Qualifications

• A degree in Molecular Biology, Biochemistry, Engineering, or other STEM-related discipline.
• A Bachelor's degree with 8-10 years of relevant laboratory experience, or a Master's degree with 3-5 years of relevant laboratory experience.
• Experience with process development and characterization, technology transfer and training, validation, and/or commercial manufacturing support.
• Knowledge of process optimization and scale-up from lab formulations to factory production is highly desirable.
• Strong technical problem-solving skills with the ability to design experiments, analyze data, and develop practical solutions to complex challenges.
• Excellent written and verbal communication skills, including technical documentation and scientific presentations.
• Familiarity with standard protein characterization techniques (e.g., SDS-PAGE, analytical SEC, IEF).
• Proven ability to work effectively in cross-functional teams.
• Proficiency in one or more protein conjugation chemistries is highly desirable.
• Demonstrated expertise in mammalian biologics process development is highly desirable.
• Sound judgment in assessing technical risks and opportunities.
• Ability to adapt to changes in timelines, priorities, and other unexpected circumstances.
• Strong organizational skills and ability to plan work across teams.
• Familiarity with risk assessment, FMEAs, and CEAs is highly desirable.
• Experience with raw material characterization and specification setting is highly desirable.
• Scientific curiosity and dedication to continuously learn and improve.

Responsibilities

• You will perform experiments spanning organic chemistry, biochemistry, bioprocess, and material science to improve new liquid phase and solid phase reagents, their assay performance, stability, and manufacturability.
• You will use design of experiments (DOE) methodology to guide statistically rigorous experiments that analytically and functionally characterize a wide variety of conjugates (biological and surface based).
• You will contribute throughout the product development lifecycle, including feasibility assessment, process development, verification and validation activities, and investigations.
• You will collaborate with teams across R&D and Operations from the conceptual design of reagents through development and transfer of processes into a manufacturing environment.
• You will share process and reagent knowledge with downstream manufacturing teams.
