Circle Pharma is an emerging biotech company discovering and developing macrocycle therapeutics targeting important intracellular protein-protein interactions. Our novel, intrinsically cell-permeable macrocycles provide a unique opportunity to address these “undruggable” targets.  Our first targets are in molecularly defined cancers, with future expansion to other therapeutic areas. 

We are a tightly integrated team of synthetic and computational medicinal chemists and pre-clinical biologists. Our discovery platform includes structure based design, integrating target affinity, cell permeability and medicinal chemistry, and automated macrocycle synthesis. We have open positions for candidates who want to make key contributions to a small, exciting startup company and help drive its growth.  For more information about Circle Pharma, see our website at www.circlepharma.com.

Job Description

We are seeking a highly skilled and motivated Research Associate, Senior Research Associate or Scientist with a strong background in synthetic organic chemistry to join our expanding medicinal chemistry department.
