• Review release and stability test results to ensure accuracy, completeness, and compliance with specifications, procedures, GMP requirements, and overall data integrity
• Execute and support registration stability programs, including protocol implementation, sample management, and data evaluation across timepoints
• Apply scientific understanding of degradation pathways to interpret analytical data for trending purposes, and support investigations (OOS, OOT, deviations) and CAPA analysis
• Maintain and ensure integrity of data within LIMS and stability databases, ensuring accurate data entry, traceability, and audit readiness
• Conduct data integrity reviews and assessments in alignment with ALCOA+ principles, identifying gaps and supporting remediation actions as needed
• Author and review analytical reports and regulatory documentation, including sections supporting stability, specifications, and method performance
• Design and execute analytical experiments to support method lifecycle activities, including development, qualification/validation, transfer, or troubleshooting
• Collaborate with cross-functional teams to communicate data insights, support investigations, and contribute to project milestones and regulatory submissions
• Experience with data analysis tools (e.g., Excel advanced functions, JMP, or statistical software) for trending and visualization
• Working knowledge of ICH guidelines and regulatory expectations for analytical methods and stability programs
• Evaluate temperature excursions for stability and release samples, assessing potential impact on product quality using scientific judgment, stability data, and relevant regulatory/technical guidance

Required Qualifications:

• 8+ years of hands‑on experience with analytical techniques (e.g., HPLC/UHPLC, LC‑MS, GC, compendial tests) supporting release and/or stability testing
• Experience trending and interpreting stability and QC data, with a working understanding of degradation pathways and stability‑indicating methods
• Proficiency with LIMS and laboratory data systems, along with a strong understanding of data integrity principles (ALCOA+) and regulatory expectations
• Strong technical writing and communication skills, including experience reviewing analytical data and contributing to reports or regulatory documentation
• Demonstrated collaboration and problem‑solving skills, with the ability to manage multiple priorities in a fast‑paced, quality‑focused environment

Preferred Qualifications:

• Experience supporting regulatory submissions (e.g., IND, NDA, BLA) with analytical or stability sections
• Familiarity with stability program design and lifecycle management in a pharmaceutical or biotechnology setting
• Experience participating in or supporting regulatory inspections and audits
• Exposure to method development, qualification/validation, or transfer activities within Analytical Development or QC
• Advanced degree preferred

Education:

• Bachelor’s, Master’s, or Ph.D. in Analytical Chemistry, Biochemistry, Pharmaceutical Sciences, or a related discipline within a GMP‑regulated environment

Salary Range: $106,000 — $130,000 USD
