Company Overview 

At Avidity Biosciences, we are passionate about the impact of every employee in bringing potentially life-changing therapeutics to patients in need. Avidity is pioneering a new class of oligonucleotide-based therapies called AOCs, designed to overcome the current limitations of oligonucleotide therapies to treat a wide range of serious diseases. We utilize our proprietary AOC platform to design, engineer and develop transformative therapeutics that combine the tissue selectivity of monoclonal antibodies (mAbs) and the precision of oligonucleotide-based therapies to access previously undruggable tissue and cell types and more effectively target underlying genetic drivers of diseases. If you are a committed, solution-oriented thinker, come make a difference with us.
