AI Summary

Develops physics-based and data-driven models for Li-ion battery cell degradation, implements simulations in tools such as COMSOL and PyBaMM, performs life estimation studies, and collaborates with battery scientists to support product development from early design through production.

About this role

Verkor is a French industrial company aiming to pioneer low-carbon battery manufacturing in France. With the backing of prominent industrial companies such as Renault Group, Plastic Omnium and Schneider Electric, Verkor intends to electrify the future of European mobility.

With over 750 experts from 48 different countries, our endeavor is to unite exceptional global talent to bring this ambitious and innovative project to life. Our strong and agile international team continues to grow and adapt to new challenges. Based in Grenoble and Dunkirk (France), we have recently started operations our Verkor Innovation Centre (R&D centre and 4.0 pilot line).

We now focus on building the world’s most modern and efficient Gigafactory in Dunkirk (France). With this facility, our ambition is an initial annual production of 16 Gwh of lithium-ion batteries by 2025, thus powering 300,000 electric vehicles annually.

In joining us you will actively participate in this breathtaking industrial adventure to shape the future of European mobility.
