The Role:

SAIL Biomedicines is seeking a Director / Senior Director of DMPK & Clinical Pharmacology to lead and shape DMPK strategy across discovery, preclinical development, and early clinical translation. This role will be a key cross-functional partner responsible for defining and executing preclinical DMPK strategies while also supporting clinical pharmacology planning and execution as programs transition toward first-in-human (FIH) studies.

We are seeking a strategic and scientifically rigorous leader with deep expertise in preclinical DMPK, including semi-quantitative and traditional DMPK modeling approaches, and with additional experience in clinical pharmacology considered a strong plus to support upcoming clinical development needs.

Responsibilities:

• Develop and implement preclinical DMPK & clinical pharmacology strategies that advance SAIL’s programs through IND-enabling activities and into early clinical development.
• Serve as the DMPK subject matter expert on cross-functional program teams, providing scientific leadership across ADME, distribution, metabolism, PK, PK/PD relationships, and dose-exposure-response understanding.
• Lead semi-quantitative, mechanistic, and traditional DMPK modeling efforts, including human dose projection, PK/PD interpretation, and translational assessments to inform candidate selection and development decisions
• Oversee the design, execution, and interpretation of preclinical DMPK studies, ensuring scientific rigor, data quality, and alignment with program objectives.
• Lead and manage execution of all IND-enabling DMPK activities, including PK, PK/PD, bioanalytical strategy, and modeling and simulation efforts to support FIH dose selection.
• Draft and contribute to key regulatory documents such as IND summaries and reports, Investigator Brochures, and submission materials. Serve as a primary contact for resolving pharmacology-related regulatory questions and preparing response documents.
• Support clinical pharmacology strategy and execution, including contribution to clinical dose rationale, exposure-response assessments, and early clinical study design as programs enter the clinic.
• Manage external vendors and CROs supporting DMPK and modeling activities, ensuring delivery within scope, timelines, and budget

Required Qualifications:

• Bachelor’s degree with 15+ years of experience within the pharmaceutical/biotechnology industry, or a PhD/PharmD with 10+ years of experience within the pharmaceutical/biotechnology industry

Preferred Qualifications:

• Proven success leading preclinical DMPK programs that progressed to IND and early clinical development
• Hands-on experience with semi-quantitative and traditional DMPK modeling approaches
• Clinical pharmacology experience (e.g., FIH dose selection, exposure-response analysis, clinical PK interpretation) preferred, but not required
• Experience supporting regulatory interactions related to DMPK and clinical pharmacology
• Self-motivated with strong initiative and deadline-driven execution
• Ability to identify risks, propose mitigation strategies, and influence program direction
• Meticulous attention to detail and effective prioritization under tight timelines
• Strong presenter, able to communicate clearly across all organizational levels
• Capable of setting objectives, adjusting priorities, and providing actionable feedback
• Sound judgment aligned with broader R&D strategy context
• Diplomatic and influential communicator
• Excellent interpersonal, written, verbal, analytical, and organizational abilities
• Effective manager of external consultants and vendors
• Recognized thought leader to shape cross functional scientific and strategic decisions
