Join Max Joule, an innovative deep-tech startup developing next-generation battery cells and energy storage systems for industries including defence, space, medical, and mining.

As a Mechanical Engineer, you will play a key role in designing battery cells, battery packs, production tools, and manufacturing equipment. Working closely with the founders, you will contribute to product development from concept through testing and manufacturing while helping build the future of European battery technology.

Your responsibilities will include:

• Designing battery cells, battery packs, fixtures, tools, and manufacturing equipment using CAD
• Creating and maintaining technical drawings, design files, parts libraries, and engineering documentation
• Performing CFD thermal simulations and supporting thermal design optimization
• Designing and improving manufacturing tools and production fixtures
• Planning, executing, and evaluating Design of Experiments (DoE)
• Supporting prototype development, testing, and product validation
• Identifying design challenges and implementing practical engineering solutions
• Maintaining accurate documentation for designs, tests, engineering changes, and results
• Contributing to the continuous improvement of manufacturing processes and production equipment

During your first months, your main focus will be thermal modelling of battery cells and battery packs, battery cell CAD design, and the development of manufacturing fixtures.
