• Evaluate and implement alternative technologies to establish robust, reproducible, and scalable next-generation manufacturing processes.
• Collaborate with R&D teams to address process challenges and understand product quality variability across processes.
• Independently design and execute process development studies using Design of Experiment (DOE) and apply statistically sound methods for study design and data analysis.
• Analyze data, communicate results, and author detailed technical reports.
• Present key findings to internal teams, external partners, and major stakeholders.
• Author and review technical documentation, including standard operating procedures and batch records.
• Lead technology transfer to both internal and external manufacturing teams and provide training for GMP production.
• Identify and resolve manufacturing issues in coordination with the CMC team, proactively addressing potential challenges.
• Prioritize and manage studies to focus resources on the most impactful activities.
• Lead and mentor a small team of scientists and associates, providing guidance and leadership to junior members.
• Present research results at scientific conferences, author reports, and contribute to regulatory filings.
• Work cross-functionally with other teams to meet project milestones while maintaining adherence to timelines.

Requirements, Knowledge, Skills and Abilities
