At Eisai, satisfying unmet medical needs and increasing the benefits healthcare provides to patients, their families, and caregivers is Eisai's human health care (hhc) mission. We're a growing pharmaceutical company that is breaking through in neurology and oncology, with a strong emphasis on research and development. Our history includes the development of many innovative medicines, notably the discovery of the world's most widely-used treatment for Alzheimer's disease. As we continue to expand, we are seeking highly-motivated individuals who want to work in a fast-paced environment and make a difference. If this is your profile, we want to hear from you.

General Summary:

The Eisai Center for Genetics Guided Dementia Discovery (G2D2) is an industry-unique drug discovery biotech with a diverse group of passionate, dedicated and collaborative scientists committed to helping eradicate Alzheimer's disease and other dementias. Recognizing the potential for human genetics, data sciences and precision chemistry to disrupt the drug discovery paradigm, Eisai established G2D2 to accelerate the discovery of innovative therapeutics. G2D2 is committed to accelerating drug discovery premised upon robust insights from human biology, and driving multi-disciplinary team-based progress towards addressing real unmet patient needs.

At G2D2, we focus not only on how such data help identify and validate therapeutic targets, but also to guide novel approaches to drug such targets and match them to the right patient at the right time. Our precision chemistry strategy - in the context of insights from human genetics - is uniquely positioned to deliver tailor-designed small molecule, anti-sense oligo-nucleotide, and other solutions for targeted therapeutics.

Our new cutting-edge 50,000-square-foot facility is strategically locatedin Cambridge, MA,to accelerate collaborations with leading research institutesin thisworld-class biotech hub. Our facility has been designed around a novel open-lab concept, enabling chemists, biologists, automation and other scientists to work together in a single common and integrated lab space. Our labs include state-of-the-art capabilities in medicinal and process chemistry, in-vitro and in-vivo biology, microscopy, chemical and structural biology, automation and screening, and several other discovery technologies and platforms.

You will join a highly interactive and collaborative team spanning a broad range of drug discovery capabilities. We highly value both internal and external collaborations, and you will become involved in flexible research models with a range of external scientific partners to accelerate delivery of innovative medicines. As an Eisai employee you will spend at least 1% of your working time with patients and families to ensure that the innovation you drive is based on an understanding of their real needs.
