Responsibilities
The Mercedes-Benz Group AG is one of the most successful automotive companies in the world. With Mercedes-Benz AG and the business units Mercedes-Benz Cars, Mercedes-Benz Vans, and Mercedes-Benz Mobility AG, the vehicle manufacturer is one of the largest and most successful providers of premium passenger cars.
In Group Research & Mercedes-Benz Cars Development (RD), we are shaping the car generations of the future. By this, we mean innovative products with the highest quality and safety standards, as well as efficient development processes.

In this role, we are leading the execution and design of test bench trials, testing cells, modules, and entire batteries with control units thoroughly. In addition to hardware, software validation is also a significant testing task in the safety environment. Thus, we ensure transparency about the maturity level of the test objects on our internal and external test benches.
Parallel to series certifications, we also support various pre-development projects. Our goal is to test as realistically as possible, to carry out safety validation and functional testing efficiently, to process results in a targeted manner, and to expand and utilize our testing expertise to help shape the future of electromobility together with the specialist departments.

- Hardware-related development and adaptation of battery measuring technology, including fault analysis
