• A skilled process engineer with expertise in:
  • Molecule activation and bioconjugation (e.g., activation chemistries, conjugation reaction kinetics, in-process controls, and common side reactions/impurities)
  • Strong quantitative skills: trend and multivariate analysis of process and analytical data to support continued process verification (CPV), deviation investigations, and process characterization (e.g., DOE).
• An exceptional team player who works seamlessly with others, speaks up, and remains focused on achieving the best results to attain company goals.
• The ability to analyze data and communicate conclusions, decisions and recommendations concisely to key stakeholders.
• A strong sense of ownership and accountability; commitment to Vaxcyte’s mission of protecting humankind.

• Work cross functionally with program management, process development, quality, facilities, regulatory, finance, logistics, clinical supply, and CMO / supplier management to ensure manufacture under GMP of different protein-polysaccharide conjugate Drug Substances required for Vaxcyte’s vaccine portfolio.
• Execute statistical thinking and data analysis using: DOE planning/analysis, process capability, control charts/CPV trending, and clear data visualization; proficiency with common tools.
• Oversight of CMO service provider(s) to ensure delivery of commercial readiness, process validation, and commercial stage manufacturing campaigns.
• Enable MSAT DS team participation in technology transfer, equipment/technology procurement and qualification, late-stage process characterization, process validation, and deviation and deficiency investigations and troubleshooting.
• Lead all aspects of and engage in the planning, design, execution, and documentation of DS manufacturing process Investigations and CAPAs.
• Drive continuous improvement and change management in DS manufacturing processes through technological innovation and application of first principles in process engineering.
• Support the process to select new CMOs and suppliers.
• Leverage literature, industry/regulatory guidance, and practical experience to perform work and influence CMC strategies.
• Recommend and implement new technology that advances knowledge and productivity within the department. Drive continuous improvement.
• Author and review technical reports, manufacturing documents, regulatory submissions, and publications.
• Present at department, project team, and senior management meetings. May present externally at scientific conferences.
• Support the CMOs during inspections of health authorities where necessary and ensure proper follow-up of any potential observation or recommendation.

• PhD in Bio/Chemical Engineering or Microbiology/Chemistry/Biochemistry with 9+ years of relevant Pharma/Biotech industry experience, or Master’s degree in Bio/Chemical Engineering or Microbiology/Chemistry/ Biochemistry with 12+ years of relevant Pharma/Biotech industry experience. Other combinations of education and/or experience may be considered.
• Demonstrated capability in statistical thinking and data analysis: DOE planning/analysis, process capability, control charts/CPV trending, and clear data visualization; proficiency with common tools.
• Experience with Vaccine manufacturing operations preferred.
• Strong experience in Drug Substance Manufacturing under GMP regulations required. Understanding of Quality systems. Experience in Drug Substance manufacturing equipment specification and qualification preferred.
• Strong scientific or technological (process engineering) background and hands-on experience with biochemical reaction, product recovery, and purification processes. Commercial manufacturing experience preferred.
• Deep knowledge of protein‑polysaccharide conjugation principles (activation/coupling chemistries, reaction kinetics, impurity formation, and linkage distribution), plus understanding of CQAs and analytical characterization relevant to conjugates.
• Sound knowledge of product recovery unit operations such as homogenization/microfluidization, centrifugation, and depth filtration product purification unit operations such as chromatography, UF/DF TFF, and precipitation process analytics/control systems.
• Strong ability in troubleshooting equipment/technology and process. Adept at FMEA. Excellent analytic skills. Experience in Investigations and development and implementation of CAPAs preferred.
• Experience with facility fit assessment, facility start-up, technology transfer, process validation, and scale-down studies implementing DOE desired.
• Strong interpersonal and leadership skills. Ability to communicate effectively both verbally and in written formats. Experience with Cross-Functional teams and managing direct reports.
• Proven technical leadership skills including strong project management skills.
• Fluency in spoken and written English is highly preferred.
