Cell Mechanical Design Engineering Internship (m/w/d) - Gigafactory Berlin-Brandenburg

Location: Gigafactory Berlin-Brandenburg 

Duration: 6 months  

Time type: Full-time 

Start date: March / April 2025  

The internship assignment: 

As a Cell Mechanical Design Engineering Intern, 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!
