Systematically selecting and designing laser welding technologies in the battery environment
Developing a methodology for designing weld seams based on requirements and enabling the transferability of results to other geometries and material alloys
Optimizing seam geometry through modeling and optionally integrating AI methods
Establishing correlations, such as between bonding area and strength requirements of laser weld seams in battery stacks
Considering FEM analysis of material behavior

Requirements:

Good to very good university degree qualifying for doctoral studies in mechanical engineering, automotive engineering, physics, or a comparable qualification
Knowledge and experience in the field of laser welding technology (specifically: aluminum alloys), optionally laser welding expert or welding engineer
Materials expertise in the field of metallurgy, ideally welding or solidification processes
Knowledge of finite element modeling and phase field modeling
Knowledge of statistical experimental validation methods and test execution
Outstanding initiative, ability to work in a team, and structured approach to work
Outstanding communication and presentation skills
English language level B2 and German language level C1

What we offer:

Attractive salary & 30 vacation days (+ 24.12. and 31.12. off)
