Join the Spark Team

We were born of innovation, springing from the curiosity, imagination and dedication of remarkable scientists and healthcare visionaries. Our shared mission is to challenge the inevitability of genetic disease by discovering, developing, and delivering treatments in ways unimaginable - until now.

We don't follow footsteps. We create the path.


At Spark Therapeutics, a fully integrated, commercial company committed to discovering, developing and delivering gene therapies, we challenge the inevitability of genetic diseases, including blindness, hemophilia, lysosomal storage disorders and neurodegenerative diseases.

Founded in March 2013 as a result of the technology and know-how accumulated over two decades at Children’s Hospital of Philadelphia (CHOP), our investigational therapies have the potential to provide long-lasting effects, dramatically and positively changing the lives of patients with conditions where no, or only palliative, therapies exist. Greater understanding of the human genome and genetic abnormalities have allowed our scientists to tailor investigational therapies to patients suffering from very specific genetic diseases. This approach holds great promise in developing effective treatments to a host of inherited diseases. Our initial focus is on treating orphan diseases.

Headquartered in dynamic Philadelphia, we are a diverse, experienced team united in our goal to break down barriers for people and families affected by genetic diseases. As our name suggests, our investigational, one-time therapies are designed to spark healthy biology, and deliver potentially life-altering transformation for people and families affected by genetic disease. Spark is a member of the Roche Group.
