In this role, the candidate will lead complex experimental studies, including the design of formulation screening strategies, analytical testing, and physicochemical characterization of drug products; support investigations; and contribute to process optimization and technical problem-solving.

Essential Functions:

• Support and execute the manufacture of complex drug products to support formulation development, analytical development, animal immunogenicity studies, and process development.
• With guidance, design, plan, and independently perform complex experiments, including troubleshooting and optimization of formulation processes.
• Analyze and interpret experimental data; clearly communicate findings through presentations in working group meetings and contributions to technical reports and presentations.
• Analyze samples with biochemical, biophysical and particle characterization techniques, interpret results, and communicate conclusions to the broader team.
• Prepare buffers, solutions, and reagents to support formulation and analytical activities, ensuring accuracy and consistency.
• Maintain scientific rigor and ensure detailed, accurate documentation of all experiments conducted.
• Support and enhance laboratory organization, including bench management, inventory control, and compliance with safety and regulatory standards.
• Ensure accurate, thorough, and timely documentation of all experimental work in electronic lab notebooks.
• This position reports into the Formulation Development function and is part of the broader Process Development and Manufacturing group.
• This position will collaborate with cross-functional groups and the ability to work effectively in a collaborative environment is essential.
• Demonstrate agility in both scientific thinking and practical execution; a proactive, solution-oriented mindset is strongly encouraged.
• This is a lab-based position and requires the ability to stand or sit for extended periods as well as work in biosafety cabinets.

Requirements: 

• BS degree in Chemistry, Biochemistry, or related field with minimum 5 years of relevant industry experience, or MS degree with minimum 3 years of relevant industry experience. Experience in vaccine formulation development is a plus.
• Strong hands-on experience in buffer preparation, formulation development, and laboratory techniques.
• Demonstrated ability to independently design and execute experiments and troubleshoot technical challenges.
• Proficiency in maintaining detailed and accurate records; experience with electronic lab notebooks (ELN) is required.
• Experience interpreting complex data sets with data analysis tools (e.g., GraphPad Prism, JMP) and a solid understanding of statistical analysis is preferred.
• Strong organizational skills with attention to detail in pipetting, sample preparation, and data recording.
• Proficiency in Microsoft Office (Word, Excel, PowerPoint).
• Proven ability to work effectively in a cross-functional, collaborative environment across multiple projects.
• Strong interpersonal, written, and verbal communication skills.
• Demonstrated initiative, scientific curiosity, and the ability to contribute strategically within a fast-paced team.
