Director, Program Management

Location: Watertown, MA (On-site)

Reports to: SVP, Finance & Corporate Development

About the Company:

Diagonal Therapeutics is a clinical-stage biotechnology company pioneering a new class of medicines. While nearly every antibody drug works by blocking an overactive signal, Diagonal does the opposite — our clustering antibodies bridge two receptors at the cell surface to turn normal signaling back on, reaching diseases the blocking model cannot. Our lead program, DIAG723, is the first clustering antibody in the clinic, designed to address the root cause of both hereditary hemorrhagic telangiectasia (HHT) and pulmonary arterial hypertension (PAH). Behind it, our platform pairs computational and experimental discovery to build a pipeline across cardiovascular, renal, and other diseases.
