The Position

Key Responsibilities

• Metabolite Profiling & Identification: Conduct in vitro (e.g. microsomes, hepatocytes, S9, lysosome) and in vivo (e.g. plasma, urine, feces, bile, tumor tissue) metabolite identification studies across various species.

• Mass Spectrometry Lead: Operate, troubleshoot, and maintain advanced LC-HRMS instrumentation (e.g., Orbitrap or Q-TOF).

• Structural Elucidation: Interpret complex MS/MS fragmentation patterns to propose accurate chemical structures for metabolites.

• Pathway Mapping: Propose biotransformation pathways and identify potential "soft spots" in chemical leads to guide medicinal chemistry efforts.

• Reactive Metabolite Screening: Design and execute glutathione (GSH) trapping assays to assess potential idiosyncratic toxicity risks.

• Regulatory & Reporting: Oversee and manage CRO partnerships to ensure the delivery of high-quality technical reports; provide expert MetID authorship and scientific review for IND/NDA regulatory filings.

• Cross-Functional Collaboration: Partner closely with Medicinal Chemistry, DMPK/PD Lead, and Clinical Pharmacology lead to communicate the impact of metabolic data on project strategy.

Qualifications & Skills

• Educational Background: Ph.D. in Analytical Chemistry, Biochemistry, or related, with 4+ years of experience; or an MS with 8+ years of dedicated industry experience in small molecules and/or ADC DMPK.

• Technical Expertise: Proven mastery of liquid chromatography and high-resolution mass spectrometry (HRMS) for structure elucidation.

• Biotransformation Expertise: Demonstrates a mastery of Phase I/II biotransformation pathways with the ability to translate in vitro metabolic data into predictive in vivo outcomes; experience navigating the unique MetID challenges of Antibody-Drug Conjugates (ADCs) is a significant plus.

• Soft Skills: Exceptional communication skills with the ability to "distill the essence" of complex data for stakeholders at all levels.
