About our R&D Institute in Paris Saclay

At the heart of one of the world's top eight innovation clusters, the Servier R&D Institute at Paris-Saclay is where visionary science meets a powerful global ecosystem. By uniting our Group's innovation potential with this prestigious center of excellence, we are not only accelerating the future of therapeutic discovery but also championing the global influence of French research.

Are you a fast-learning scientist passionate about optimizing clinical drug trials through the investigation of endogenous biomarkers ? We are seeking a Scientist to join our R&D organization. In this role, you will develop robust protocols to extract liver-derived extracellular vesicles (EVs) from culture media and human plasma and apply MultiOMICS (Proteomics and Transcriptomics) to monitor CYP450 and drug transporter induction/inhibition. Your work will reduce reliance on dedicated clinical DDI studies and feed into our global DDI monitoring strategy throughout clinical development.

Responsibilities

Design and conduct experiments with primary human hepatocytes, relevant cell lines, and human samples to set up, test, and optimize liver-derived EV isolation/enrichment protocols

Evaluate the reliability of EV-based readouts to assess xenobiotic impacts on ADME protein expression (CYP450 and drug transporters induction/inhibition)

Optimize sample preparation to maximize data yield from minimal plasma volumes

Perform quantitative studies of global protein and gene expression in extracted EVs and monitor induction effects

Work transversally with scientists across R&D to execute experiments and generate/analyze proteomics and transcriptomics datasets

Communicate results internally (presentations/posters) and externally (peer-reviewed journals, posters, conferences), where applicable

Contribute to general lab activities, including mentoring undergraduate/graduate students and participating in science outreach, where applicable

Profile

PhD in biochemistry, molecular biology, cell biology, or equivalent

Proven experience with extracellular vesicle extraction and analysis

Expertise in sample preparation and core biochemical methods (WB, ELISA, qPCR)

Proficiency in proteomics, genomics, and transcriptomics is valued

Some bioinformatics experience for protein identification and gene expression analysis

Knowledge of pharmacokinetics and cell culture is a plus (not required)

Ability to mentor internship- or technician-level collaborators

Team-oriented, results-driven, curious, and autonomous

Strong communication skills with demonstrated experience writing and publishing in international peer-reviewed journals

Our standard recruitment journey includes the following steps:

Prequalification Interview

Interview with the Manager

Interview with Talent Acquisition Team / Human Resources

Reference Check Process

At one stage of the process, we would be delighted to welcome you to our site to meet in person and share the environment where we work every day to transform patients' lives!

Please note that this recruitment process may be adapted based on the specific requirements of the position.
