In the race for the future of health – The Sanofi mRNA Center of Excellence

At Sanofi, we believe in a world in which no one suffers or dies from vaccine-preventable diseases. And while the pandemic has shaken up our industry, creating new opportunities and risks, we believe the acceleration of innovation with mRNA technology means vaccines for more people faster than before.

That’s why we’re looking for bold, optimistic world-changers to join the team at our mRNA Center of Excellence. We’re investing €400m a year into the new Center, hiring a team of 400 dedicated employees for it and using it as the foundation to implement integrated end-to-end mRNA vaccine capabilities and research with R&D, digital and CMC teams.

Bring your ambition and optimism for the future to Sanofi. Join us.

About the Opportunity

As an experienced mRNA ML Data Scientist, you will lead data analysis, ML and modelling efforts for design and optimization of best-in-class mRNA vaccines and therapeutics as part of the Data and Computational Science team in the mRNA CoE. This team brings end to end data integration and advanced analytics (pre-clinical, biomarkers, process development, CMC, clinical) in the mRNA CoE. Deploying and exploiting digital solutions (AI/machine learning, data, analytics) to integrate the full data value chain, extracting actionable information for a move to a full data driven strategy, and decision-making process, to increase probability of success and to accelerate mRNA vaccines and therapeutics development and launch. In this position, you will work in collaboration with other mRNA CoE platforms scientific and technical experts located in the US and in France, bringing practical knowledge and experience in applying Machine Learning (ML) for design and optimization of mRNA vaccines and therapeutics. We look for scientists with deep expertise in the mathematics and theoretical underpinnings of machine learning and deep knowledge and experience in RNA biology/biophysics/biochemistry.


In this role you will

  • Collaborate with stakeholders and other group experts in the development and execution of the scientific strategy and technical solutions to develop best-in-class mRNA vaccines and therapeutics
  • Be responsible for identifying, setting strategy and delivering 1 to 2 end to end ML data science projects for design and optimization of mRNA sequences and formulations and predict performance for vaccines and therapeutic applications
  • Act as a scientific expert and partner in the fields of RNA biology/biochemistry/biophysics and AI/ML
  • Design and assess studies to evaluate the performance of mRNA vaccines and therapeutics. Translate experimental learnings into the development and refinement of computational models for design, optimization, selection and formulation of mRNA vaccines
  • Develop and evaluate computational and statistical methods for data analysis
  • Responsible for designing, prototyping, and validating computational solutions to diverse scientific challenges in the fields of mRNA vaccines and therapeutics
  • Develop, deploy, and assess the results of at-scale models at varying levels of model granularity encompassing heterogeneous preclinical and clinical data
  • Employ machine learning methods such as deep learning, neural networks, reinforcement learning, graphical and generative models to deconvolve high dimensional experimental and in silico modelling results
