Clinical-stage RNAi biotech advancing siRNA therapeutics from discovery to regulatory approval
Arrowhead Pharmaceuticals is a public biotech firm developing RNA interference (RNAi) therapeutics, with 501–1,000 employees split between discovery, manufacturing, and clinical operations. The hiring footprint reveals a manufacturing-heavy operation: 31 of 154 active roles target manufacturing roles, with significant concurrent staffing in research and quality—a profile consistent with ramping GMP production and regulatory submissions for clinical candidates. Pain-point concentration on compliance, inspection readiness, and vendor management signals active engagement with FDA oversight and supply-chain hardening ahead of or during regulatory reviews.

Arrowhead Pharmaceuticals develops RNA-targeting therapeutics, primarily using RNAi to address difficult-to-treat diseases. The company operates across three interconnected domains: early-stage antibody and peptide ligand optimization (active projects in siRNA delivery and antibody screening), manufacturing and supply-chain scaling (raw materials qualification, SOP lifecycle management), and regulatory pathway advancement (clinical integration, submissions, inspection coordination). Current hiring velocity is accelerating, with particular depth in manufacturing, research, and quality functions. The organization maintains operations in the United States and Peru, and employs Veeva (clinical data and regulatory submissions), Benchling (lab informatics), and analytical instrumentation (LC-MS, HPLC, qPCR) as core technical infrastructure.
Active projects span antibody and peptide ligand development for siRNA delivery, raw materials supplier qualification, plozasiran evidence generation, regulatory submissions and clinical pathway integration, and quality/compliance systems (SOP management, risk/control plan development, digital workflows).
Arrowhead has 10 active engineering roles open and is accelerating hiring. The company also has 31 manufacturing roles, 30 research roles, 20 ops roles, and 14 healthcare roles currently posted.
Core tools include Veeva (clinical data, regulatory submissions, vault management), Benchling (lab informatics), analytical instrumentation (LC-MS, HPLC, qPCR), SAS, Dynamics 365, Power BI, and Microsoft 365 suite (Windows 11, Azure AD, Intune).
