What to Expect
Location: Gigafactory Berlin-Brandenburg
Duration: 12 months
Time type: Full-time
Start date: October 2025
As a Cell Mechanical Design Engineering Working Student, you will develop paradigm-shifting battery cells— the heart of every Tesla product— and the biggest lever on affordable, abundant, and performant EVs for all.
Our team habitually defies convention and designs each component and the full cell to the limits of physics. You’ll align inputs from multiple disciplines (supply chain, electrochemistry design, manufacturing & quality engineering) to develop new cell products, set & validate to requirements, and launch into mass production. Your environment will include battle-proven industry experts, high-aptitude recent graduates, and open access to a wealth of domain leaders across every Tesla department.
We feel immense daily satisfaction surrounding ourselves with high-ownership, empathetic, truth-seeking, continuously learning, mission-oriented people— join us!

• Own prototyping, basic testing and analysis (support advanced testing and analysis)
• Update existing specs and models with empirical data
• Perform laboratory tests and draw conclusions out of the results
• Design tools and jigs to improve component manufacturing and testing
• Conduct root-cause analysis of possible failure mechanisms and respond appropriately to resolve issues
• Understand the intricate multidisciplinary relations (trade-offs and synergies) in cell design engineering.
• Advance 3D/2D CAD modelling skills
• Learn how to organize technical work and effectively present it to multiple stakeholders

What You’ll Bring
