Lexington, MA, US
Our Boston Research & Development hub, anchored in the greater Boston area, brings together the best minds in life science innovation. The teams located in facilities in Lexington, Watertown and Cambridge reflect the full R&D continuum, from early research through late‑stage clinical development. Here, we are building for the future, creating a distinct R&D community based on collaboration, partnerships, and cutting‑edge research across multiple modalities and therapeutic areas.
We recognize that improving human health starts here and that patients rely on us. Our greater Boston R&D hub merges biotech speed and agility with large pharmaceutical company quality, resources, and stability, uniting the best of both worlds to develop new medicines for patients.
The team is composed of collaborative, diverse and passionate people who have a true sense of pride in their work and are committed to helping others grow and develop their careers. You’ll also have a platform to engage with key stakeholders on a global scale throughout the entire pipeline process. While changing the future of diabetes, obesity and MASH treatment is no easy task, we also recognize the importance of an enjoyable workplace, which is why we’ve cultivated a culture of fun, ingenuity and innovation.
And our competitive compensation package and support of a healthy work‑life balance all add to a best‑in‑class employee experience. Are you ready to make a difference?
The Principal Scientist in Medicinal Chemistry will be responsible for leading drug discovery projects within Small Molecule Research (SMR) from target evaluation, selection, hit validation to development candidate nomination. Additionally, the Principal Scientist will contribute to external diligence and support external project collaborations.
Responsibilities include:
Setting the chemistry strategy for projects and advancing drug discovery programs by collaboratively interacting cross‑functionally within NN; being the co‑project lead on the overall program strategy to meet product target profiles (PTPs) and deliver low dose oral drugs; leading and managing a number of contract research organizations (CRO) and external chemistry partners across the globe; leading the preparation of patents, reports, and scientific publication;
and serving as functional expert in due diligences for assets in‑licensing and discovery partnerships. Evaluation of in‑licensing and collaboration opportunities and working closely with external partners to drive small molecule collaboration project deliverables and milestones.
Reports to Sr Director, Small Molecules (NN) Small Molecule Research (SMR) in Therapeutic Discovery (TD). Will interact and closely collaborate with other Small Molecule Research Scientists (chemists, biochemists, Biophysicists, structural biologists), the broader Small Molecule & Cross Modality Research (in‑vitro pharmacology, formulation) (SMCMR), Data Science & Innovation and computational chemists (ADI), the Therapeutic Areas (TA), Drug Metabolism and Pharmacokinetics (DMPK), toxicology, pharmacology and translational medicine teams globally.
Will interact daily with Chemistry CROs and Comp Chemistry CROs globally.
