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

PhD in Immunology, Cancer Immunology, Oncology, Molecular/Cell Biology, or other Science field with 2+ years post‑PhD of hands‑on immunology/immuno‑oncology (T‑cell biology) experience in academia or industry setting.

Preferred Qualifications:

Experience with driving early drug discovery projects and leading cross-functional teams,

Expertise developing, running complex T‑cell functional assays (activation receptors, costimulatory molecules, checkpoint receptors) and interpreting mechanistic data to inform early development

Experience in designing, executing, and interpreting in vitro assays for drug discovery, including tumor models and pharmacology experiments

Clear, crisp communicator; highly organized multi-tasker who adapts quickly to deliver on‑time data packages

Confident influencer who engages senior leadership and thrives in a matrixed organization

Proven scientific impact, publications and contributions advancing new therapeutic concepts

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
