Research Engineer Position in Sanofi / WIDGET consortium
Expert in Biology, Molecular Biology, Sequencing
Abstract:
As part of the WIDGeT consortium1 (23M€, 5 years), we are currently researching a Research Engineer candidate with a strong background in molecular biology.
Overview of the research project:
The WIDGeT consortium (Viral Vector Intelligent Design for Gene Therapy) aims to accelerate the development of gene therapies using viral vectors derived from adeno-associated viruses (AAV) for the treatment of age-related macular degeneration and hereditary podocytopathies (kidney diseases), leveraging the potential of artificial intelligence (AI). As part of this challenging consortium, our team proposed to develop a new technology to provide very sensitive information of AAV’s transgene expression at the single cell level. This technology is based on droplet microfluidic, DNA barcoded, scRT-PCR and NGS.
Responsibilities:
- Develop and optimize molecular biology protocols
- Design tools (Probes, PCR primers, NGS primers, …) needed for the project
- Execute complex experiments
- Analyze data (Sanger)
- Write (Lab Book) and Present (PowerPoint) research findings.
- Report and collaborate with the other members of the team.
Qualifications :
- MS in biology/molecular biology
- Strong background in molecular biology
- Appetite for bench work & wet lab
- Appetite for challenging project
- Good written and verbal communication skills.
- Experience in NGS is a plus
- Experience in Single-cell RNA sequencing is a plus.
- Experience in screening is a plus.
- Knowledge in organoids/tissues preparation is optional.
- Background in Droplet microfluidic is optional.
- Experience with Recombinant AAV is optional.
The Project Team:
A dedicated team was created in 2024 to tackle this challenging project. The team is composed of one researcher, one engineer and one technician.
The Lab:
Our innovative Team (~8 people) is based in Vitry-Sur-Seine (Suburbs of Paris) at Sanofi R&D site. We have two laboratories (L1 & L2) dedicated to droplet microfluidic technology, with access to diverse technologies (ARIA Fusion (FACS), PCR, qPCR and NextSeq Illumina).
Duration & Salary:
2-3 years
Language:
English / French (optional)
