross-functional collaboration skills, is required.
