The Director will be responsible for establishing and executing the analytical development strategy across starting materials, drug substance and drug product. This individual will play a critical role in preparing the company for clinical development and establishing an analytical control strategy that can evolve with the programs through later-stage development. The ideal candidate is a scientifically rigorous, hands-on analytical development leader who has experience taking analytical methods from early development through method qualification/validation and GMP implementation. Experience with peptides, PEGylated molecules, other complex biologics/bioconjugates as well as particulates is highly desirable. Demonstrated ability to grow an Analytical Development organization as well as manage CRO/CDMOs is a plus. This is an important leadership role in a small, fast-moving organization. The successful candidate will be comfortable operating strategically while also diving into experimental details, troubleshooting challenging analytical problems, and working closely with internal teams and external CRO/CDMO partners. ## Responsibilities Analytical Development Strategy - Develop and execute the analytical development strategy supporting the company's pipeline from preclinical development through clinical development. - Define analytical requirements for starting materials, drug substance and drug product, including release, stability, characterization, and in-process testing. - Establish appropriate analytical control strategies aligned with product and process understanding and the stage of development. - Provide analytical development leadership for CMC activities supporting regulatory submissions, including the IND and subsequent clinical-stage filings. - Identify analytical risks and develop appropriate mitigation strategies. Method Development, Qualification & Validation - Lead development, optimization, qualification, and validation of analytical methods for complex pharmaceutical molecules. - Develop methods for attributes including identity, purity, impurities/degradants, potency, concentration, physical properties, and product-related variants. - Establish scientifically sound analytical procedures and acceptance criteria appropriate to the stage of development. - Design and oversee method validation studies in accordance with applicable ICH and regulatory expectations. - Develop analytical method lifecycle strategies, including transfer, qualification, validation, and ongoing monitoring. - Evaluate analytical methods for robustness, specificity, accuracy, precision, linearity, range, detection/quantitation limits, and other applicable performance characteristics. Peptide / PEG Analytical Development - Lead analytical characterization of peptide- and/or PEG-containing molecules, as applicable to the company's pipeline. - Develop strategies for characterization and quantitation of molecular heterogeneity, impurities, degradation products, aggregates, and other product-related species. - Experience with techniques such as HPLC/UPLC, LC-MS, SEC, ion exchange, peptide mapping, spectroscopy, and related chromatographic and mass spectrometric approaches is highly desirable. - Establish fit-for-purpose analytical approaches for complex molecules where conventional methods may require significant development or customization. - Experience with comparability testing for the 505(b)2 regulatory pathway is a plus. GMP & Clinical Readiness - Ensure analytical methods and supporting documentation are appropriate for GMP manufacturing and clinical supply. - Partner with Quality, CMC and Regulatory colleagues to establish analytical procedures, specifications, sampling plans, and stability programs. - Support analytical aspects of drug substance and drug product release and stability testing. - Provide analytical oversight of external testing laboratories, CROs, and CDMOs. - Review analytical data, reports, protocols, method validation packages, certificates of analysis, and other technical documentation. - Support investigations, out-of-specification/out-of-trend investigations, deviations, and analytical troubleshooting as needed. External Partner Management - Establish and manage relationships with analytical CROs, contract laboratories, and CDMOs. - Define analytical scopes of work, technical requirements, timelines, and deliverables. - Provide scientific oversight and critically evaluate externally generated data. - Ensure external analytical activities remain aligned with development timelines and regulatory requirements. Leadership & Cross-Functional Collaboration - Build and lead the company's analytical development capabilities as the organization grows. - Collaborate closely with CMC, Process Development, Manufacturing, Quality, Regulatory, Clinical, and Program Management functions. - Translate analytical data into clear scientific conclusions and development recommendations. - Represent Analytical Development in internal program reviews and external interactions with partners and regulatory agencies. - Contribute to the development of a high-performing, collaborative, and scientifically rigorous company culture. ## Qualifications - Ph.D. in Analytical Chemistry, Pharmaceutical Sciences, Biochemistry, Chemistry, or a related scientific discipline, or equivalent industry experience. - 10+ years of relevant pharmaceutical/biotechnology industry experience, with increasing responsibility in analytical development. - Demonstrated experience developing and implementing analytical methods for pharmaceutical products. - Strong experience with analytical method development, qualification, and validation. - Experience supporting CMC activities for clinical-stage programs and/or regulatory submissions. - Strong understanding of analytical characterization, specifications, stability, and analytical control strategies. - Experience working with GMP laboratories and external analytical testing organizations. - Demonstrated ability to independently interpret complex analytical data and make sound scientific decisions. - Excellent written and verbal communication skills. - Ability to work effectively in a small, entrepreneurial, cross-functional environment. ## Preferred - Experience with peptides, PEGylated molecules, bioconjugates, or other complex therapeutic modalities. - Experience with analytical characterization of chemically heterogeneous or structurally complex molecules. - Hands-on expertise with HPLC/UPLC, LC-MS, SEC, ion-exchange chromatography, peptide mapping, and related analytical technologies. - Experience developing analytical methods for both drug substance and drug product. - Experience authoring or reviewing analytical sections of INDs, IMPDs, or other regulatory submissions. - Experience transferring methods to GMP laboratories and/or CDMOs. - Experience establishing an analytical function within a small or growing biotechnology company. - Prior experience managing scientists or analytical development personnel. - Regulatory-minded — understands what makes analytical methods scientifically defensible and inspection-ready.
