POSITION SUMMARY
We are seeking a highly motivated and experienced Director of Analytical Development to lead the development, qualification, validation, and implementation of analytical methods supporting our preclinical and clinical-stage programs.
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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
