- Help design and implement automated downstream workflows for high-throughput purification of research-grade mRNA
- Support execution of research-grade mRNA production runs for discovery and preclinical studies, as needed
- Support process scale-up from bench to pilot scale, as needed
- Evaluate emerging purification technologies and chromatography resins
Support tech transfer and CDMO manufacturing- Perform tech transfer of downstream processes to CDMOs
- Act as person in plant during CDMO manufacturing runs
- Support process troubleshooting and deviation investigations at CDMOs
Documentation and collaboration- Maintain organized experimental records in Electronic Lab Notebooks
- Author development SOPs and technical development reports
- Present experiment results at team meetings
Requirements- Ph.D. in analytical chemistry, biochemistry, molecular biology, chemical engineering, or a related field with 0-3 years of relevant industry experience, or an M.S. with 5+ years or B.S. with 7+ years of relevant industry experience
