What You Will Contribute To Altos

We are seeking a highly motivated and hands-on Scientist to join the Drug Product Process Development team within Technical Operations at the Institute of Medicine. This is a predominantly bench-based role; the successful candidate will independently design and execute experiments daily, advancing mRNA-LNP,AAV and Protein-based therapeutic programs. Working in a dynamic and cross-functional environment, this scientist will perform formulation and drug product process development, and provide technical support for outsourced GMP manufacturing activities.

Responsibilities

• Perform hands-on formulation and drug product process development for mRNA-LNP therapeutics, with additional involvement in AAV gene therapy and protein drug product development.
• Design and execute experiments to develop stable and effective drug product formulations, including excipient selection, concentration optimization, and compatibility studies; build internal drug product process development capabilities and produce materials to supply non-clinical studies.
• Develop and scale up drug product manufacturing processes, considering critical process parameters (CPPs) and critical quality attributes (CQAs); apply statistical analysis and experimental design to optimize process parameters and maximize product yield and quality.
• Conduct stability testing to assess the long-term integrity of drug products under various storage conditions and identify potential degradation pathways.
• Collaborate with CDMOs to optimize and improve drug product manufacturing processes, support scale-up, and contribute to in-process control strategies; provide technical support for GMP manufacturing activities including document review.
• Maintain accurate laboratory records, document experimental protocols and results, and contribute to development reports and regulatory submissions.
• Stay current with industry trends, emerging technologies, and regulatory guidelines to support continuous process improvement and compliance.
• Actively contribute to a team culture of continuous improvement, ownership, professional growth, and inclusion.
