  • Create high-reliability embedded solutions suitable for long-term field deployment.
  • Support pilot installations and refine firmware based on customer environment findings.
  • Develop automated testing strategies for firmware validation.
  • And continuously improve firmware to enhance performance, security, and user experience.

About Us
Working with us at Sensorberg means having an excellent work-life balance with family-friendly working hours in the heart of Berlin. Our main company language is English and our team is very international. We have a culture of openness, collaboration and creativity where everyone is encouraged to take responsibility for projects and share their views with the team. It is natural for us to give everyone the support, encouragement and freedom they need to reach their personal potential. This includes the possibility of further development and training as well as a hybrid work model.

We live transparency through an open and honest exchange of information and offer a positive working atmosphere, because we believe that only in this way a good and relaxed cooperation in the teams can function and be promoted. Our field of work is dynamic and rather quick. We counter this with flat hierarchies and short coordination paths. To support the daily work routine and teamwork we always have fresh coffee, tea and other drinks, as well as fresh fruit. In addition, we live a modern office and work design, in which there is room for productivity as well as exchange with colleagues and cuddles with dogs – if you have one feel free to bring it to work with you
