Job Title: Senior Scientist (CLD) – Cell Therapy Safety
Location: Cambridge, UK
Do you have a background in cell therapy safety assessment and want to shape the safety strategy for innovative cellular therapeutics? Are you excited to expand your expertise in the non-clinical safety assessment of next-generation cellular modalities? If yes, AstraZeneca could have the role for you.
About the role
We are seeking a highly motivated Senior Scientist to join our laboratory-based Cell Therapy Safety Team within Cell Therapy Translational and Safety Sciences. This role is based at our state-of-the-art Discovery Centre in Cambridge, UK, offering a collaborative environment across disciplines to drive innovation in 21st-century pharmaceutical research.
At AstraZeneca, we value diverse perspectives and inclusive collaboration. We believe teams are most creative when individuals contribute different ideas and experiences in an environment where those differences are welcomed and respected. This is how we foster continuous innovation, learning, and growth—for our people and for patients.
What you’ll do
You will primarily support our growing cellular medicine portfolio; including autologous, allogeneic and in vivo CAR-T. You will design and execute assays and apply molecular biology and immunology/cell biology approaches to develop methods for assessing pre-clinical safety.
Key responsibilities include:
- Model development: Develop and validate new in vitro models to predict and assess toxicity, immunogenicity, and tumorigenicity for cellular therapeutics; contribute to broader non-clinical toxicology packages for novel modalities.
- Scientific problem-solving: Identify and solve complex scientific problems; champion scientific and technological innovations that advance strategic capabilities.
- External engagement: Collaborate with leading academics; publish in high-quality journals; actively contribute to scientific networks and communities.
- Innovation: Drive innovation to support internal and external presentations and publications to strengthen AstraZeneca’s scientific leadership.
- Cross-functional collaboration: Work closely with scientists across CPSS and partnered functions to translate biological insights into safety strategies for pioneering therapeutics.
