Job description

What's happening at Entrada Therapeutics? Entrada is a clinical-stage biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines that engage intracellular targets that have long been considered inaccessible. Through proprietary and versatile approaches, Entrada is advancing a robust development portfolio of genetic medicines for the potential treatment of neuromuscular and inherited retinal diseases, among others. Our lead oligonucleotide programs are in development for the potential treatment of people living with Duchenne muscular dystrophy (DMD) who are exon 44, 45, 50 and 51 skipping amenable. Entrada has partnered with Vertex Pharmaceuticals to develop a clinical-stage program, VX-670, for myotonic dystrophy type 1 (DM1).

2026 represents a catalyst-rich period for Entrada. We expect multiple clinical data readouts as we advance several DMD programs across the U.K., EU, and U.S. By year-end 2026, we anticipate four clinical-stage programs in our DMD franchise (ENTR-601-44, ENTR-601-45, ENTR-601-50, and ENTR-601-51). These programs are complemented by the ongoing clinical progress of our DM1 collaboration with Vertex (VX-670).

We are a tight-knit team of experts and leaders in both therapeutic development and rare diseases and are excited to grow and attract colleagues who are ready to join a high-energy, dedicated team that likes to get things done and dramatically improve the lives of patients and their families.

The Perfect Addition to Our Team

You are passionate and dedicated to your work, with a commitment to overcome challenges and deliver on our potential to develop transformative therapies for patients and their caregivers. You bring energy and enthusiasm to your role, while recognizing that a steady and consistent effort is required to successfully develop novel medicines.
