Job Details

Company Profile:

Vaxcyte, Inc. (Nasdaq: PCVX) is a vaccine innovation company engineering high-fidelity vaccines to protect humankind from the consequences of bacterial diseases. The Company is developing broad-spectrum conjugate and novel protein vaccines to prevent or treat bacterial infectious diseases. Vaxcyte’s lead candidate, VAX-24, is a 24-valent, broad-spectrum pneumococcal conjugate vaccine being developed for the prevention of invasive pneumococcal disease (IPD). The Company is re-engineering the way highly complex immunizations are made through modern synthetic techniques, including advanced chemistry and our exclusively licensed XpressCFTM cell-free protein synthesis platform. Unlike conventional cell-based approaches, the Company’s system for producing difficult-to-make proteins and antigens is intended to accelerate its ability to efficiently create and deliver high-fidelity vaccines with enhanced immunological benefits. Vaxcyte’s pipeline also includes VAX-XP, a PCV with an expanded breadth of coverage of greater than 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. The Company is driven to eradicate or treat invasive bacterial infections, which have serious and costly health consequences when left unchecked. For more information, visit
Vaxcyte, headquartered in San Carlos, CA, went public in June 2020 and currently has a team of approximately 100 employees and anticipates continued, significant growth. On January 6, 2022, Vaxcyte announced that the U.S. Food and Drug Administration (FDA) had cleared the Investigational New Drug (IND) application for VAX-24, its lead vaccine candidate. The Company initiated the VAX-24 Phase 1/2 clinical proof-of-concept study in adults in the first quarter of 2022 and expects to announce Phase 2 topline immunogenicity, safety, and tolerability results by the end of the year. VAX-24 was designed to prevent IPD, which can be most serious for infants, young children, older adults and those with immune deficiencies or certain chronic health conditions. Given the global impact of pneumococcal disease remains significant, the public health community continues to advocate for vaccines that can offer broader protection to prevent IPD. Vaxcyte’s PCV franchise, consisting of VAX-24 and VAX-XP, is designed specifically to address this need and has the potential to deliver the broadest protection for this very serious disease.
We are looking for a Senior Engineer with late-stage clinical or commercial experience in manufacturing, process characterization, and process validation. The successful candidate must have the ability to work in a highly collaborative manner with both internal teams and our CMOs. We are looking for an outstanding team player with excellent communication skills to join the polysaccharide development and manufacturing group within the CMC team.
The Senior Engineer will work collaboratively with the process development team responsible for early-stage polysaccharide development and process optimization. The Senior Engineer will work with the team to define an appropriate process optimization and characterization strategy for the polysaccharide intermediates. This person will play a critical role in overseeing CMO activities including process transfer, process implementation, process validation and implementation of a process control strategy at the commercial facility to support BLA filing and commercial launch. The candidate should have demonstrated experience with overseeing manufacturing operations, root cause analysis, risk assessments, and identifying critical and non-critical performance parameters. This is a great opportunity to make an impact and interact cross-functionally to take Vaxcyte’s lead program to the next level toward the company’s first licensure application.
