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/prototypageset 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.

**Job description**:
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
