The Role

Arrowhead Pharmaceuticals, Inc. (Nasdaq:  ARWR) is a clinical stage biopharmaceutical company that develops medicines that treat intractable diseases by silencing the genes that cause them. Using a broad portfolio of RNA chemistries and efficient modes of delivery, Arrowhead therapies trigger the RNA interference mechanism to induce rapid, deep, and durable knockdown of target genes. RNA interference, or RNAi, is a mechanism present in living cells that inhibits the expression of a specific gene, thereby affecting the production of a specific protein. Arrowhead’s RNAi-based therapeutics leverage this natural pathway of gene silencing.

Arrowhead is focused on developing innovative drugs for diseases with a genetic basis, typically characterized by the overproduction of one or more proteins that are involved with disease. The depth and versatility of our RNAi technologies enables us to potentially address conditions in virtually any therapeutic area and pursue disease targets that are not otherwise addressable by small molecules and biologics. Arrowhead is leading the field in bringing the promise of RNAi to address diseases outside of the liver, and our clinical pipeline includes disease targets in the liver and lung with a promising pipeline of preclinical candidates.

Arrowhead’s corporate headquarters is in Pasadena, CA with research and development teams in Madison, WI & San Diego, CA, and a state of the art manufacturing facility in Verona, WI.  Our employees are nimble, science-driven innovators who are collaborating to bring new therapies to patients in need. 

The Position

The Corporate Communications Intern will join Arrowhead Pharmaceuticals’ Corporate Communications team and play a hands-on role in telling the story of our science, our people, and our impact. This internship offers a unique opportunity to act as an internal journalist—interviewing subject-matter experts, developing compelling content, and helping shape how Arrowhead communicates with employees and external audiences. The intern will contribute to high-visibility projects that strengthen brand storytelling, enhance internal communications, and elevate Arrowhead’s digital presence across platforms.

This is an 11-week Summer Internship Program paying $24.00 per hour and requires full-time, onsite work five days per week at the designated location.

Responsibilities

  • Support brand storytelling and content development by interviewing experts across the organization and writing engaging articles for internal and external use.
  • Develop written content that may be published throughout the year across owned channels and social media platforms.
  • Contribute to the development of an owned media strategy outlining how content is created, distributed, and amplified.
  • Support internal communications program development, including needs assessments, research into best practices, and collaboration with People & Culture teams.
  • Assist with establishing and executing internal communication channels such as employee newsletters, surveys, and all-company meeting enhancements.
  • Support digital asset creation and management, including helping to establish a digital asset management (DAM) system.
  • Populate and organize digital assets such as photography, videography, and design files.
  • Coordinate and, where applicable, directly support photography, videography, audio, or podcasting projects.
  • Collaborate with leaders and teams across multiple functions and sites to gather insights and content.

Requirements

  • Currently enrolled student at an accredited university or college, with at least one year completed toward a degree in Journalism, Communications, Digital Media, or a related discipline.
  • Strong interest in journalism, communications, digital media, social media, or a related field.
  • Excellent written and verbal communication skills at the university level.
  • Strong problem-solving and organizational skills.
  • Ability to collaborate effectively with stakeholders across functions in a fast-paced environment.
  • Proficiency in Microsoft Office applications.

Preferred

  • Experience developing articles or written content through interviews with subject-matter experts.
  • Experience translating scientific or technical topics for diverse audiences.
  • Interest in or experience with photography, videography, graphic design, audio, or podcasting.
  • Strong curiosity, creativity, and passion for brand storytelling and thought leadership.
