- Oversee execution of stability studies at CMOs and contract testing laboratories
- Perform statistical analysis and trending of stability data using JMP
- Support determination of drug substance and drug product shelf life/retest period according to ICH guidelines
- Author and review stability protocols, reports, SOPs and regulatory documentation
- Develop stability strategies aligned with product development objectives, manufacturing plans, clinical supply requirements, and regulatory expectations
- Define appropriate storage conditions, testing intervals, analytical test panels, acceptance criteria, and study durations
- Author, review and revise stability protocols, interim and final stability reports, SOPS, technical memoranda, specifications, and related controlled documents
- Perform comprehensive review, trending, and statistical analysis of stability data to assess degradation rates, variability, lot-to-lot differences, and longitudinal trends
- Use JMP statistical software for regression analysis, graphical evaluation, shelf-life projections, retest period assessments, and other stability-related statistical evaluations
- Identify emerging trends, meaningful changes, OOT results, OOS results, atypical findings, and potential product-quality or clinical-supply risks
- Support establishment and justification of drug substance retest periods and drug product shelf life or expiration dating
- Participate in or lead stability-related investigations, deviations, CAPAs, change controls, and other applicable Quality System records
- Evaluate temperature excursions during product storage and transportation and assess potential product impact using available stability data
- Collaborate with Quality Assurance, Regulatory Affairs, Process Development, Supply Chain, Clinical Supply, and external partners
- Identify and implement opportunities to improve stability processes, statistical methods, documentation, and external-partner performance
- Independently manage multiple studies, priorities, external partners, and timelines in a remote working environment
Skills
- BS/BA degree in Chemistry, Biochemistry, Pharmaceutical Sciences, Biology or a related scientific discipline; or
- MS/MA degree in related scientific discipline; or
- PhD in a related scientific discipline
- An equivalent combination of education and directly relevant experience may be considered
- Approximately 11 or more years of relevant pharmaceutical or biotechnology industry experience with a BS/BA degree; or
- Approximately 9 or more years of relevant experience with an MS/MA degree; or
- Approximately 5 or more years of relevant experience with a PhD
- Extensive experience managing pharmaceutical or biotechnology stability programs in a regulated development environment
- Strong understanding of stability principles for biologics and/or complex therapeutic products, including degradation pathways, accelerated stability studies, shelf-life determination, and retest-period assignment
- Strong knowledge of ICH stability guidelines, particularly ICH Q1A, Q1E, and Q5C, as well as relevant FDA, EU, and global regulatory expectations
- Demonstrated proficiency with JMP statistical software, including regression modeling, stability trending, graphical analysis, variability assessment, and statistical evaluation supporting shelf-life and retest-period decisions
- Ability to critically evaluate longitudinal stability data and identify OOT results, emerging trends, and potential product-quality risks
- Experience overseeing stability activities performed by CMOs and contract testing laboratories
- Strong understanding of cGMP requirements and pharmaceutical Quality Systems, including OOS, OOT, deviations, CAPAs, and change controls
- Strong understanding of analytical methodologies commonly used to assess biologic drug substance and drug product stability
- Excellent technical writing skills, including experience preparing stability protocols, reports, SOPs, technical memoranda, and regulatory documentation
- Excellent written and verbal communication skills, with the ability to explain complex scientific and statistical findings clearly to technical and non-technical audiences
- Ability to work independently and effectively with geographically distributed teams and external partners
- Experience working in an FDA-regulated environment
- Experience supporting IND, BLA, or equivalent global regulatory submissions
- Experience developing stability strategies for late-stage clinical development and preparation for commercialization
- Experience evaluating temperature excursions and applying stability data to product-impact assessments
Benefits
- This is a fully remote position.
