Process Development Engineer M/F

Main missions :

• Define and develop cell assembly processes from concept to pilot-scale validation (DoE, PoC, and scaling laws).
• Design experiments to understand process windows, critical parameters, and failure mechanisms in cell manufacturing.
• Lead pilot-line process definition, capability assessment, and technical readiness for scale-up.
• Interface with equipment suppliers to translate process requirements into custom or semi-custom equipment specifications.
• Collaborate with cell design and materials teams to optimize cell architecture for assembly robustness and yield.
• Establish process targets, control strategies, and documentation for handover to industrialization or manufacturing teams.
• Perform root cause analysis on assembly defects observed during development phases.
• Benchmark assembly technologies and processes against top-tier lithium-ion battery manufacturers.

Requirements :

• Bachelor’s degree or Master's degree in Mechanical, Electrical, Materials, or Industrial Engineering.
• At least 3 years of experience in lithium-ion battery process development, or 6 years for a senior role.
• Strong experience in lithium-ion cell assembly or formation processes.
• Proven experience in process development stages: concept definition, lab validation, pilot scaling, and technical transfer.
• Strong knowledge of DoE, statistical analysis, and data-driven process optimization.
• Experience with custom automation equipment development and technical specifications.
• Hands-on experience in dry room or cleanroom environments.
• Strong analytical skills using tools such as Python, Matlab, or Minitab.
