Principal Scientist, Translational Clinical Biomarkers

Job Description

We are seeking an accomplished and highly motivated Principal Scientist to provide strategic and scientific biomarker leadership across programs within the Cardiovascular & Metabolic and Infectious Diseases/Vaccines portfolios.

This role will lead the design, execution, analysis, and communication of translational and clinical biomarker strategies across programs spanning early through late clinical development.

The successful candidate will develop decision-centric biomarker strategies that integrate therapeutic mechanism, disease biology, pharmacodynamics, patient heterogeneity, dose and regimen selection, clinical endpoints, and opportunities for precision medicine. Biomarker plans should focus on generating high-value, interpretable evidence that informs program decisions rather than data generation alone.

Key Responsibilities

• Significant experience developing and executing translational or clinical biomarker strategies in drug or vaccine development.

• Scientific expertise relevant to one or more areas within cardiovascular disease, metabolic disease, infectious diseases, vaccines, immunology, or related disciplines.

• Demonstrated ability to translate scientific hypotheses into biomarker strategies that inform clinical development decisions.

• Strong understanding of the relationship between mechanism of action, disease biology, pharmacology, biomarkers, clinical endpoints, and development strategy.

• Ability to lead cross-functional scientific work in a matrixed environment and influence without direct authority.

• Strong analytical and problem-solving skills, including the ability to synthesize complex datasets into clear, decision-oriented conclusions.

• Ability to prioritize high-value, decision-enabling biomarker work and distinguish it from lower-priority exploratory activities.

• Excellent written and verbal communication skills and the ability to communicate scientific strategy to stakeholders.

• Working knowledge of biostatistics, bioinformatics, quantitative sciences, and multidimensional biomarker data analysis.

• Strategic mindset with a focus on scientific rigor, prioritization, scalability, and generation of actionable evidence.

Preferred Experience and Skills

• Experience supporting programs across multiple stages of clinical development.

• Experience with pharmacodynamic, predictive, prognostic, patient-stratification, or precision-medicine biomarker strategies.

• Experience in cardiovascular/metabolic drug development and/or infectious disease and vaccine development.

• Experience working across multiple programs or therapeutic areas.

• Experience mentoring or providing scientific direction to other scientists.
