Position Summary

We are seeking a highly accomplished leader to serve as Senior Director / Director of Bioanalysis and Biotransformation. This role will provide strategic direction and hands-on leadership for bioanalytical and biotransformation functions supporting both nonclinical and clinical drug development programs.

The successful candidate will lead the design, development, and execution of bioanalysis, pharmacokinetics/toxicokinetic (PK/TK), drug metabolism, and biomarker assay strategies across discovery and development. This individual will ensure scientific excellence, regulatory compliance, and operational efficiency while partnering closely with cross-functional teams to advance programs toward key milestones.

Key Responsibilities:

• Provide scientific, technical, and strategic leadership for bioanalysis and biotransformation in support of discovery, nonclinical and clinical development programs.
• Oversee the design, development, qualification, validation, and execution of bioanalytical, PK/TK, and biomarker assays in compliance with GLP/GCP standards and global regulatory expectations.
• Lead the interpretation and integration of bioanalytical and biotransformation data to inform pharmacokinetics, exposure–response, and human dose projections.
• Manage and mentor internal teams and oversee external CROs, ensuring high-quality execution, adherence to timelines, and budget accountability
• Ensure data integrity, high-quality documentation, and inspection of readiness for regulatory submissions, audits, and health authority inspections.
• Partner closely with cross-functional teams—including DMPK, Toxicology, Clinical Development, and Biology—to align bioanalytical strategies with program objectives and development milestones.
• Contribute to regulatory filings (e.g., IND, CTA, NDA/BLA) and support responses to health authority inquiries related to bioanalysis and biotransformation.
• Present scientific strategies, results, and data interpretation to cross-functional teams, senior leadership, and external stakeholders.
• Drive continuous improvement and innovation in assay platforms, analytical technologies, and operational processes.

Minimum Requirements:

• Ph.D. or equivalent degree in Biochemistry, Pharmacology, Analytical Chemistry, or related scientific discipline.
• 10+ years of industry experience in bioanalysis, with demonstrated impact across nonclinical and clinical drug development programs.
• Deep expertise in pharmacokinetic (PK), pharmacodynamic (PD), and biomarker assay development to support nonclinical and clinical studies, with a strong focus on clinical, translational, and precision biomarker applications.
• Proven ability to bridge nonclinical and clinical biomarker strategies, including fit-for-purpose assay validation, assay transfer, and integration of bioanalytical data to inform dose selection, safety, and efficacy decisions.
• Established people and matrix leadership experience, including managing internal teams and external CROs, and partnering effectively with cross-functional stakeholders.
• Strong working knowledge of GLP/GCP and global regulatory expectations, with direct experience supporting IND/CTA-enabling studies, clinical trials, and inspection-ready bioanalytical data packages.
• Experience supporting novel therapeutic modalities (e.g., oligonucleotides, biologics) and authoring or reviewing bioanalytical and biomarker sections of regulatory submissions.
• Excellent written and verbal communication skills, with the ability to clearly present complex nonclinical and clinical bioanalytical and biomarker data to project teams and senior leadership.
• Demonstrated ability to operate effectively in a fast-paced, resource-conscious environment, with a strong focus on data quality, compliance, and timely delivery.
• Working knowledge of, and/or hands-on experience in drug metabolism across discovery and development stages is a plus.
