Chemistry Product Engineer / Ingénieur Produits Chimie (H/F)

Automotive Cells Company (ACC) is a joint venture created in the summer of 2020, supported by Stellantis, Mercedes-Benz, and Saft (a subsidiary of TotalEnergies). Our ambition is to produce electric batteries at the highest technological level while developing cleaner and more accessible mobility for all.

🔋 We are proud to manufacture, in our Billy-Berclau Gigafactory, the batteries that already power several electric vehicles available on the market (PEUGEOT E-3008 and E-5008, Opel Grandland, DS N°8, Citroën C5 AirCross, and Jeep Compass).

Since 2023, Block 1 of our Billy-Berclau / Douvrin Gigafactory has entered production. This first block marks a decisive milestone in the site’s history: after the launch of the first production lines, we are now engaged in a ramp-up phase—an essential step toward reaching full industrial capacity.

This period is marked by major technical and human challenges: ensuring process reliability, optimizing performance, strengthening skills, and embedding a culture of operational excellence.
To support this industrial acceleration, we are recruiting dynamic and passionate teams across Production, Maintenance, Quality, Engineering, HSES, and Logistics.

⚡️ Joining Block 1 means taking part in the very heart of ACC’s industrial development and contributing every day to the success of our Gigafactory.
