Job Summary Kernal seeks a highly motivated principal scientist for antibody development and production. The successful candidate will partner with external collaborators (e.g., CROs, CDMOs) to lead the design, development, and production of novel antibodies for targeted LNP applications. This successful candidate will also be responsible for establishing internal antibody production and analytical capabilities to support preclinical research as well as external development activities. Responsibilities: Lead antibody development, production, and scale-up for preclinical research activities as well as GMP manufacturing. Responsible for reviewing and approving critical documentation (e.g., protocols, process development batch records, analytical methods, specifications, etc) Establish internal capabilities for the development, production, and analysis of antibody supplies to accelerate and troubleshoot external development activities and provide materials for preclinical research. Review, supervise, and/or execute experiments to optimize cell culture, harvest, and downstream purification. Author tech transfer documentation (e.g., process descriptions, bill of materials, draft specifications, analytical methods) based on both external collaborator activities and internal development activities. Maintain thorough and detailed electronic laboratory notebooks Analyze, interpret, and summarize experimental data Communicate results to team and management in technical reports and oral presentations Requirements: Degree in Chemical/Biomedical Engineering, Pharmaceutical Sciences, Biochemistry, Analytical Chemistry or a similar field .
