Job Title: CMC Principal Statistician- Vaccines

Location: Waltham, MA

About the Job

As an experienced mRNA CMC Principal Statistician, you will lead and coordinate the team providing statistical support to the mRNA CoE scientists / SMEs (Subject Matter Experts)/engineers for process, formulation and analytics of mRNA Drug Substance (DS) and Drug Product (DP); as part of the Data and Computational Science team in the mRNA CoE. This team brings end to end data integration and advanced analytics (pre-clinical, biomarkers, process development, CMC, clinical) in the mRNA CoE. Deploying and exploiting digital solutions (AI/machine learning, data, analytics) to integrate the full data value chain, extracting actionable information for a move to a full data driven strategy and decision-making process, to increase probability of success and to accelerate mRNA vaccines and therapeutics development and launch.

We are an innovative global healthcare company that helps the world stay ahead of infectious diseases by delivering more than 500 million vaccine doses a year. Across different countries, our talented teams are exploring new technologies to protect people and promote healthy communities.
