Senior Data Scientist - Clinical AI development

About the Department

Our Research & Development organization brings together the best minds in life science innovation. The teams located in facilities in Lexington, Watertown, Cambridge and Plainsboro reflect the full R&D continuum, from early research through late-stage clinical development. Here, we are building for the future, creating a distinct R&D community based on collaboration, partnerships, and cutting-edge research across multiple modalities and therapeutic areas. We recognize that improving human health starts here and that patients rely on us. Our R&D hub merges biotech speed and agility with large pharmaceutical company quality, resources, and stability, uniting the best of both worlds to develop new medicines for patients.

 

The Position

The Senior Data Scientist II will contribute to the research team's effort towards exploring and creating new technology and being a world leader in data science within our fields. The Senior Data Scientist II will bring elements of data collection, preparation, and engineering as well as software engineering in a data science context. The Senior Data Scientist II will develop and validate algorithms and models in support of data science efforts with a high degree of initiative and self-sufficiency.  Moreover, the Senior Data Scientist II will guide more junior Data Scientists in the execution of their tasks, as well as supports them in networking in a complex global organization. 

Open to hiring at the Lead level commensurate with experience

Relationships

The Senior Data Scientist II reports to the Associate Director of the Clinical AI development area. Internal partners include fellow Data Scientists, AI Engineers, and System Architects who serve as primary day-to-day collaborators in the design and delivery of AI/ML solutions. The role also works closely with medical professionals, clinical trial squad members, and biostatisticians to ensure that solutions are grounded in clinical context and meets the needs of drug development workflows 

 

 

Essential Functions
