About The Company
Founded on a profound and long-standing know how in fuel cell technology, cellcentric, a 50:50 joint venture between Daimler Truck AG and the Volvo Group, is responsible for all activities along the entire value chain for fuel cell systems: from research and development through production to marketing of fuel cells to areas of application even outside vehicles. The ambition is to make cellcentric a leading global manufacturer of fuel cells, and thus help the world take a major step towards climate-neutral and sustainable transportation by 2050.
About the Role

Everyone's talking about sustainable energy - we're getting it on track.

We are a company with probably the most experienced employees in our technology field in the world. As a joint venture of Daimler Truck AG and the Volvo Group AB, we are responsible for all activities along the entire value chain for fuel cell systems: from research and development to production and marketing for use in trucks and other applications outside vehicles. The goal is to establish cellcentric as a leading global manufacturer of fuel cells, contributing to climate-neutral and sustainable transportation.

 

The team R&D and PD MEFA is responsible for the end‑to‑end process of the Membrane Electrode Assembly (MEA/MEFA): material specifications, component geometry, manufacturing process development, and validation of experimental principle components. That is why we are looking for you! If you are excited about materials characterization, measurement technology and data‑driven work, we look forward to your application! 

 

The main location is: Esslingen - Pliensauvorstadt

 

Responsibilities:

  • Support the adaptation and further development of characterization and testing methods, including measurement routines on coordinate measuring machines  and the design of leakage test fixtures.
  • Perform measurements and characterization activities on experimental MEFA prototype components, including:
    • Mechanical testing (e.g., tensile testing)
    • Metallographic sample preparation and microscopy
    • Imaging and characterization techniques
    • Leakage testing
    • Thickness measurements
    • Sample preparation for SEM analysis
    • Chemical analysis (e.g., FTIR, Photo-DSC)
  • Prepare, structure, and analyze measurement and test data, and contribute to the creation of technical presentations, reports, and documentation.
  • Collaborate closely with process development and simulation teams to integrate experimental findings into material and process models, supporting data-driven development and optimization activities

 

Required Skills and Experience:

  • You are currently enrolled in a degree program in Engineering or Natural Sciences, such as Materials Science, Mechanical Engineering, Physics, Chemistry, or a related field.
  • You are proficient in the use of Microsoft Office applications.
  • You have ideally gained initial experience in material testing, microscopy, or laboratory analysis.
  • You demonstrate a structured, independent, and analytical approach to work.
  • You possess good written and spoken communication skills in both German and English.

 

Benefits:

  • We offer you interesting, autonomous and varied activities with corresponding development prospects in a traditional company with a start-up mentality in one of the top future industries. 
  • With us you can arrange your working hours flexibly and also work on a mobile basis.
