Job Description

About Arrowhead Pharmaceuticals, Inc.

Arrowhead Pharmaceuticals, Inc. (Nasdaq: ARWR) is a pioneering clinical stage biopharmaceutical company dedicated to developing medicines that treat intractable diseases. Our core mission is achieved by silencing the genes that cause illness, leveraging a broad portfolio of RNA chemistries and efficient delivery methods. Our therapies trigger the natural RNA interference (RNAi) mechanism to induce rapid, deep, and durable knockdown of target genes, effectively inhibiting the expression of specific genes and the production of disease-causing proteins.

Arrowhead focuses on developing innovative drugs for diseases with a genetic basis, particularly those characterized by the overproduction of problematic proteins. The versatility of our RNAi technologies allows us to address conditions in virtually any therapeutic area and target diseases not treatable by small molecules or biologics. We are at the forefront of extending the promise of RNAi beyond liver-based diseases, with a robust clinical pipeline targeting diseases in the liver and lung, complemented by a promising array of preclinical candidates.

Our corporate headquarters are located in Pasadena, CA, with cutting-edge research and development teams in Madison, WI & San Diego, CA, and a state-of-the-art manufacturing facility in Verona, WI. Our team comprises nimble, science-driven innovators who are collaboratively working to bring new therapies to patients in need.
