Job Description

Our Company's Device Product and Process Development (DPPD) Team is seeking a hands‑on device characterization and design focused scientist. This position will be responsible for technical interrogation of the various drug delivery device technology platforms supporting our Company's pipeline to identify risks (i.e. when/how will the device fail?) and opportunities for improvement.

They will utilize a wide variety of cutting‑edge analytical instruments and methods, including in silico modeling, to build fundamental understanding of the devices’ material and functional properties and attributes. This understanding, combined with extensive data analysis/interpretation, will allow the role to design and develop functional improvements for these platforms and, as the opportunities arise, develop new and novel delivery technologies.

These drug delivery device technology platforms are often assemblages of glass pre‑filled syringes, injection moulded plastic components driving delivery of a drug, typically though mechanical or electro‑mechanical means. Examples include, but not limited to, autoinjectors and inhalers.

Our Company is on a quest for cures and is committed to being the world’s premier, most research‑intensive biopharmaceutical company. Today, we’re doubling down on this goal. Our Company's Research Laboratories is a true scientific research facility of tomorrow and will take Our Company's leading discovery capabilities and world‑class small molecule and biologics R&D expertise to create breakthrough science that radically changes the way we approach serious diseases.

Join us and experience our culture first‑hand — one of strong ethics & integrity, diversified experiences, exceptional science, and a resounding passion for improving human health. As part of our global team, you’ll have the opportunity to collaborate with talented and dedicated colleagues while developing and expanding your career.
