Pionyr Immunotherapeutics is a clinical stage company developing cancer immunotherapies that target the tumor microenvironment to enhance the body’s antitumor immunity. The company’s approach, Myeloid Tuning™, is designed to enhance the immune system’s anti-tumor response by altering, or “tuning”, the myeloid infiltrate of the tumor microenvironment with high specificity and for very specific purposes.

The company was founded in 2015 by Max Krummel, Ph.D., a professor at University of California, San Francisco School of Medicine (UCSF), who has been making significant strides in immuno-oncology since the mid-1990s. Dr. Krummel is the co-inventor of YERVOY® (ipilimumab), the first checkpoint inhibitor, which was approved in 2011 to treat melanoma. Pionyr has exclusively licensed technology from UCSF based on Dr. Krummel’s work.

Our employees are passionate about Pionyr’s mission: To develop innovative therapeutics that dramatically alter the tumor microenvironment thereby enabling the human immune system to successfully fight and, potentially, eliminate cancer. We offer an environment where individuals make a difference and have a voice. At Pionyr, communication is open and transparent, teams are empowered, and quality and integrity are paramount.

We greatly value our employees, and this is reflected in the comprehensive and above market compensation and benefits packages we provide to support the health and well-being of our “Pionyrs” and their families.

Join us and become an integral part of a leading immune-oncology company where you will have a direct impact on our research and clinical programs and have an opportunity to learn from proven, experienced scientific and business leaders. We look forward to hearing from you.
