Description

Join our Mission to Protect Humankind! Vaxcyte is a clinical-stage vaccine innovation company engineering high-fidelity vaccines to protect humankind from the consequences of bacterial diseases, which have serious and costly health consequences when left unchecked. Working to eradicate or treat bacterial infections such as invasive pneumococcal disease, Group A Strep, and Shigella is just the beginning. Our path to success is clear and well-defined, and Vaxcyte is set up to go the distance. WHAT we do is every bit as important as HOW we do it! Our work together is guided by four enduring core values: *RETHINK CONVENTION: We bring creative and intellectual diversity to every facet of the work we do in order to innovate and re-innovate the way vaccines are delivered. *AIM HIGH: We embody our collectively audacious goal to courageously make the most complex biologics ever attempted to protect humankind. *LEAD WITH HEART: Everyone leads at Vaxcyte with a kindness-first, inclusive approach to collaboration and vigorous debate that advances our business objectives. *MODEL EXCELLENCE: The magnitude of our challenge requires our shared commitment to demonstrating integrity, accountability, equality and clarity across communications and decision making. Summary: Vaxcyte is seeking an Associate Scientist II (contract), Research, to support the research and development of a novel bacterial polysaccharide conjugate vaccine. Specifically, this role will contribute to the setup, synthesis, purification, and analytical characterization of chemically modified polysaccharides and polysaccharide-protein conjugates. The ideal candidate will have an excellent understanding of conjugation process development, analytical chemistry principles, and substantial hands-on laboratory experience. The successful candidate will be expected to independently optimize and troubleshoot upstream and downstream conjugation processing procedures with minimal guidance. The candidate will also contribute across a range of related areas, including analytical development, stability studies, and process optimization initiatives. Responsibilities will also include record management, presenting data at group meetings, and contributing to the authorship of laboratory protocols and development reports. Essential Functions: Set up, optimize, and troubleshoot multi-step syntheses of protein-polysaccharide conjugates using click-chemistry and other related chemistries. Purify polysaccharides and conjugates using a variety of methods, including dialysis, FPLC chromatography, and tangential flow filtration (TFF). Characterize protein/polysaccharide/conjugates using different analytical methods, including SDS-PAGE gel, Western blotting, ELISA, HPLC, SEC-MALS, colorimetric and dynamic binding assays, et al. Apply Design of Experiments (DoE) principles; design, execute, and interpret statistically modeled experiments using DoE software. Proactively contribute scientific ideas, experimental strategies, and process improvements. Independently review and summarize relevant scientific literature to inform experimental design. Maintain highly organized records and Benchling entries to enable optimization and assessment of reproducibility. Analyze, interpret, and clearly communicate experimental data, including identifying trends, anomalies, and recommending next steps. Execute established protocols with limited oversight, demonstrating strong technical proficiency. Support team in routine laboratory activities and instrument maintenance.
