Chemical Engineer/Materials Scientist I

Arsenal Medical Inc. is a Boston metro based, privately held, clinical stage, medical device start-up company committed to transforming medicine through the novel application of in situ forming materials to meet today's challenging unmet clinical needs. Our in situ forming biomaterials platform creates customized mechanical implants in the body to control the flow of bodily fluids, fill complex anatomical spaces, and/or apply physical pressure. These implants are formed by delivering liquids with tunable chemistries to specific locations in the body using minimally invasive delivery systems. Once at the target anatomy, the liquids react to form solid implants that take the shape of complex cavities in the body. We create solutions that address some of today’s most challenging and critical unmet medical needs.

We have an opening for a recent graduate with experience in chemical engineering or polymer and material science to join our team. This position will be hands-on, laboratory based, and will support projects developing novel in-situ forming medical devices.
