Viessmann is a leader of technological progress in the heating industry, with its Wrocław based R&D Center developing the company’s products in the field of software and electronics. We use only state-of-the-art technology and equipment to translate the results of our work into innovative solutions to be applied in the near and more distant future. 

In model-based development of ECU application software, testing the software is an important factor in meeting our high quality standards. We are therefore looking for support to strengthen the team in the model-based validation and verification of the software.
