Summary:  

We are seeking a Data Scientist to support evidence generation across the medical device product lifecycle. This role, under the direction of the Manager of Biostatistics & Data Science, will transform real-world, clinical, and preclinical data into reliable, reproducible datasets, analyses, and insights that support research and cross functional business needs.  

The ideal candidate brings strong hands-on data science and statistical skills, with the ability to translate research questions into fit-for-purpose datasets and analytical approaches. The role will support both real-world data initiatives and the statistical execution of preclinical and clinical studies, including but not limited to study design, endpoint definition, analysis planning, statistical programming, data review, interpretation, and reporting.

In This Role, You Will: 

Data Science and Real-World Evidence 

• Translate research and business questions into cohort definitions, data requirements, analytic plans, and clear deliverables. 

• Work with real-world data, EHR records, claims data, clinical data, and other relevant data sources to assess data availability, provenance, quality, and suitability for analysis. 

• Build, validate, and maintain reproducible workflows for data extraction, transformation, cohort construction, data-quality checks, and analysis-ready datasets. 

• Develop, validate, and document repeatable workflows for structured clinical data and unstructured notes, including clinical concept extraction and natural language processing where appropriate. 

• Support real-world evidence and post-market analyses, including trend assessments, subgroup analyses, evidence synthesis, and other analyses needed to evaluate device safety and performance. 

Biostatistical Support for Preclinical and Clinical Studies 

• Provide biostatistical support for preclinical and clinical studies including but not limited to input on protocols, study design, endpoints, analysis populations, sample size or precision considerations, and data-collection strategies. 

• Support development and maintenance of Statistical Analysis Plans, programming specifications, analysis datasets, table shells, and other analysis documentation. 

• Review study data and data structures for quality, completeness, consistency, and alignment with planned analyses; identify issues and help coordinate their resolution.

• Interpret and communicate results in the context of study objectives, limitations, and clinical or scientific relevance, and contribute to study reports, clinical evaluation materials, regulatory submissions, publications, abstracts, posters, and presentations. 

Data Workflows, Documentation, and Quality 

• Build and implement data workflows in coordination with internal IT and external data partners, following established processes for access, secure storage, audit logging, permitted use, onboarding, and data transfer. 

• Maintain clear documentation of data definitions, source systems, data transformations, statistical methods, assumptions, quality checks, and results so that work can be reviewed and reproduced. 

• Apply appropriate quality-control practices to datasets, analyses, programs, and outputs, escalating material issues and risks in a timely manner. 

• Contribute to the development and continuous improvement of standards, templates, workflows, and best practices for data science and biostatistical analyses. 

Cross-Functional Collaboration and Communication 

• Translate complex statistical and data-science concepts into clear, actionable explanations for technical and nontechnical stakeholders. 

• Present analytical findings, assumptions, limitations, and recommendations to project teams and other internal audiences. 

• Contribute to a collaborative, accountable, and scientifically rigorous team environment.
