      • Pharmacokinetics (PK)
      • Immunogenicity (ADA)
      • Biomarker detection (exploratory and translational)
    • Perform non-clinical sample analysis to support discovery and development programs.
    • Troubleshoot assay performance issues, implement improvements, and document method changes.
    • Conduct critical reagent labeling (e.g., biotinylation, fluorophore conjugation) and manage reagent inventory.
    • Maintain accurate and detailed records in electronic lab notebooks (ELNs) and ensure compliance with internal quality systems.
    • Analyze and interpret data; present findings to project teams.
  • Vendor Management (Oversight)
    • Coordinate and oversee method development, transfer, and validation activities at external bioanalytical labs.
    • Review protocols, reports, and data from CROs to ensure quality and compliance with regulatory expectations.
    • Serve as a technical point of contact for troubleshooting and assay-related discussions with external partners.
  • Cross-Functional Collaboration
    • Work closely with Research, Nonclinical Development, Translational Sciences, and Clinical Development teams to align bioanalytical strategies with program goals.

Qualifications

Required:

  • Degree in Biochemistry, Molecular Biology, Pharmacology, or related field:
    • BS + 8 years, MS + 5 years, or PhD + 2 years of relevant hands-on industry experience in bioanalytical or immunoassay settings.
  • Strong experience in ligand binding assays for PK, ADA, and biomarker applications.
  • Proficiency with MSD (electrochemiluminescence) and ELISA platforms.
  • Demonstrated ability to troubleshoot and optimize assay performance.
  • Experience with non-clinical sample matrices (e.g., rodent, NHP plasma or serum).
  • Expertise in reagent labeling and qualification (biotinylation, conjugation).
  • Excellent documentation and organizational skills.

Preferred:

  • Experience managing assays at external CROs is a plus
  • Experience with automated immunoassay platforms (e.g., Gyrolab) is a plus
  • Knowledge of regulatory bioanalytical guidelines (FDA, EMA).
  • Familiarity with GLP or GxP-adjacent environments.
