MES Architecture Lead (F/M)

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.

🔋 Join ACC and be part of shaping the future of electric mobility. Our batteries already power the PEUGEOT E-3008 and E-5008, Opel Grandland, DS N°8, Citroën C5 Aircross and Jeep Compass — and soon, Mercedes!

About the role

As part ACC’s strategy to internalize critical Manufacturing Execution System (MES) competencies and Manufacturing Operations Management (MoM) capabilities, we are seeking an experienced AVEVA MES / MOM Architect to define, govern, and evolve the architecture of our manufacturing digital platform supporting battery Gigafactory operations. 

This role will be responsible for establishing and maintaining the target-state architecture of ACC’s AVEVA-based MES ecosystem, ensuring alignment between manufacturing operations, business objectives, industrial standards, and long-term digital transformation initiatives. The architect will provide technical leadership across the full application lifecycle, from solution design and integration strategy through development governance, deployment, supportability, and continuous platform evolution.   

Acting as the technical authority for MES and manufacturing operations solutions, the successful candidate will define architectural standards, development frameworks, reusable design patterns, and integration principles while ensuring scalability, reliability, maintainability, cybersecurity, and operational excellence across all manufacturing environments. 

The role combines solution architecture, software engineering leadership, industrial digitalization expertise, and stakeholder engagement, working closely with Manufacturing, Engineering, Quality, IT, Data, Cybersecurity, and external technology partners to build a sustainable, future-proof, and internally owned manufacturing platform. 

In addition, the architect will play a key role in building knowledge from external partners to ACC teams, developing internal competencies, reducing dependency on external integrators, and helping establish a long-term Manufacturing Digital Center of Excellence.
