Job description

We are seeking an experienced, highly quantitative scientist to lead bioanalytical strategy and quality control across a diverse portfolio of peptide, protein, and small molecule therapeutics. This individual will define analytical approaches, oversee external CROs, and ensure that all data generated are accurate, reproducible, and decision-grade.

This role is ideal for someone who combines deep knowledge of bioanalytical methods with a strong QC mindset and the ability to diagnose and resolve complex analytical challenges across multiple assay platforms.

• PhD in Analytical Chemistry, Pharmaceutical Sciences, Biochemistry, or related field
• 8–15+ years of relevant experience in biotech, pharma, or CRO environments
• Demonstrated expertise in bioanalytical method development, validation, and data interpretation within a quality management system (i.e. GLP / GMP)
• Strong understanding of both:
• Instrumental analysis as applied to drug substance drug product characterization
• Experience overseeing and critically evaluating CRO-generated data
• Working knowledge of GLP / GMP analysis and regulatory expectations (e.g., ICH Q2(R2))
• Solid grounding in chemical kinetics and interpretation of concentration–time rate data

Preferred Qualifications

• Experience in the development, qualification, and transfer of stability-indicating analytical methods, execution of forced degradation studies, and support of stability programs.
• Experience across multiple molecular modalities (polymers, peptides, proteins, and, small molecules)
• Background in analytical development or QC for regulated products
• Experience supporting IND-enabling and early/late stage GMP method validation studies for clinical programs
• Familiarity with complex or long-acting drug delivery systems

• Ownanalytical strategyand method validation
  • Define fit-for-purpose analytical approaches for drug substance / drug product, and mechanistic studies
  • Select appropriate assay platforms (RP-HPLC/UPLC and SEC, LC-MS, colorimetry, pH, viscosity, osmolarity, endotoxin, bioactivity, and other common USP methods.)
  • Validate methods that define our products critical quality attributes.

• Lead CRO oversight
  • Design and manage outsourced bioanalytical studies
  • Critically review assay development, validation, and sample analysis
  • Identify deficiencies in methods, data quality, or interpretation and drive resolution

• Ensure quantitative rigor and data integrity
  • Evaluate instrument calibration models, LLOQ, accuracy/precision, and assay robustness
  • Detect and troubleshoot issues such as matrix effects, instability, adsorption, and assay interference
  • Establish internal standards for data quality across programs

• Apply QC and regulatory principles
  • Ensure methods and datasets meet GLP and regulatory expectations (e.g., ICH Q2(R2))
  • Contribute to analytical sections of IND-enabling packages and regulatory filings
  • Implement quality systems and documentation standards where needed
  • Support cross-functional decision making
    • Work closely with CMC, pharmacology, and clinical teams to interpret data correctly
    • Provide clear recommendations based on quantitative evidence
    • Write reports that enable cross-functional understanding of methods and results.

• Operate across modalities
  • Apply consistent analytical thinking across polymers, peptides, biologics, and small molecules
  • Ensure comparability and continuity of data across platforms and studies
