Senior Manager, Stability Strategy

Who We Are
BioMarin is a leading rare disease biotechnology company focused on genetically defined conditions.
Guided by our purpose to develop medicines that make a profound impact on people’s lives, our global teams have delivered a portfolio of therapies since our founding in 1997. Our revolutionary treatments for conditions like achondroplasia (the most common form of dwarfism), PKU (phenylketonuria), CLN2, a form of Batten disease, and a number of forms of MPS (mucopolysaccharidosis) offer new possibilities for patients and families who previously had few, if any, available options. More recently, with the close of the Amicus acquisition, our portfolio has expanded to include therapies for Fabry disease and Pompe disease, expanding our ability to reach more people living with rare genetic conditions.
Our success comes from our unwavering commitment to excellence, our deep understanding of patient needs, our scientific expertise, and our world-class manufacturing capabilities. At the heart of BioMarin is a dedicated team of the brightest minds in the industry working together to deliver innovative therapies to patients and families around the world.

SUMMARY
The Senior Manager, Stability Strategy is a senior individual contributor responsible for defining and owning stability strategies for assigned products across the product lifecycle (development through commercialization). This role operates as a product-aligned stability subject matter expert and is expected to independently design, justify, and defend stability strategies under conditions of complexity and ambiguity.
The ideal candidate brings extensive experience in stability within the pharmaceutical or biotechnology industry, with the ability to operate in a multi-modality environment and lead complex investigations and cross-functional initiatives.
RESPONSIBILITIES
Product Stability Program Execution
• Serve as primary owner of stability strategy for assigned products across development and commercial stages.
• Design and maintain stability programs including choice of study conditions (ICH long term, intermediate, accelerated, stress), testing strategies, and bracketing and matrixing approaches.
• Independently define and defend strategies for complex scenarios including accelerated development approaches, reduced testing design (bracketing/matrixing), SKU coverage and bridging strategies.
• Ensure phase-appropriate alignment of stability strategies with product knowledge, supply considerations, and regulatory expectations.
• Lead stability strategy support for process changes and comparability assessments, technology transfers, and lifecycle management activities, including post-approval changes.
• Make risk-based decisions in the absence of clear regulatory or industry precedent.
• Author and review stability reports and summaries for inclusion in INDs, BLAs, Annual Reports, and other regulatory submissions
• Lead investigations for significant deviations and quality events, including those at external testing laboratories, ensuring timely and compliant resolution
• Drive continuous improvement of processes to maintain compliance while supporting operational and commercial needs
• Author and review technical documentation, including protocols, reports, SOPs, test methods, and risk/impact assessments
• Initiate and own Quality Management System (QMS) records such as deviations, change controls, and CAPAs related to the stability program.
Data Management and Analysis
• Analyze and interpret stability data to establish and justify expiry and retest periods, assess degradation pathways and product risk, support storage and shipping condition recommendations, including allowable excursions.
• Identify emerging trends and risks and proactively drive mitigation strategies.
• Support the generation, maintenance, and reporting of stability data for clinical and commercial programs, including drug substance, drug product, and critical intermediates.
• Oversee the collection and analysis of stability data and interpreting results to identify potential issues or trends; this includes accessing data from LIMS or CofAs and performing data analysis in data trending software (such as JMP) to generate and support conclusions in technical documentation.
• Perform statistical analysis to provide shelf-life projections, support proposals for end-of-shelf-life specifications and monitor the performance of stability batches using statistical analysis to detect potential adverse trends which may need to be investigated.
• Partner with the Product Quality Leaders (PQLs) to perform the statistical calculations needed to set acceptance criteria for product comparability
CMC Regulatory Submission Support
• Author and review stability sections for global regulatory submissions (e.g. IND/CTA, NDA/BLA, MAA, post-approval changes).
• Author annual report sections with stability summaries and data for regulatory submissions including but not limited to the US Annual Report, Canadian Yearly Biological Product report, and Brazil Annual Product Report
• Support responses to health authority questions and information requests
• Ensure all strategies align with ICH guidelines and applicable global regulatory requirements.
Cross-Functional Alignment
• Coordinate with other departments (such as External Quality, QC, Analytical, PQL) to ensure that stability testing is integrated in the product development process.
• Translate complex stability considerations into clear, actionable recommendations
• Drive alignment on strategy through scientific credibility and influence.
• Coordinate with other departments to ensure the stability strategy is properly executed, including placement of annual commitment batches into the stability program according to regulatory commitments.
EXPERIENCE
Required Skills:
• 10+ years of experience within the Biotechnology, Pharmaceutical, or other highly regulated industry.
• Demonstrated experience defining and managing stability programs across development and commercial phases of the product lifecycle.
• Strong experience interpreting stability data to support expiry and/or retest decisions.
•
