Director, Translational Biology & Biomarkers

Translational Biomarker Strategy

• Own and execute clinical biomarker plans in alignment with program team goals and clinical function. - Design and execute Sail’s biomarker strategies to support a clinical-stage portfolio, including biomarker-driven clinical study design and incorporation of biomarker endpoints for decision-making in early-stage clinical trials. - Provide scientific and technical leadership for development, qualification, validation, and lifecycle management of PK, ADA, neutralizing antibody, cell-based potency, and pharmacodynamic assays. - Ensure assays are fit-for-purpose and aligned with regulatory expectations (GLP/GCLP), in close collaboration with Preclinical Pharmacology, Regulatory, Clinical, and Quality teams. - Oversee internal and external assay development activities, including CRO and central laboratory management, ensuring scientific rigor, data integrity, and timeline adherence. - Review and approve assay validation plans, reports, and work orders from analytical laboratories. - Analyze and interpret biomarker and immunogenicity data and communicate biological and clinical implications to support program decisions. - Define data transfer specifications in collaboration with translational science, data management, and data science teams to ensure high-quality clinical biomarker datasets. - Represent the Biomarker function at internal and external meetings and provide project status updates related to biomarker deliverables. Cross-Functional & Operational Leadership

• Partner with Clinical Operations to ensure appropriate collection, shipment, and analysis of clinical samples. - Coordinate with internal and external stakeholders (CROs, central labs, clinical sites) to address specimen-related and assay-related issues. - Manage timelines, budgets, and external partnerships for bioanalytical and biomarker programs. - Advise senior and matrixed leaders on bioanalytical risk, strategy, and development trade-offs. Qualifications

• PhD or MD in Immunology, Cell Biology, or related scientific discipline with 10+ years of experience in a Biotech or Pharmaceutical setting; or equivalent combination of education and experience. - Demonstrated expertise in bioassay development, qualification, validation, and regulatory submission support. - Deep knowledge of PK, immunogenicity, cell-based functional assays, potency assays, and biomarker assay development. - Strong understanding of drug development, regulatory processes, and clinical development, including GLP/GCLP bioanalytical expectations. - Proven experience building and leading scientific teams in a growing biotech environment. - Strong strategic thinking, sound judgment, and ability to operate effectively in a fast-paced, matrixed organization. - Track record of advancing multiple programs simultaneously and implementing creative, solution-oriented strategies. - Excellent interpersonal, communication, and organizational skills.
