DNA Synthesis Engineer

Scipio Bioscience is a start-up company developing an innovative solution for sample preparation in single-cell RNA sequencing (scRNA-seq). This solution, based on a kit format and complemented by a SaaS product for the analysis of the data from this kit, will allow decentralized and flexible sample preparation in all laboratories and will provide the means for new advances first in transcriptomics but also in all fields of clinical and fundamental research. Hosted in the heart of Paris (Institut du Cerveau, Pitié Salpêtrière), it has a multidisciplinary team of about twenty people and is supported by a recent €6 million fundraising campaign.
