We design novel peptide-based medicines for complex diseases where patients still have too few good options. Our team brings together people with different strengths and a shared commitment to getting meaningful work done, with each person playing a direct role in moving the company forward.

A lean team keeps us creative, collaborative, and closely connected to the work. Everyone knows what the company is working toward, everyone has a voice, and no one is limited to a narrow corner of the job description.
