The successful candidate will partner with discovery scientists, nonclinical toxicologists, clinical pharmacologists, biostatisticians, program teams, and external vendors to ensure bioanalytical strategies and execution meet scientific, regulatory, quality, and program requirements. This individual will serve as the bioanalytical functional lead on cross-functional program teams and contribute to vendor strategy, regulatory activities, and evaluation of external opportunities.

Responsibilities

• Lead LC-MS/MS bioanalytical strategy across discovery, preclinical, and clinical development, ensuring approaches are scientifically rigorous, phase appropriate, and aligned with program timelines and regulatory requirements.
• Serve as Amylyx's senior bioanalytical LCMS subject matter expert across cross-functional program teams, providing strategic guidance on bioanalytical and biomarker science, PK/PD testing, technical risks, timelines, and development decisions.
• Oversee outsourced bioanalytical assay development and execution, including method development, qualification, validation, sample analysis, data review, and associated documentation in accordance with applicable FDA, ICH, and quality expectations.
• Provide technical leadership across small molecule, peptide, and oligonucleotide bioanalysis; identify assay challenges, determine root causes, implement fit-for-purpose solutions, and oversee critical reagent lifecycle and method performance.
• Lead external bioanalytical vendor strategy and oversight, including vendor selection, study planning, technical governance, troubleshooting, performance management, and escalation to ensure timely, high-quality execution.
• Partner with discovery, toxicology, clinical pharmacology, biostatistics, clinical development, and regulatory colleagues to integrate bioanalytical data into study designs, development plans, program decisions, study reports, and regulatory strategies.
• Contribute bioanalytical expertise to protocols, regulatory submissions, reports, abstracts, posters, publications, health authority interactions, and presentations to senior leadership.
• Provide scientific and technical expertise in evaluating external assets and potential in-licensing opportunities, including bioanalytical strategy, data quality, development risks, and capability requirements.

Required Qualifications

• Ph.D. in biology, chemistry, analytical chemistry, pharmaceutical sciences, or a related scientific discipline with at least 10 years of relevant scientific and technical experience, or an M.S. with at least 12 years of relevant experience, in pharmaceutical, biotechnology, or CRO environments.
• Significant experience developing and leading LC-MS/MS bioanalytical programs spanning preclinical lead nomination, IND-enabling development, and clinical Phase 1-3 programs.
• Demonstrated technical expertise in bioanalytical method development, qualification, validation, and sample analysis for small molecules, antisense oligonucleotides, and peptides, with expert-level capability in at least two of these modalities.
• Expert knowledge of bioanalytical regulatory requirements and guidance, including ICH M10 Bioanalytical Method Validation, and the ability to apply phase-appropriate regulatory rigor throughout drug development.
• Extensive experience overseeing outsourced bioanalytical work, including vendor management, technical issue resolution, study execution, data review, and documentation.
• Demonstrated experience contributing to regulatory documents and supporting health authority interactions, with the ability to translate complex bioanalytical science into clear recommendations.
• Strong scientific leadership, communication, collaboration, and influencing skills, including success working across disciplines in a fast-paced biotechnology environment.
• Ability to operate independently, manage multiple programs and external partners, adapt to evolving priorities, and travel up to 20% for vendor site visits, scientific collaboration, conferences, and other business needs.

Preferred Qualifications

• Experience in a biotechnology environment, particularly within a highly outsourced or virtual development model.
• Familiarity with complementary bioanalytical platforms such as RT-qPCR, ELISA, immunogenicity/ADA, or other large-molecule bioanalytical methods.
• Experience with CAPA, GxP-regulated bioanalysis, critical reagent lifecycle management, and due diligence of external assets.
