Manufacturing Engineer

Prellis Biologics employs 2-photon holography to print human tissues and organs in real time. Current applications of our platform include printing of lymph node organoids, which we are using to generate in vitro human antibody libraries, camelid antibody libraries, in vitro human immunogenicity screening, human primary tumor/lymph node co-cultures for therapeutic screening, and vaccine R&D. Prellis’ ability to print and culture healthy human tissue provides it with unique opportunities for generating and screening next generation human therapeutics.

Prellis Biologics is seeking a Manufacturing Engineer to drive the research and development of proprietary next generation bioprinting technology and associated production infrastructure.
