Job Description

We are seeking an accomplished and highly motivated Senior Principal Scientist (Sr. Director equivalent) to serve as an Immunology Biomarker Lead within Translational Clinical Biomarkers. This role provides strategic and scientific leadership in the design, execution, analysis, and communication of clinical biomarker strategies across our immune-mediated therapeutic portfolio from discovery to pivotal clinical studies.

The successful candidate will drive decision-centric biomarker strategies that connect drug mechanism, disease biology, precision medicine, pharmacodynamics, dose decisions, and clinical endpoints, directly informing program- and portfolio-level decisions across the development lifecycle.

This role requires strong leadership of multi-disciplinary team efforts through deep scientific expertise, structured decision-making, sophisticated data analysis & interpretation; and cross-functional collaboration, aligning stakeholders in a fast-paced, matrixed environment.

Primary Responsibilities:

Strategic Leadership & Program Impact:

• Lead and shape integrated biomarker strategies across discovery, early- and late-stage clinical programs, ensuring clear hypotheses, fit-for-purpose endpoints, and explicit linkage to key development decisions, in close collaboration with cross-functional leaders, particularly in Discovery, Late-Stage Clinical Development and across Translational Medicine

• Serve as the biomarker strategy lead within cross-functional program teams and represent multi-disciplinary team(s) in governance forums, ensuring biomarker strategies to address mission-critical questions for both forward and reverse translation

• Inform portfolio strategy by advancing biomarker-driven insights that inform target validation, patient selection, and go/no-go decisions

• Translate disease biology and therapeutic mechanism of action into clinically actionable biomarker strategies addressing critical program questions, e.g. proof of biology, pharmacodynamic effects, precision medicine and surrogate endpoints for efficacy.

• Drive selection and application of innovative biomarker approaches, aligned with biological rationale and clinical utility

Cross-functional Leadership & Alignment:

• Lead biomarker sub-teams and related working groups, including clinical, discovery, translational, regulatory, bio-stats, and data sciences

• Collaborate effectively across disciplines to integrate scientific perspectives into cohesive strategies

• Provide scientific leadership to enable hypothesis-driven, decision-focused biomarker strategies

• Grow and develop team members, including mentorship of direct report(s) and other scientists in the department, acting as a role model and culture driver

Data Interpretation & Communication:

• Champion biomarker analysis plans and provide critical scientific input to the interpretation of complex datasets to deliver scientifically rigorous and clinically meaningful conclusions

• Clearly articulate insights to internal stakeholders, governance bodies, and external scientific audiences

• Support external engagement, including publications, presentations, and KOL interactions, as appropriate
