Biotech Research Scientist for DNA Synthesis Platform – DNA Script, Paris, France

DNA Script

DNA Script is a leading company in manufacturing de novo synthetic nucleic acids using an enzymatic technology. The company aims at accelerating innovation in life science and technology through quick, decentralized solutions for laboratory work in life science and genomics. DNA Script’s approach leverages nature’s billions of years of evolution in synthesizing DNA to set a new standard for how nucleic acids are made and accelerate the adoption of synthetic biology across diverse disciplines such as biopharma, sustainable chemistry and data storage.

To date, DNA Script has raised over 58 M€ of financing, mostly through equity funding brought by prestigious players such as Illumina Ventures, LSP, Merck Ventures, Sofinnova Partners, BPIFrance, Kurma Partners and Idinvest. The company partners with leading institutions, in particular Institut Pasteur.

We are looking to assemble a team of world class, innovative and passionate people gathering their talents and skills to achieve one goal: unlock the power of DNA to write the future of life sciences. We offer the opportunity to join a dynamic, international and highly skilled team in a high-performance biotech startup. We offer a competitive benefits package (salary, equity, healthcare, meal vouchers and public transportation) along with a unique opportunity to work in the heart of Paris.

The role

DNA Script’s technology performs synthesis by adding one nucleotide at a time. This iterative process requires to cycle the same steps, such as dispensing, shaking and heating, over and over in order to synthesize DNA fragments of several hundred nucleotides. The process needs to be automated in a robust, reliable, and precise way to achieve high quality synthesis. DNA Script is looking for a talented individual to join the Synthesis platform team, in charge of providing to the rest of DNA Script oligos for application development as well as quality data for the R&D team.

This platform plays a centre role for DNA Script by evaluating new reagents and their stability, performing synthesis for enzyme screening and qualification and by providing DNA to the application development team. To do so, the candidate will need to interact with many different teams, understanding their needs and optimizing synthesis runs. He or she will be in charge of the day to day operations in particular in setting -up the DNA synthesis runs on the DNA synthesis platform in order to provide essential data and oligos to the rest of the company.

The candidate will be running and tracking the necessary tests and processes to ensure day to day reproducibility, excellent synthesis and data quality. This work will be performed on standard liquid handling systems. We are seeking an individual who is well organized, detail-orientated, enjoys problem-solving, and is able to work in a multi-disciplinary role. The candidate will have to be handy and a quick learner to accurately grasp the subtilities of the liquid handlers.
