This role does not offer sponsorship for work authorization. External applicants must be eligible to work in the US. Your Role:

Help to shape next generation cancer immunotherapies at EMD Serono. As an In Vitro Principal Scientist, you will not only execute experiments but also lead and represent the in vitro strategy on discovery teams supporting Tumor Immunology projects. Our goal is to mobilize adaptive and innate immunity—spanning antibody therapeutics, T‑cell engagers, checkpoint modulators, and myeloid/NK activators—turning bold ideas into high‑quality clinical candidates in a fast‑paced, highly collaborative environment.

Key Responsibilities:

Provide creative, strategic input—conceive new project ideas and help design execution‑ready workplans

Drive early drug discovery projects in immuno-oncology by designing, conducting and overseeing in vitro/ex vivo pharmacology studies (human immune cell / tumor cell co‑culture assays; profile function via flow cytometry, cytokine/biomarker readouts, and high‑content imaging) to support development of novel biological and small molecule agents

Build and validate human immunology models that complement animal studies to improve translational predictivity and de‑risk candidates

Scout, implement, and champion new assay platforms to investigate novel MOAs, boost data quality, throughput, and decision‑making speed

Independently generate in vitro data for target selection, lead optimization, candidate nomination; and enable program decisions toward IND‑enabling studies

Analyze, document, and present results to multidisciplinary teams and senior leadership; manage studies at CROs and academic collaborations where needed
