Job Description

This Cell Test Engineer will validate lithium-ion cell and battery safety performance through testing at Tesla's Gigafactory Berlin-Brandenburg. Responsibilities include developing and executing tests, writing test plans, analyzing results, and preparing presentations for executives. The role requires hands-on experience with test equipment (cyclers, environmental chambers, DAQs), data processing software (MATLAB/Python), and potentially 3D design/CAD. The engineer will work within a cross-functional team, collaborating with internal and external stakeholders. Experience with hazardous materials and a strong understanding of cell/battery technology are crucial. Flexibility to perform both cell and battery-level testing is essential.

Must have:

Experience with cell/battery testing equipment
Test plan creation & execution
Data analysis & reporting
MATLAB/Python proficiency
Hazardous material handling experience

Good to have:

3D design/CAD skills
SQL experience
High Voltage Training Class 3
Experience in aviation or power electronics

What to Expect

Tesla is accelerating the world's transition to sustainable energy. Revolutionary strategies and products were developed within a few years and successfully launched on a large scale. This is only possible through extraordinary speed, innovation and efficiency.

Gigafactory Berlin-Brandenburg forms the perfect basis for rolling out Tesla's incredible success story in Europe. The most important pillar for this are our employees. Their passion, motivation and engagement ensure that we achieve our goals. We are looking for you to continue and expand this success story together.

This test engineer will work in a team to validate lithium ion cell and battery safety performance through testing. They will develop and execute tests to evaluate performance and validate requirements.

What You’ll Do

Be a member of a cross functional product development team and own validation of cell and/or battery product requirements. 
Note: Flexibility to perform cell and battery level testing is required. Assignments and projects will be decided based on previous experience and current project needs. First projects will be focusing on batteries.
Execution and maintenance of cell and/or battery tests using cyclers, specialized temperature control fixtures, environmental test chambers and data loggers.
