About Sanofi:

We’re an R&D-driven, AI-powered biopharma company committed to improving people’s lives and delivering compelling growth. Our deep understanding of the immune system – and innovative pipeline – enables us to invent medicines and vaccines that treat and protect millions of people around the world. Together, we chase the miracles of science to improve people’s lives.

Your responsibilities:

• As part of matrix project teams, develop and deploy mechanistic, hybrid and data-driven modelling solutions to support downstream process development activities for a broad range of biopharmaceuticals.

• Use programming languages such as Python, MATLAB, R to translate complex mathematical models into clean and reusable codes for model use and implementation.

• In coordination with the process development group and working closely with the Data Science team, design and analyze targeted experiments required to calibrate and verify model performance.

• Act as a change agent to support the implementation of process modelling in established process development workflows for targeted downstream unit operations.

• Document Progress against deliverables with rigorous scientific communication via technical presentations, reports and, when appropriate, scientific publications.

• Track progress against deliverables and maintain a communication plan with key stakeholders and partners across departments.

For this position, knowledge in biologics downstream unit operations (chromatography, viral inactivation, ultrafiltration/diafiltration) is required. This is an exciting opportunity to demonstrate the benefits of process modelling and data science in a cutting-edge scientific department developing the next generation of Sanofi medicines that will improve the quality of life for patients across the world.

Basic Qualifications:

• PhD in Chemical, Biochemical Engineering or Bioengineering or MSc with 4 years of industrial experience.

• Research or industrial track record of developing process models for downstream unit operations for biologics such as affinity/ion exchange chromatography, ultra/ nano / tangential flow filtration for process design, scale-up, scale-down and/or process control purposes.

• Demonstrated ability to translate mathematical models into computer programs using programming languages such as MATLAB, R, Python or similar.

• Domain knowledge in Biology with industrial or academic experience in downstream process development and/or manufacturing.

Preferred Qualifications:

• Demonstrated knowledge and application of Machine Learning / Multivariate analysis methodologies to biological processes.

• Experience with downstream process simulation software such as CADET, gPROMS or goSilico

• Experience in continuous bioprocess manufacture with associated Model Predictive Control (MPC).

• Solid track record of publications in the field of process modelling/process simulation in peer reviewed journals.

Beyond technical skills you will also have a solid track record in project management with an ability to communicate with transparency with your peers and with senior stakeholders.

This cross functional role will require intellectual agility to work across site/function boundaries in Sanofi’s global CMC organization.
