The Opportunity

The Senior Director, Pharmacometrics will provide strategic and scientific leadership for pharmacometric activities supporting Amylyx’s clinical development portfolio. This leader will develop and execute model-informed drug development strategies across programs and stages of development, using quantitative approaches to inform dose selection, clinical trial design, regulatory strategy, and benefit-risk assessment.

Serving as a key scientific partner to Clinical Pharmacology, Clinical Development, Biostatistics, Regulatory Affairs, Translational Medicine, and other cross-functional teams, this individual will translate complex quantitative analyses into clear, actionable recommendations for program teams and senior leadership. The role requires both strategic leadership and hands-on technical depth as programs advance toward regulatory submissions and commercialization.

Responsibilities

• Develop and lead pharmacometrics strategies across assigned clinical development programs, aligning model-informed drug development plans with clinical and regulatory objectives.
• Lead population pharmacokinetic(PopPK), PK/PD, exposure-response, disease progression, and other quantitative modeling and simulation activities to inform dose and regimen selection, trial design, patient population selection, and interpretation of clinical data.
• Provide quantitative input into clinical development plans, protocols, statistical analysis plans, integrated development plans, regulatory strategies, and key program decisions throughout the development lifecycle.
• Support regulatory submissions and interactions, including INDs, NDAs/BLAs, briefing documents, health authority responses, and pharmacometrics or clinical pharmacology components of submission documents.
• Integrate clinical pharmacology, biomarker, efficacy, safety, and other relevant data into modeling strategies that support development recommendations and benefit-risk assessment.
• Partner cross-functionally with Clinical Pharmacology, Clinical Development, Biostatistics, Data Science, Clinical Operations, Regulatory Affairs, Medical Affairs, CMC, and other functions, communicating complex results clearly to multidisciplinary teams and senior leadership.
• Provide scientific oversight of external pharmacometrics consultants, CROs, and vendors, including scopes of work, analysis review, deliverable assessment, and adherence to scientific, regulatory, and quality standards.
• Advance functional capabilities, processes, standards, and best practices; mentor colleagues, identify emerging quantitative methodologies, and potentially build and lead internal pharmacometrics capabilities as the organization grows.

Required Qualifications

• PhD, PharmD, MD, or equivalent advanced degree in Pharmacometrics, Clinical Pharmacology, Pharmacokinetics, Pharmaceutical Sciences, Biomedical Engineering, Statistics, or a related quantitative discipline.
• Typically 12–15+ years of relevant biotechnology or pharmaceutical industry experience, including substantial experience in pharmacometrics and model-informed drug development.
• Demonstrated expertise in population PK(PopPK), PK/PD, exposure-response, modeling and simulation, and quantitative clinical pharmacology across multiple phases of clinical development.
• Experience developing quantitative strategies, independently executing or overseeing complex analyses, critically evaluating results, and translating findings into clear development recommendations.
• Demonstrated experience supporting regulatory submissions and preparing materials for, or interacting with, the FDA or other health authorities.
• Proficiency with commonly used pharmacometric modeling and simulation tools such as NONMEM, Monolix, R, Phoenix NLME, or comparable platforms.
• Strong scientific communication, presentation, collaboration, and influencing skills, including the ability to explain complex quantitative concepts to technical and non-technical audiences.
• Demonstrated ability to manage external consultants, CROs, and technical vendors while operating effectively in a dynamic, growing biotechnology organization.

Preferred Requirements

• Experience supporting late-stage clinical development and regulatory submissions.
• Knowledge of evolving regulatory expectations and guidance related to population pharmacokinetics, exposure-response analyses, and model-informed drug development.
• Experience building pharmacometrics capabilities, mentoring technical colleagues, or leading a pharmacometrics function.
