Mechanical Process Simulation Engineer

Automotive Cells Company (ACC) est une co-entreprise créée à l'été 2020 par Saft-Total, le Groupe PSA et Opel (devenus Stellantis depuis)et Mercedes-Benz. Notre ambition est de produire des batteries au meilleur niveau technologique tout en rendant la mobilité électrique accessible au plus grand nombre.

Pour donner vie à cette ambition, à la fois pour notre centre de R&D et notre ligne test en Nouvelle Aquitaine, mais aussi pour nos gigafactories dans les Hauts de France et en Allemagne nous recherchons des personnes compétentes et agiles, notamment dans les domaines aussi diverses et variés que la R&D, l'industrialisation, la conception mécanique, les tests/prototypages… et toute autre fonction d'une entreprise en pleine construction.

Si vous cherchez à faire évoluer votre carrière au-delà de ce que vous aviez imaginé, si vous êtes passionné par la création de transports plus propres, si rejoindre l'industrie du futur vous excite, n'hésitez plus et rejoignez nous.

The Mechanics Process Simulation Engineer will model the unitary process involved in Li-Ion production using model-based numerical simulations. He/she will develop numerical models based on the current knowledge on the physics involved, using commercial or in-house simulation tools. The main topics considered will relate to multiscale composite materials - such as electrodes immersed in electrolyte solutions-, thin metallic materials, and the nonlinear response of cells to static mechanical loads.

He/She will use CAD/CAE tools (for example, Hyperworks) and Finite Element implicit or explicit solvers (for example, Optistruct or RADIOSS). He/She will adopt a multi-scale approach to analyze ongoing manufacturing issues with adapted tools (e.g. Digimat).

He/She will have cross activities with the Mechanical Modeling Team, and be in direct interface with industrialization teams.

He/She will support design and scaling-up of new processes; will answer to Industrial teams’ needs; will contribute to the design of the experimental procedures required to calibrate his/her models.  

He/she will be required to present the main results of his/her studies internally and to customers. He/She will remain up to date with state of the art process simulation activities through academic collaborations and manage external contracts and partnerships. He/she will manage his simulation environment.

As a Mechanical Process Simulation Engineer you should be familiar with the following tasks:

• Perform mechanical fully non-linear static/quasi-static simulation at pack, module and cell level
• Perform multi-scale analyses of nonlinear composite materials by using state-of-the-art numerical techniques (e.g., homogenization)
• Able to coordinate characterization test of materials exhibiting a highly non-linear behavior (porous media, foams) and metals in the elastic-plastic domain. Data Interpretation and data analysis
• Correlate models vs reality to improve company experience
• Support pilot line and gigafactories process setup and optimization by modeling processes
• Manage internal and external projects, contracts, while collaborating with internal teams (R&D, Industrialization, Projects, Simulation, …)
• Develop 0D/1D/2D/3D models, based on a pre-identified set of physics-based equations, using pre-existing commercial software or pre-existing in-house numerical tools
• Manage collaborations with suppliers, customers and strategic partners
• Contribute to the company roadmap
• Be up to date to the state of the art on its topic of expertise
• Support Intellectual Property monitoring and propose innovative patentable concepts
