Scientist Bioscience in vivo, Respiratory and Immunology

AstraZeneca is a global, science-driven biopharmaceutical company. We are dedicated to discovering, developing, and delivering innovative, meaningful medicines and healthcare solutions that enrich the lives of patients. The vision of AstraZeneca Respiratory & Immunology (R&I)iscenteredon delivering life-changing products that advance world health and help fight and cure disease. R&I is one of three main therapeutic research areas within AstraZeneca that deliver candidate drugs into late-stage clinical development. We are building new capabilities to support our growth in immunology and autoimmune diseases, and we have an exciting opportunity for an in vivo scientist looking to help bring new medicines to patients.

As a part of a growing in vivo Bioscience team within the R&I department, we areseekinga highly motivatedscientistwithhands-on in vivo skillsto join our collaborative team. This candidate would have experience in immunology or related discipline. This is a lab-based position. The role will initially be based in Waltham, MA within AstraZeneca’sstate-of-the-artlaboratories where you will follow the science to help drive innovation and advance medicine to help improve patient lives. InOctober2026 we will belocatedat the newstate of the artfacilities in Kendall Square Cambridge.

Main Duties and Responsibilities

In this role, you will be anin vivoexperimental scientist within Respiratory and Immunology Department focusing on developing therapeutics for the treatment of immune and autoimmune diseases such as SLE,fibrosisand arthritis using mouse models. You will generate preclinical and translational data in support of key portfolio programs and drive technical excellence in bioscience research.Strongexpertisein in vivo mouse modelsandhands-on in vivo skillsisrequiredand multiparameter flow cytometry, multiplex cytokine read-outs, qPCR is essential. The role will sometimes involve implementing protocols over timelines that extend outside of normal working patterns.
