Director, Immunology


Icosavax, Inc. is a publicly traded (NASDAQ: ICVX) biopharmaceutical company leveraging its innovative VLP platform technology to develop vaccines against infectious diseases, with an initial focus on life-threatening respiratory diseases. Icosavax’s VLP platform technology is designed to enable multivalent, particle-based display of complex viral antigens, which it believes will induce broad, robust, and durable protection against the specific viruses targeted. Icosavax’s pipeline includes vaccine candidates targeting respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and severe acute respiratory syndrome coronavirus 2 (SARSCoV-2). Icosavax was formed in 2017 to advance the breakthrough VLP technology from the Institute for Protein Design at the University of Washington with the goal to discover, develop, and commercialize vaccines against infectious diseases. Icosavax has an experienced management team, has raised over $350M to date, and is based in Seattle.

The Icosavax preclinical development group is seeking a Director level scientist with a strong immunology and/or virology background to help progress our preclinical pipeline and provide leadership for our vaccine efforts. The Director will help define criteria for advancing programs through preclinical development, identify potential external collaborations and define and execute internal studies. The Director will also collaborate with internal teams and external vendors on development projects and cooperate and grow with the scientific team and the broader company at large.
