Job Details

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, periodontitis 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:

*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.

*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.

*MODEL EXCELLENCE:  The magnitude of our challenge requires our shared commitment to demonstrating integrity, accountability, equality and clarity across communications and decision making.


Vaxcyte is looking for an energetic and talented individual to join our Drug Product Analytics team. The candidate must have extensive knowledge and practical experience in analyzing and characterizing Biological Drug Products (proteins, polysaccharide conjugates, vaccines) using a number of techniques, including HPLC, CE, spectrophotometric techniques, light scattering and particle sizing techniques. This role will require an emphasis on next-generation, multiplexed immunoaffinity techniques (i.e., MSD, Luminex), so experience with this technology is a major benefit. While not necessary, experience in analyzing vaccine and adjuvant containing formulations is a plus.
The responsibilities will be primarily to develop analytical methods, biophysical characterization assays and coordinate routine testing in support of formulation development across all projects in the pipeline in all stages of development. The position will require managing a team of 3-4 scientists.
The candidate will work independently to develop analytical methods, perform analytical data review, authorship of protocols and reports, coordination and oversight during assay transfer with the Vaxcyte QC team and external CMO partner groups.
This will consist of:
·         Leading analytical method development and execution for Drug Product characterization including direct management of junior scientists.
·         Evaluate and develop the most appropriate biochemical and biophysical characterization tools to support biological drug product development, including adjuvanted vaccine drug products.
·         Support formulation selection and stability analysis of Intermediate and Drug Substance materials.
·         Apply biophysical characterization techniques to fully understand antigen/adjuvant interactions and to assess formulation matrix optimization options.
Vaxcyte is looking for an experienced and flexible individual who would be comfortable working on multiple projects at once, with fluid prioritization to enable aggressive timelines. This position is for a scientific role which will be partly lab based, whilst requiring excellent scientific judgement, independence, rigor and thorough record keeping.
    • BSc or MSc in Pharmaceutics, Chemistry, Biophysics or Biochemistry preferred, with >7 (with BSc) or >4 (with MSc) years of industrial experience; or PhD in Pharmaceutics, Chemistry, Biophysics or Biochemistry with >2 years of relevant experience.
    • The candidate will have had strong experience in characterization of Biological Drug Products containing proteins, polysaccharides and/or protein conjugate formulations. Experience in characterization of   vaccine systems containing adjuvants will be an advantage.
    • Strong experience in method development for immunoaffinity and multiplex immunoaffinity based assays (ELISA, MSD, Luminex, etc) is required. Experience in particle light scattering analysis (DLS, MALS) and HPLC based assays is a plus.
    • Demonstrated experience in authoring analytical technical documents, including method protocols and SOPs, assay transfer and implementation protocols and reports, validation protocols and reports.
    • Participated in method transfers to external vendors and to internal collaborators.
    • Strong scientific leadership is required: critical thinking, ability to present complex data sets and to independently propose and design follow-up experiments.
    • Managerial experience is of notable benefit.
    • The candidate should have high degrees of both flexibility and organizational skills as well as an eagerness and ability to learn to effectively navigate Vaxcyte’s multiple projects and timelines.
    • Strong interpersonal skills, ability to communicate effectively both verbally and in written formats are necessary to collaborate effectively with the rest of the Drug Product Development team and well as across other teams.
    • Detail oriented, rigorous and excellent skills in record keeping.

Reports to: Group Leader, Drug Product Analytics
Location: San Carlos, CA
The compensation package will be competitive and includes comprehensive benefits and an equity component.
Salary Range: $152,000 – $170,000


Vaxcyte, Inc. (Nasdaq: PCVX) is a next-generation vaccine company seeking to improve global health by developing superior and novel vaccines designed to prevent some of the most common and deadly infectious diseases worldwide. Our exclusively licensed cell-free protein synthesis platform and our proprietary know how enable us to design and produce optimized protein carriers and antigens, the critical building blocks of vaccines, in ways that we believe conventional vaccine technologies cannot. Our lead vaccine candidate, VAX-24, is a preclinical, 24-valent broad-spectrum pneumococcal conjugate vaccine (PCV) being developed for the prevention of invasive pneumococcal disease. Our pipeline also includes VAX-XP, a PCV with an expanded breadth of coverage of at least 30 strains; VAX-A1, a prophylactic vaccine candidate designed to prevent Group A Strep infections; and VAX-PG, a therapeutic vaccine candidate designed to slow or stop the progression of periodontal disease by targeting the keystone pathogen responsible for this chronic, oral inflammatory disease.
