About the role
We are seeking an experienced Pathology Research Scientist to join us on a part-time, contractor basis . This individual will provide subject-matter expertise across biomarker discovery, diagnostic development, and computational pathology initiatives, supporting programs spanning translational research through clinical development.
The role requires deep expertise in surgical pathology, digital pathology, and tissue-based assays, and close collaboration with internal and client-facing teams in biomarkers, histotechnology/platform science, data science, and AI/ML. The Pathology Research Scientist will help ensure scientific rigor, clinical relevance, and regulatory-appropriate practices across multiple drug development and diagnostic programs.
The role will be fully remote, however preferred applicants are based on the US East Coast, Western Europe, or in the Asia-Pacific Region.
What you'll do
Serve as a pathology subject-matter expert (SME) for biomarker and diagnostic programs, including companion diagnostics, molecular pathology, digital pathology, and associated data science services .
Provide scientific guidance through critical literature review and synthesis of primary source data , including peer-reviewed publications, disease staging and grading systems, and established pathology reference standards.
Support computational pathology and AI/ML initiatives by translating clinical and histopathologic knowledge into actionable guidance for model design, training, validation, and interpretation .
Define disease- and indication-specific annotation guidelines , including relevant tissue compartments, cellular features, morphologic patterns, and common technical artifacts.
Perform or review digital slide annotations using validated platforms; provide peer review, quality control, and written validation of human- and algorithm-generated annotations in accordance with project requirements.
Support computational pathology and ML/AI teams through the translation of clinical and histopathologic knowledge into actionable guidance for model development, validation, and deployment.
