Position Summary:
We are seeking a highly motivated Analytical Scientist to join our growing WuXi Vaccines team. The position level can be Scientist to Principal Scientist, depending on the experience of candidate. This individual will play a key role in designing and optimizing analytical methods for vaccine development. The scope of methodology includes qPCR, ELISA, next generation sequencing, and reporter gene-based potency assays, multiplex assay (e.g. MSD, Luminex) particle analysis, and other bioassay for characterization and release testing of vaccine or prophylactic biologics candidates. The ideal candidate will have a strong foundation in analytical development, excellent research capability, and the ability to work cross-functionally with internal and external stakeholders.
Key Responsibilities:
61 The Analytical Scientist will be involved in developing immunoassays and other analytical methods to support vaccine product development. Methods of consideration include but not limited to:
61 ELISA (binding and sandwich formats) ELISAs for antigen content, antibody responses, or potency
61 Cell-based assays (e.g., reporter gene assays, neutralization assays)
61 Quantitative PCR (qPCR or RT-qPCR) for nucleic acid-based vaccines or viral vector quantification.
61 Conduct literature research, design, develop, transfer, optimize, troubleshoot, and/or execute analytical of interest.
61 Maintain cell lines and perform neutralization or cell-based potency assays.
61 Collaborate closely with the Process Development and Business Development team to support process and/or business development. Provide technical support and generate data summary for business development, assay transfer and troubleshooting.
61 Drive the transfer of methods and processes from Process Development to manufacturing, Quality Control (QC), ensuring technical accuracy and regulatory compliance. Generate data summaries and contribute to technical documents and regulatory filings.
61 Work in compliance with biosafety and quality requirements. Maintain detailed and accurate documentation in compliance with company policies and regulatory guidelines.
61 Present data and project updates in internal and client meetings, demonstrating strong scientific communication skills.

Qualifications:
61 Ph.D. in Immunology, Molecular Biology, Virology, or related field (no industry experience required), or
61 Master’s degree with 2–5 years of hands-on laboratory experience in a bio/pharma/academic setting.
61 Strong technical skills in immunoassays and/or molecular techniques (e.g., qPCR). Solid hands-on experience in ELISA, qPCR, and basic cell culture techniques.
61 Familiarity with biological matrices (e.g., serum, cell lysates) and statistical data analysis.
61 Experience in vaccine development or viral vector testing is highly desirable.
61 Demonstrated ability to independently plan, execute, and troubleshoot experiments.
61 Experience with method transfer and technology handoffs to QC or GMP environments is a plus.
61 Excellent communication and interpersonal skills with the ability to work in a collaborative, fast-paced environment. Team-oriented with excellent communication and organizational skills.
