Avidity Biosciences is a clinical-stage biopharmaceutical company developing antibody oligonucleotide conjugates (AOCs) for rare muscle disorders and other serious diseases. The organization employs roughly 350 people and expanded its workforce by more than one-third through 125 new hires while keeping attrition in the low double digits. This balanced growth highlights the company’s continued investment in research, development, and supporting functions as it advances multiple programs through the clinic.
Engineering—which includes research, process development, and technical operations—accounts for about 29 % of all employees and remains the largest talent group at Avidity Biosciences. Business-oriented teams such as Healthcare and Business Management each represent close to 14 % of total headcount, while Operations and Finance & Administration contribute another 20 % combined. Smaller yet essential groups span Marketing & Product, Sales & Support, Human Resources, and Risk/Safety/Compliance, illustrating a broad functional base that supports the company’s scientific work and corporate infrastructure.
More than half of the workforce is based at the company’s headquarters in the San Diego area, underscoring the region’s prominence as a life-science hub. Additional concentrations of staff are located in Boston, San Francisco, and other biotech clusters including Seattle and the Raleigh-Durham corridor. Approximately 30 % of employees work in fully remote or distributed settings, giving Avidity Biosciences flexibility to tap into talent beyond its core offices.
